Latest release totally EFFED UP

[Pollyanna]

Yesterday, suddenly, I opened firefox and all my pinned tabs disappeared, history disappeared, the open tabs that were there are gone and it looks like a fresh installation.

This is true for all my devices. WTF, firefox? THis is not good. I will have to stop using firefox because I cannot work with a browser that does not remember my history, pinned tabs, nor open to the tabs that I closed. 

I checked all the settings and all the settings are correct. I have not found other people complaining about this problem yet, which is why I'm posting this.

Seriously, I'm going to stop using firefox if this doesn't get corrected today. I cannot afford to be f*cking around with this sh*t.

I didn't have the experience you describe, but mine hung and I had to use task manager to kill it. But it's still not completely dead because I can't start it even after shutting down my computer. It says there's no active processes running when I try to run taskkill command, but yet when I try to open it it tells me it's already running. How does that work?

@Pollyannajust checking it's definitely not just a different profile it has opened up right?

Type about:profiles in the address bar, hit Enter, and your other data (tabs/history/bookmarks) could be in a different profile?
