Sites don't recover after canceling a browser

Everything was ok, but exidently (maybe after some update) my firefox browser just stopped recovering my pages after closing and reopening it. YES, it is turned on in settings and I tried every single advice I found, this fucking browser just don' do it. I don't have extensions. There are backups files in sessionstore-backups, but it doesn't load it. I looked at sessionstore-logs there was a one error(date is about time recovery stopped working), which was caused by lack of free space on my disk, but now I have a lot of free space and it still doesn't work
