Suddenly Mozilla Thunderbird started crashing on me. I found out that it was the webmail addon “Hotmail 1.2.15 (live)” which creates the problem. The solution is to upgrade to the newer version 1.2.17, but unfortunately this has to be done manually:
- 1) download the new version of the addon http://webmail.mozdev.org/installation.html (right-click save as).
- 2) start mozilla thunderbird in safemode.
- 3) drag & drop the downloaded extension into the addon manager.
- 4) restart Thunderbird.
