So I used Firefox on my PC and on my android separately. Now i need to backup my android device since I'll be restoring it to factory defaults. I made an account and synced my tabs, bookmarks, logins and history to my email. But I couldn't transfer my tabs from my smartphone to my PC because I thought once they came to PC, I could simply back them up.

If there is a better way to backup tabs, bookmarks and stuff from an android device to PC then please shed some light on it because I can't get it to work...
