Tips & Tricks

Managing Updates on Mozilla Thunderbird

Thunderbird performs the update by default. Whenever a new version is released, it will automatically update itself. You can check this on the Settings and change it to manual if you’d like to. 

Here’s how:

  1. Click the three dashes or menu bar to go to the Settings.
  2. Choose Preferences > General > Thunderbird Updates.
  3. Select ‘Check for updates, but let me choose whether to install them’.
  4. Save it.

We strongly recommend enabling the automatic Mozilla Thunderbird updates to get the latest security fixes and performance improvements. 

Mozilla Thunderbird Manual Update

If you turn off the automatic update on Mozilla Thunderbird, in return you have to install it manually. It’s quite easy to do though.

Here’s how;

  1. Hit the menu bar and choose Thunderbird menu > About Thunderbird.
  2. Thunderbird will check for updates available and download them automatically if any. 
  3. Once completed, click ‘Restart Thunderbird to Update’

Viewing Saved Password

Mozilla Thunderbird keeps your username and password safe in the password manager. In case you forget your password, you can see it on the password manager. 

  1. Click the menu bar and go to Thunderbird menu > Preferences.
  2. Go to the Security panel > Password tab > Saved Passwords.
  3. Choose Show Passwords to see the password.

Changing and Deleting Password

You also have the authority to change and delete passwords as well as the username that you have saved. 

Do these simple instructions:

Open the Password Manager as shown in the previous section.

  1. To change your username and password on Mozilla Thunderbird, press down the Ctrl button and click the one that you want to change. 
  2. Choose Edit Username or Edit Password to proceed.
  3. To delete the username or password on Thunderbird, choose Remove or Remove All if you wish to erase all accounts saved at once. 

Backing up All Folders, Emails, & Settings

Unfortunately, to backup your profile that consists of all folders, emails, and settings, you must do it manually. Up to now, Thunderbird hasn’t added any feature that lets you do it in a single click.

Instead, do the following instructions:

  1. Close Thunderbird if it’s still open.
  2. Click Finder. On the menu bar, choose Go, press and hold the option/alt button and click Library
  3. Open the Thunderbird folder > Profiles folder. If you only have one account or profile, the folder would have ‘default’ in the name.
  4. Hold the Ctrl button and click the profile folder (e.g. xxxxxxxx.default) at the same time. 
  5. Choose Copy.
  6. Press down the Ctrl button and choose the backup location. Then, choose Paste item.
