Firefox version 145.0 in Linux Ubuntu 22.04.5 LTS. When I open Firefox all tabs from previous session are gone. On "Startup" I have checked "Open previous windows and tabs". Which worked before but not now. It is very frustrating. How do I fix? The Profile Manager opens the settings and "Open previous windows and tabs" is checked. Checking "ask before closing multiple tabs" doesn't help.

I've just updated Firefox to 136.0 and found the "return closed tab" key became blank and ineffective. I read the update log but didn't find infomation about this change. The function was useful to me and I hope to get it back.

I have the most recent update and have been excited about tab groups, but it's still not working on mine. I thought the update would be available to all as of May 6, 2025. Is this happening to anyone else?

My old hard drive died I couldn't recover it. I cannot mount the disk to another OS etc. The session files cannot be retrived. However I had over 100 tabs open in Firefox I want to retrieve before the disk crashed. I was signed in to firefox all the time in the old computer.

I now have a new computer, I signed in to firefox and I can recover the bookmarks. But I don't see any option to recover the lots of tabs and sessions from my previous dead disk. It seems there is tab sync options between 2 devices that is concurrently signed in. But I can't sign in to a dead disk. I also can't recover the file.

How can I reteive my old sessions with many tabs? I'm hoping firefox have a way of knowing all my tabs since I was signed in and sync before the disk crash.

Hello, I am using Firefox on a new computer, and I have a bizarre problem that I never experienced on other computers. The 'recently closed tabs' and 'recently closed windows' options are disabled. They are grey, and I can't click them (see image). Also, the 'reopen closed tab' when you right-click one of the tabs is disabled (grey). I have tried to search everywhere why it can happen and found nothing. Any advice on how to enable this option? Thanks

How can I move a tab to an open window? I know there is a function in the pull down menu to open the tab in a new window, but I would like to move the tab to a window that is already open. Google and Brave Chrome have a seamless, easy way on the pull down menu. I use it all the time, but I want to keep Firefox as my default browser. Thanks!

Hi. Yesterday something weird and unexpected happened to my Firefox and amongst other things it lost all my open tabs, of which there was about 70 or so. Another strange thing which happened is a website I use turned into Japanese language all on its own and in the end I was forced to delete cookies for that website to revert it to English, even though it was never changed in the first place. My homepage shortcut tiles were also all rearranged and some deleted. I have no idea what caused all this, but the biggest issue for me is that I lost all my open tabs. I refreshed Firefox to try to cleanse whatever it was that caused this, but even before this I lost my tabs.

My question here is; I am sure that the history of those open tabs is still listed somewhere on a file and I can get back my previous session which had all the tabs on it, but I have no idea where it is or where to look. How do I do this and where do I find the older file with the open tabs.

Thanks.

the tab groups feature doesn't work. WHen i drag one tab onto another, nothing happens, other than the tabs go back and forth. Can't put one tab over another and no group is created.

Sometimes drag functionality stops working. I can't grab a tab to move it to another position or to a new window. (Holding left click on the tab and moving the cursor does nothing). Also, re-merging the tab with another firefox window stops working. (Dragging a tab to a firefox window from another firefox window doesn't merge them. It does nothing) I can right click on the tab and select Move to move it to a new window but dragging stops working. I have to close Firefox and start it again (sometimes twice), then dragging starts working again. This happens multiple times a day. I am on Linux Mint and the version is 126.0 (64-bit). This problematic behavior has only recently began.

In early June 2025 I finally ditched Windows 10 for 11 and I've been a Firefox user since practically the very beginning of Mozilla.

Now, I notice that the "Restore Previous Session" button in the drop-down of the FF menu is missing. Additionally, I discovered late in the game that Mozilla DID listen to me and gave us the ability to "name" or "tag" an entire window in the browser. This was a HUGE boon to productivity as I'm constantly toggling from window to window to tab to tab.... Now, with the most recent update this ability seems to have disappeared....

PROSZĘ zróbcie czułość rozwijania bocznego panelu. Nie wiem czy to tylko w ostatnim czasie ale bardzo ciężko najechać na coś kursorem blisko bocznego panelu ponieważ ten odrazu się rozwija. Jestem zadowolony z tej formy kart przeglądarek więc chciałbym przy niej pozostać, natomiast ta czułość rozwijania kiedy kursor myszki jest stosunkowo daleko jest irytująca i znacząco utrudnia korzystanie z przeglądarki.

Why won't Firefox open any new windows? I give ir the command to open a window and yet all i get are tabs and I never click on open a tab. I have an HP probook this for windows 10 and i am also having the same problem with Chrome. I have uninstalled and reinstalled chrome and that did not fix it so it is not that. What would cause this? I have already cleared the cache cookies history browsing etc. and nothing is fixing it. PLEASE HELP.

Hello, I used to have Microsoft Teams as a pinned tab (in fact I think it was my first pinned tab), which I no longer need as I now have the Teams app on my computer. I have tried unpinning the Teams tab but whenever I close & reopen Firefox, it reappears - it doesn't show up initially, but will pop up 5-10 seconds after Firefox starts (my other pinned tabs show up straight away) - so I have to close it each time. Not a big issue I know but kinda annoying - any suggestions/solutions?
