Turned on computer this morning and opened firefox the first thing as I usually do. There was an update today and it failed to install so firefox asked me to send a crash report and restart which also failed -this happened 4 times before it asked me to refresh. I did not know that refresh implied it would wipe everything (the only choices were to start and to refresh and starting would go nowhere as what was previously shown). Firefox also failed refreshing, it froze for about 10 min as it was close to finishing. So after killing the process and starting again I noticed that it did not save my previously opnened tabs and that they were not in the history. So as I usually du during this occurrence, I restored the system to a save point (2017/08/05 2:00AM, Windows). My previously opened tabs were back but then I noticed I had no extensions or addons, so I signed in to sync hoping that would restore the addons/extensions but it did not. And now I just discovered that I don't have the saved login information anymore either.

Any Suggestions as to how I can retrieve my browsers previous working state?
