Automatically Reduce Images Before Sending In Thunderbird
Photos these days can are often in the Megabyte range which makes it difficulty to transfer them via email or other means. Email is special as it has a it is usually limited in the amount of Megabytes you can send per email. The limit is usually in the 15 to 25 Megabyte range, with companies like Microsoft working their way around the limit by hosting the attachments in the cloud and replacing the attachments with links to the cloud hosted files instead.
Some users help themselves by running their photos through image optimizers like Riot, VSO Image Resizer, or a dozen of additional image resizers optimized for that task.
The Thunderbird extension Shrunked Image Resizer handles the task automatically whenever you send images as attachments. The extension displays a configuration dialog whenever you do that allows you to select a desired maximum resolution for each photo, as well as the quality of the converted images. You can furthermore define a minimum file size in the extension options. All images below that size are not converted at all, while all greater than the selected size are.
Once you have made your selection you will see a progress bar coming up that indicates the conversion progress. The process itself should not take long, and you will notice that large images are reduced significantly in size by it.
There is no preview of the output image which is one of the things that could be improved by the author, as here is no way currently to check the quality of the converted images before they are send out. You could send the first batch of images to your own address to verify the quality of the conversion before sending them to other recipients.
Shrunked Image Resizer regardless of that is a useful extension for Thunderbird users who often encounter issues when sending photos as attachments in the email client.

Mail Hops Adds Routing Information To Thunderbird
One of the things that you can do to validate an email is to verify that the sender is genuine. A basic example would be to look-up the location the email originated from. Think of the following: You are expecting an email from your friend living in the same city that you are living in. When the email is now indicating that it has been send from a different country, you might use the information to be more cautious about the email than you’d otherwise be.
Mail Hops for the Thunderbird email client adds routing information to each email which indicate the origin of the email, and the locations it passed through before it reached your inbox.
Installation of the extension should not take long.
You can download Mail Hops at the official Mozilla Thunderbird add-ons repository.Open the Thunderbird software, and select Tools > Add-ons from the menu.Locate the settings button next to search and select Install Add-on from File from its context menu.Select the Mail Hops extension file that you saved on your computer, and follow the installation instructions.Restart Thunderbird to complete the processWhen you now open an email in the program, you will see the new Route row that has been added by the extension to the header (it is displayed both in compact and detailed headers).
The extension looks up the information on the Internet, and displays the country and city of origin, and the distance between the sender’s location and your own. It furthermore can display all hops with a click on the hops link in the header, and mapping information. The latter are opened in a new window and use Google Maps by default.
Here you see all locations laid out on the map with additional information listed in a sidebar on the left. Mail Hops offers two options: You can switch from Google Maps to Bing Maps if you prefer Microsoft’s mapping service, and from miles to kilometers.

Thunderbird Indicators Tell You If A Message Is For You, A Group, Or A Mailing List
You probably know about Gmail’s Indicator setting which adds group and single message indicators to all mail folders. You can enable the feature with a click on the Settings button, the selection of Settings from the context menu and scrolling down on the page until you see the Personal level indicators preference.
The very same feature has now been ported to the Thunderbird desktop email client. The Personal Level Indicators extension for Thunderbird needs to be downloaded from the Mozilla website, before it can be installed manually in the program.
For that, you need to click on Tools > Add-ons to open the add-ons manager, and then on the small button next to the search field in the upper right corner. Select install add-on from file and select the add-on from your hard drive.
This add-on brings Google Mail’s “personal level indicators” feature to Thunderbird. It displays little arrows next the email’s subjects so you can tell if a message was addressed to you, a group, or a mailing list. A single arrow (›) indicates that a message is sent to you, and a group of others. A double arrow (») appears when the message is sent only to you. Arrows won’t appear next to messages sent to a mailing list.
The add-on is installed, but you need to enable it in the interface before it becomes available. Right-click a column in the inbox and select the Personal Level Indicator option there. This enables the feature for the selected inbox. Keep in mind that you need to activate it separately for every folder that you want the extra information to appear.
Why would you want to display the indicator in first place? It may give you a quick overview about each email’s recipients so that you can ignore emails send via mailing lists for instance and concentrate on personal emails instead. It can also be handy to see whether you’d need to use reply or reply all for a particular message.

