Now running TBird 68.3.0 (32bit) on a Windows 7 Pro pc; it will go offline after Jan 14 so I just purchased a Win 10 Home pc and wonder if it is possible to do a copy/backup/transfer of Tbird via a thumb drive to the new Win 10 pc and preserve all of my add-ons, profiles, settings and contacts to the new pc without starting from scratch.

Unsure at this point if TBird for Win 7 and for Win 10 are interchangeable. If not I would presume that I would have to download and install the Win 10 version on the new pc and then find a way to incorporate my contacts and reinstall add-extensions (realize some may not work on Win 10).

It has been years since I installed TBird on the Win 7 pc so at age 88 I will be struggling up the relearning curve with the program install on Win 10.

Any tips, insights or step by step guidance for accomplishing the above would be very much appreciated.

It's really simple Frank. You don't need backup programs or anything like that. Just go to the following folder:


Of course you need to put your name where mine is (Larry). Copy the folder "Thunderbird" and paste it into the same folder on Windows 10. Then just install TBird 68 and you are good to go. I assume you know how to copy that profile to your USB stick from Windows 7.

I never really used Windows 7, but I have played with it a little and as I recall the profile is in the same roaming folder as it is in Windows 10. Heck, I brought my profile from Windows XP when it used to be in Documents & Settings. I went straight from XP just last year to Windows 10. Shows you what a laggard I was.
