My Firefox mobile tabs have stopped updating. Every time I close and reopen the app, it gets stuck on an old session. It’s supposed to save my open tabs and return to where I left off, but now, when I reopen Firefox, it reverts to the tabs from two days ago and no longer updates.

I currently have around 1,025 tabs open (I read a lot of Chinese online web novels). Bookmarks and history are still updating properly(when i click on history it still show the website i visited recently). The thumbnails in the tab list also display the correct version (the one I last used), but when I click on a tab, it reloads and goes back to the version from two days ago. i try to backup date on phone using firefox-android-backup-restore on github and saved as tar.gz . i can share that here if needed. what i could do to fix it except deleting firefox data. i don't want to lose all my opening tabs.