Add Multiple Clocks To Thunderbird
I recently switched from using the Fox Clocks extension in Thunderbird to the lightweight Simple Clocks alternative (with a size of 100 Kilobyte compared to Fox Clock’s 700 Kilobyte). Both programs can be configured to display the time of select locations in the world. That’s extremely useful if you are communicating with people from all over the world. The information can aid you in a variety of things, from calling contacts at appropriate times to postponing a reply to the next day as it won’t be read by the client until the next day.
Simple Clocks can display clocks both in the Thunderbird status bar or in a toolbar instead. When you first run Thunderbird after installation of the extension, you need to start adding locations as the locations list is empty on first start.
This is done with a right-click on the status bar icon and the selection of Locations from the context menu. Here you can then use the countries and timezones menu at the top to select a location with the mouse (a double-click adds the location to the status bar), or enter your own country, city and timezone information in the program.
All locations and their current time are displayed in the status bar afterwards. The selection of options from the context menu opens a configuration window. You can change the time format from 12-hour to 24-hour here, select whether you want to add date information or move the clocks to another location in the status bar or to a toolbar.
Simple Clocks can display flags next to each location and time. If you select that option, you first need to download flag information in the Flags tab.
Another interesting option is the ability to change style options. You can change global styles in the settings window, or styles for individual locations in the Locations window instead.
Alarms can be configured for each location individually, and a message can be attached which can act as a reminder for important tasks.
Thunderbird users can download the excellent extension from the official Mozilla Add-ons repository.

Thunderbird 10.0.1 Update Released
Mozilla has just released an update to the Thunderbird email client, shortly after releasing a similar update for the Firefox web browser that brought the version to 10.0.1. Thunderbird 10.0.1 is a stability and security release, and as thus a recommended update for all users of the messaging software.
The update is already available, and Thunderbird users can either download it from the official developer website or use their client’s internal updater to download and apply it. A click on Help > About Thunderbird performs the update check and displays the current version of the program in a small window.
Lets take a look at the changes in Thunderbird 10.0.1.
The security advisory page over at Mozilla offers details on the issue that has been fixed in the update. It affected not only the email client, but also Thunderbird and SeaMonkey as well.
Mozilla developers Andrew McCreight and Olli Pettay found that ReadPrototypeBindings will leave a XBL binding in a hash table even when the function fails. If this occurs, when the cycle collector reads this hash table and attempts to do a virtual method on this binding a crash will occur. This crash may be potentially exploitable.
The change log lists several fixes to improve stability without going into further detail on the subject. Sören Hentzschel mentioned a crash in the client’s importer when importing mails from Microsoft Outlook.
The release of Thunderbird 10.0.1 comes less than two weeks after the last update that moved the version of the email client to 10. Thunderbird 10 introduced a new right-click search option to search directly from within Thunderbird. Results are either displayed directly in Thunderbird in new tabs, or in the default web browser whichever is preferred.
Other changes include new keyboard shortcuts and an extension compatibility change that should reduce the issues that Thunderbird users have in this regard.

Email Client Thunderbird 10 Released
Regular readers know that Mozilla has synchronized the release schedules for both the Firefox web browser and the Thunderbird email client. Both applications share the same rapid release process, and both are usually updated at the same day.
Mozilla today, after releasing Firefox 10, has also released Thunderbird 10, a new version of the email software.
Thunderbird too is now flagging add-ons as compatible by default. Add-ons ship with minimum and maximum version compatibility information. The issue previously was that add-ons were flagged as incompatible if the author failed to update the version information in time. This made it difficulty for developers to keep their add-ons compatible with the latest releases.
Another change is the native integration of the Open Search extension in the email client. A right-click now displays an option to search for the selected term on the Internet. This is handled in the email client and not in the default system web browser.
The rendering component uses the Gecko 10 engine that the Firefox web browser uses as well.
Users who do not want their searches to open in the email client can set the preference mail.websearch.open_externally to true. This is done with a click on Tools > Options, switching to Advanced > General, clicking on Config Editor in the menu and filtering for the above preference. Just double-click it to toggle its value from false to true. Is there a way to disable web search completely? Not that I’m aware off. Maybe there is a preference but I have not found it yet.
Two new keyboard shortcuts have been added to Thunderbird 10, in addition to the changes outlined above. It is now possible to add attachments to messages with the Ctrl-Shirt-A (Command-Shift-A) shortcut. Named anchors can now be removed with Ctrl-Shift-R (Coammdn-Shift-R), and messages in the message reader and compose window can now be zoomed with the scroll wheel (Ctrl-Scroll Wheel).
Thunderbird users should have received update information by now in the email client. New users can download the latest version for all supported operating systems and languages from the Mozilla website.

