is it possible to undo the reset firefox feature in troubleshooting information?


I recently started getting an ad for firefox on android every time I start firefox and searched for a way to stop it. The reset firefox button seamed like a good idea but I would prefer to restore firefox back to how I had it. Is there a way to undo the reset feature?

Yes, copying files from the "Old Firefox Data" folder on the Desktop should work.
