Is the Thunderbird version number stored in the AppData somewhere please??
Fortunately I have the hard drive from the Win 7 laptop as it was the motherboard that failed - but now find myself with Win 10. I have researched online to see how I can discover what version I was running on the Win 7 but can't find an answer. I can find the user\appdata\ - if I could simply find what was the older version, uninstall the present loaded version, find and load this older version then presumably I could simply transfer the old AppData into the correct area of Win 10? I don't want to lose all my emails. contacts etc etc and the 68.8.1 version files look very different from the version on Win 7 - I've been using it for a long time Is the version number stored in the AppData somewhere please?? Thanks Suzanne

Since the version of TB on W7 can't be newer than the version on W10, 68.8.1, you shouldn't have any problem copying the Thunderbird folder from ../AppData/Roaming on the W7 drive, deleting the current ../AppData/Roaming/Thunderbird folder in W10, then pasting the W7 Thunderbird folder into AppData/Roaming. There might have been problems if the W7 TB was newer than the W10 TB, but that's not the case here.

But to answer your question, there is an updates.xml file in C:\ProgramData\Mozilla\updates\8216C80C92C4E828, where the 8216C... string may be different on your computer, that can be viewed in a text editor. The TB version history is shown in this file.

Thanks very much - just to play safe I copied & pasted the mab files just to check all would be ok - which it was of course. Getting my head around WIn 10 is a bit of a challenge - especially as I was pushed! So thanks again - Suzanne
