Thunderbird has just crashed 15 times in a row. I keep getting the attached crash reporter, which just pops up again if I choose restart. I have tried to start it in safe mode, same thing happens. I have tried deleting the parent.lock file

I'm desperate not to lose my mail history or folders or filters.

Please help.

re :I'm desperate not to lose my mail history or folders or filters.

Make a backup copy of whatever is currently stored and paste into an external drive. Exit Thunderbird - make sure it's not running.

Access: C:Users/Username/Appdata/Roaming folder. Copy the 'Thunderbird' folder and paste in external drive.


How to access Appdata - see image below as guide.

When you have got a copy of the 'Thunderbird' folder in a secure location

First let's see if the Windows cache is messing things up. This time it is in the Appdata 'Local' folder.

Access: C:Users/Username/Appdata/Local/Thunderbird/Profiles/ delete the 'profile name' folders - do not worry. This is the 'Local' Windows cache and not your profile storing emails.

then start Thunderbird. If you get access go to this place first: Help > More TRoubleshooting Information scroll down to Crash Reports to see Report ID Look for lines that start with bp- select/highlight the bp- line and use right click - select 'Copy' then paste into this forum
