I use firefox to work. I'm web developer and in the firefox have instlalled 3 complements and 8 plugs.
When use Firefox, and in different tabs open: GMAIL, web normaly, other web, google, conection with my server plesk, ... Normaly use 6 to 8 tabs in differents sites, some moments firefox run very slow, at the moment, in one web, it stop, dont run and response.
Than, I close firefox, pause 10 seconds to firefox service stop and reopen, it open all the last webs and popups visited today. Sometimes, it even opens popups that had been closed for some time ago, sometimes it crashes.
In the same day, it success two or three times.

Completely Disabling Session Restore
Check and tell if its working.
It is possible that there is a problem with the files sessionstore.js and sessionstore.bak in the Firefox Profile Folder.
Delete the files sessionstore.js  and sessionstore.bak in the Firefox Profile Folder.

If you see files sessionstore-##.js with a number in the left part of the name like sessionstore-1.js then delete those as well.
Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost, so you will have to create them again (make a note or bookmark them).
