I use Firefox as my default browser for my PC, Mac and Android phone. Suddenly, all of my bookmarks and home screen shortcuts have disappeared... I'm guessing after an update. I'm also guessing I'm not the first person with this issue I have tried syncing multiple times as well as uninstall and reinstall... Nothing, they are all gone. They are all still there on my PC versions. Can't find any tab for bookmark backups, Can you help me get these back?
