Lost Windows and Bookmarks after upgrade of Firefox

I tried updating Firefox and it failed me. At the end of the day of work I did an automatic update. I shutdown my computer and the next day Firefox worked intermittently as in it would load pages and some it wouldn't load. I thought it was my internet connection and verified in another browser. The internet connection was okay, it was a Firefox issue. Then I notice the Firefox icon was a generic icon. I'm now lost all my bookmarks, which I thought I had in Firefox sync and open windows / tabs. This is a bit frustration that Firefox failed like this and caused me to lose data.

Hey!!

Check Troubleshoot Mode in Firefox which may help you troubleshoot tour firefox. When in troubleshoot mode, open some websites to check if there are still any problems. If if everything is OK, you should close Firefox and do the "Refresh Firefox" option on the article. If the issues persist, I recommend you to uninstall Firefox. Note that uninstalling firefox does not remove your data/settings. When you uninstall again, log-in with your Firefox/Mozilla acount, and all your bookmarks should be back (open Manage Bookmarks if you can't see them right away.
