Firefox Community Forum

in FF 137.02 Win11Pro there is no reopen previous session option in the history menu, even though in settings, history, "firefox will" is set to remember history. We tried reinstalling FF. No luck.

Is there a way to reopen the previous session?

Has that feature been deleted?

Suddenly Firefox has started losing all my tabs when I close Firefox. It never used to. Windows 11 I have checked my settings - they are all as they are meant to be to NOT do this so why is it doing it????

I have a new computer and I installed Firefox and when I open Firefox, my previous session tabs are opening, even though the "Open previous windows and tabs" is NOT checked.

Hello,

There's a way to recover a pack of history that I left open, but I've put another station open together and closed the old one first, and now I've lost a lot of tabs that were open. I don't know if Mozilla has that function, but that will be great. Something like that saves me a lot of times in Chrome, but I want here. Mozilla is better

I don't fully remember when this happened, but lately the browser has trouble clearing my search history even though I had it set so that it does so every time I close it. I only managed to fix it by making it so that it doesn't remember the search history, but some of the old searches are still there whenever I punch in part of what I was searching.

by jump to specific history, I mean something like search in library > bookmark and right-click on specific link then "show in folder"

it would be very helpful if something equivalent of "show in folder" exists in the context of history search, I often search specific site and wondering what else sites I opened around that time (relative to specific site I found on search results)

if there's any workaround or alternatives, please leave a comment! ^^

The sidebar on Firefox seems to have updated with a sidebar that looks different and only allows history searching by date OR site. I regularly access websites quickly through the old sidebar style that allows sorting by date AND site. Is there a way to get this back?

Anytime I close out Firebox all my tabs and history are gone. Even if I make tabs it keep being deleted. This happen recently after I sync with my steam deck. I didn't touch my setting recently, Firefox should auto-update so it good, and my account is safe. I don't know what is happening that can caused this bug and only thing that I find is weird is having two same account on my deck and not my pc. Only thing I can think to fix is to uninstall Firefox which I will try later.

Hello.

My name is Connor, and this morning i fear i made a dreadful error. i was about to open my mozilla, with the session (tabs and windows from yesterday 08.04.2025. included). as i was launching my mozila it froze, so i closed it and ran it again. but when i did i lost everything i had up until yesterday. is there any way i ca get it Restored, or is it all gone forever?

P.S. i don't have a phone due to my physical dissabilities. so if possible please contact me via my email.

i apologize for the inconvenience

My setting for "Open previous windows and tabs upon startup" is no longer working. It always used to, for years! Now whenever I launch Firefox, I only get a single, fresh tab.

I'm on a 2017 Macbook Pro. I believe I was using Firefox 137.0 but have now gone back to the last saved update session file which is 133.0.3.

When I close Firefox, it clearly recognises all the open windows as it asks if I want to close all 6 windows. When I reopen Firefox it briefly shows all the windows in position but before it reopens all the tabs in those windows, 2 of them disappear. If I open a new tab and start typing something I know is in those missing windows it suggests "Switch to tab". If I click on that the current window dulls as if the requested window and its tabs have become active but the entire window is invisible. I have tried renaming xulstore and localstore and tried deleting xulstore entirely. Neither worked. It's possible that I hit some mental combination of shift, command and something near the 3 or 4 keys on the keyboard as I was trying to take a quick screenshot on a website before a pop up reappeared. This was the last session where everything was as it should be. I wish I hadn't gone back to the saved update session from December as its clear the app still recognises the windows are "there". I've reopened it so many times since having deleted tabs, cookies, whatnot that the session I was in before things went pear shaped is now long gone. If I click on the icon for recent browsing it shows 6 windows and I subsequently deleted some tabs from the missing windows that might've been an issue, were recent, or might use more power like Youtube or news sites. On restarting, the 2 missing windows remain invisible. In the words of Penelope Pitstop. "Hayulp!" Any guidance or tissues gratefully received.

I like to use mozilla having several windows open. I don't turn it off in the standard way, I just turn off the computer with all windows open. When I turn Mozilla back on, all the recently closed windows open for me. I remember that it was enough to change one function in about:config.

Since the latest stable update, I have not been able to shift click or control click multiple entries on the history tab to delete entries.

I have to click the trash icon on each item now and its very time consuming.

Is this on purpose? is there a setting to revert to the old way?

TIA
