Firefox mobile closed nearly all my tabs

I had something like 50 tabs open on my phone in Firefox (not all were always loaded, I kept them for reading them later) and a few minutes ago, as I opened Firefox, suddenly there are only 2 tabs open, which are the ones I opened today. Of the other tabs there seems to be no trace. When I tried opening the synced tabs window on my PC, it briefly showed the lost tabs for my mobile Firefox, but then synced and thus also showed only those 2 tabs from today (should've removed the ethernet cable before...). Is this normal behaviour for Firefox? If so, what's the reason for it? If not, what can I do to prevent it?

there may be a backup sqlite database of the crashed session with 50 tabs in your user data.

i would suggest bookmarks as a slightly more viable option, although "groups of tabs" appears nonexistent in mobile and deprecated in ff desktop last i saw, iirc.

apps may corrupt such things as sessions, although it may be the infuence of other things happening in the device, or in one of the tabs. i don't know that random computational barfing is preventable, in my years of experience. i don't believe it would be an intended behaviour in ff.
