Thunderbird Upgrade Problems - version 1.5

You may have experienced problems upgrading from Thunderbird 1.07 to version 1.5. I did! In particular, upgrading caused failure of Enigmail, and there were issues using the United Kingdom / Great Britain spell checker.

One thing to bear in mind is that you will not have to delete your old Thunderbird profile, which will save much heartache if you can't recover your profile.

If you have problems after installing Thunderbird, follow these simple steps:
  • Start by uninstalling Thunderbird (for Windows users this would involve the Add/Remove programs applet from the Control Panel).
  • Delete the main Thunderbird folder, which should be located at C:\Program Files\Mozilla Thunderbird.
  • Reinstall Thunderbird.
Then reinstall your extensions. If this doesn't work, rinse and repeat.

The spell checker is particularly problematic. I found that the UK dictionary wasn't included even though I chose to download the British version of Thunderbird. Moreover, the spell checker marked every word as being misspelled. You can find the appropriate dictionary from Mozilla's dictionary page. Install the file as you would for any other extension. Note that the dictionary will not appear in your list of extensions. To activate the British (or other) dictionary, go to Tools → Options → Composition → Spelling. Make sure "Enable spell as you type" is checked, then choose the dictionary you want. You may have to restart Thunderbird a few times before the dictionary begins to work properly.
