I have used the OneTab browser extension for years. Mac computer ran out of space but was completely backed up. Got new computer. copied Firefox profile from the and updated the profiles.ini to use the backup data.
I used a backup dated 12 Feb 2026.
I was able to restore my bookmarks and passwords from this profile, but they seem to be from many years ago. I was not syncing to my Firefox account and saving the passwords to my computer. i assumed they would be in a bakup. None of my OneTab items were restored.
I wonder if part of the problem is that Firefox wants to ( and did) update my new computer to Firefox 145 or 147. I don't know which Firefox was running when I had the issue but I suspect it was older.
All of the storage/moz-extension files are there and firefox is using the correct profile data. Is there any way to find/read/extract the OneTab history? Where should I look? I contacted OneTab and all they could tell me was to look in storage/default/moz-extension.. ( nothing readable there) Thanks
