Firefox session open tabs gone after power outages

Aglae Pheryl · Jun 17, 2024

Hi folks,

Coming back from a week-end away from home, I noticed we had a few power outages.
Mozilla Firefox now opens with none of my previous session tabs (I had 4 or 5 browsers opened with 10-20 tabs opened for each one when I left on friday).
I'm having a hard time recovery these.
Any help appreciated.
Thanks

Couple things to try.

In the menu bar (press Alt to summon it if on Windows), History > Restore previous session

And main menu > History > Recently closed tabs/windows, there's an open all on each if you want to spam yourself with tabs.

If neither of these work and the main history doesn't help then there is not really a lot you can do unless you happened to have a backup of the Firefox app data directory.

Generally open tabs are not recommended for longterm storage across sessions.

Thanks. But I had tried this. Options are greyed out.
I found a 'backup' folder on my desktop that may have been created when Firefox got updated.
Pretty sure everything is in there somewhere.

I'll never understand this type of person. I personally can't stand having more than 4 or 5 open at a time or my anxiety murders me.

I merely find this more efficient and quicker, especially with harsh time constraints. Keep everything at hand (poor bandwidth also has a say)

That looks like a Firefox profile. You can find your current profile, create a copy for safety and then try pasting the backup contents to overwrite the in-use profile contents.

But as with any of this stuff, no guarantees.