Quickly Enable or Disable HTML Messages In Thunderbird
One of my security and privacy recommendations for desktop email users is to disable HTML emails. This basically turns every email that you receive into a plain text email that does not load anything from third party servers. Once in a while though you may stumble upon an email that you need or want to view in HTML. If you have disabled HTML you’d have to enable it again by going to View > Message Body As > Original HTML or Simple HTML to do that. And once you have finished reading the message, you need to perform the very same steps to disable HTML for all emails again.
Sebastian recommended the HTML Temp add-on for the Thunderbird email client to switch HTML messages in Thunderbird on or off more effortlessly.
Download HTML Temp from the official Thunderbird add-ons repository. Once it has been downloaded open up the email client and click on Tools > Add-ons to open the add-ons manager. Click on the options icon on the left of the search all add-ons form there and select Install Add-on from file from the context menu.
Select the downloaded add-on on your local computer and install it in the email program. You need to restart Thunderbird before it becomes available.
The add-on adds the current message display preference in the lower right corner of the status bar. You can now right-click on it to switch to Simple HTML or Original HTML whenever you need to view a message in HTML. Once you are done you use the same method to switch back to plain text messages.
The add-on allows you to move a button with the same functionality to one of the toolbars. This can be helpful if you have disabled the status bar in the program or prefer to click on the button in the header area of the email client.
Update: Sebastian mentioned that the toolbar button behaves different from the status bar button. When you click the toolbar button HTML will be enabled only for the active email and no other. This means that you do not have to click again to restore the plain text message view.

How To Make Thunderbird More Secure
I have been a user of the desktop email client Mozilla Thunderbird for the past five or so years. In that time, I have modified the default settings and behavior of the client to make it more secure against attacks and other malicious activities and issues. This guide acts as an overview of what I have done in those years. Please note that while it makes your email client securer, it does not make the program invincible. Common sense is still one of the most powerful weapons in a computer user’s arsenal.
I also have to say at this point that I’m not including add-ons in this guide. This guide only looks at the native options that Thunderbird offers. The majority of changes should also be applicable in other email programs.
1. Disable HTML messages
I get it. HTML messages look nicer. You can do all kinds of things with HTML messages that you cannot do with plain text messages. Plain text messages on the other hand only display textual contents and nothing else, which reduces the likelihood of exploits.
You find the setting under View > Message Body As > Plain Text.
2. Disable JavaScript
The developers have removed JavaScript in Thunderbird 3 for emails completely. There is no option to enable JavaScript for emails. JavaScript for RSS feeds is enabled on the other hand. Thunderbird users who do not use RSS or do not want JavaScript in their feeds can disable it the following way. Click on Tools > Options > Advanced tab > Config Editor to open the advanced configuration window.
Filter for the term JavaScript and double-click JavaScript.enabled to set it to false if it is set to true.
3. Use SSL
You should furthermore make sure that all of your email accounts use SSL connections to protect against snooping and eavesdropping. Click on Tools > Account settings, and there on the Server Settings listing underneath each email account.
Check the help pages or contact support if None is selected under Connection Security. You also need to click on Outgoing Server (SMTP) at the bottom of the listing to see if all outgoing servers are also using SSL for connections.
4. E-Mail Scams
Go to Tools > Options > Security > E-Mail Scams and make sure that Tell me if the message I’m reading is a suspected email scam is enabled. This basically checks back if the email is a known scam email and warns you if it is.
5. Master Password
If you are working on a multi-user PC or want to protect your email passwords from unauthorized access, you should consider setting a master password in the email client for that purpose. Anyone with access to the PC can look at all email usernames and passwords if they are not protected with a master password.
Click on Tools > Options > Security, and check the Use a master password box there to enable the option. You are then asked to enter a password which from that moment on will protect the password database from unauthorized access.
Thunderbird displays a form on start up that asks for that master password. The password quality meter visualizes the strength of the selected password.
6. Disable the preview pane
Thunderbird uses a layout with three panes by default. Email accounts and folders on the left, the email messages on the upper right, and the preview pane at the bottom right.
Email previews are automatically displayed when you select a message in the email client. You may want to disable that feature as it may be used for malicious purposes. Please note that this is unlikely, especially if you have disabled HTML messages and JavaScript.
The easiest way to disable the message preview pane is to press the F8 key on the keyboard. You can re-enable the pane easily with another tap on the same key.
7. Display All Headers
Email headers help you find out if an email is legit or fake. Thunderbird displays a compact version by default which cannot be used to verify an email address. You can enable full email headers with a click on View > Headers > All.
Please note that Thunderbird limits the space available for email headers on its page. You can scroll the page by holding down the left mouse button and moving the scroll wheel up or down.
Closing Words
Add-ons can furthermore improve security but that’s outside of the scope of this guide. Let me know if you are interested in a list of security related add-ons for the Thunderbird email client.
Have additional tips you’d like to share? Let me know in the comments.
