Fihaonambe Fanampiana Firefox ho an'i Android

I just opened firefox on my samsung galaxy note 8 and all of my tabs are gone. I have not seen the "restore previous sessions" option, nor are they in the "recently closed tabs" part of my history. Please help. Is there any way to restore the tabs?

Now that firefox Android supports addons, please someone make addons for History export..

Is there any other better way to export history.. I have tried sync.. but there seems to be some limitations in sync, it didn't sync all the history..

For some reason my browser occasionally jumps over to a private browsing tab and I may never realize Firefox has performed this action. I may continue with my research for any length of time when I may need to look at something other than my browser, say jump over to a Note or some other function not having to do with Firefox, when I return I find maybe an hour of research has automatically been closed and of course there is no record of that lost work. This function is really frustrating additionally it's tricky that a link to another site or page of information can cause the Firefox Browser to open the following tab in Private Mode, then automatically close when it becomes necessary to look at some other functions on my Android device, everything is wiped out gone lost no way to retrieve the info.

What ever happened to Lazarus, the app that always brought back lost work, private or otherwise? That was an excellent and very helpful tool. Is there some other way unknown to me where I can retrieve those closed private tabs, how do I stop the links from auto-opening privately, and I'd like to know how to stop private tabs from closing when I leave those tabs to focus on something other for a split second.

Please advise. Thank you.
