I have signed into my Firefox account on my parents computer in order to see my bookmarks & have saved passwords, etc easily found, signed into & used. Sync is off but after I sign out bookmarks & password still on this computer. I don't want to remove these bookmarks & passwords from my Firefox account on my home desktop or my phone - just from this one computer. Research I found say a Firefox account not for this "function" - but now that I've done it is there NO way to remove it & not have to start from scratch & thus lose all the saved data, extensions, etc.???
