Lost all Settings and Style Sheet: Where are they stored?

[viking2]

Somehow, I lost all settings and the Style Sheet. I have a backup of my Firefox Profile. Can I copy the settings and Style Sheet to my working Firefox profile?

I tried to copy [email protected] in the extensions folder, but that didn't work - where are the settings and Style sheet stored?

To answer my own post (in case someone else looks for an answer):

1. I put this in the address bar: about:debugging#/runtime/this-firefox
2. For Tree Style Tab, I found:
   Internal UUID c7884c28-d433-4322-b043-4dc15065097f
3. I searched for "c7884c28" in this directory: ~profile/storage/default/moz-extension+++...
4. I found two folders:
   moz-extension+++c7884c28-d433-4322-b043-4dc15065097f
   and
   moz-extension+++c7884c28-d433-4322-b043-4dc15065097f^userContextId=4294967295
5. I moved away these folders in my current profile
6. I then copied the ones from my backup to the current folder

All my settings and Style Sheet were restored :-)
