Firefox Community Forum

I realized today that my tab groups were all gone and I believe it is because I erased all of my search history about a week ago. Unfortunately I did not realize that clearing my search history would irrecoverably delete my tab groups, and I think it would not be intuitive for many other people either.

Ideally I would like to see a specific option to keep or erase tab groups when clearing search history but in the absence of that I think at least having a warning that you will lose your tab groups if you follow through would be very nice.

Please can you (a) add to menus, or create a button, so users can see the tab groups they have created and (b) prevent upgrades to Firefox from deleting a user's tab groups.

The Alt-<number> keyboard shortcut is used to switch between tabs. However, the key event used to switch a tab seems to also propagate down to the content itself. This creates weird interactions:

- I switch to third tab - The web page running in the third tab actually uses Alt-3 to do something - After switching tabs the web page does something unexpected because the browser chrome didn't swallow the event during its tab-switching procedure.

The most irritating candidate seems to be XenForo forum software that uses Alt-<number> to go to different sections in its menubar. For example, alt-4 seems to open a search page and going there provides no new entry in the browser history. So, if I've tab-opened the forum to display new posts and then later I switch to it using Alt-4, it makes the content go to its search panel with no way to go back to new posts. Ironically, switching _away_ from the tab 4 does not register to the content so I can't even use the forum's own keyboard shortcuts to navigate back to new posts section or any other section. Having the forum in tab X will only ever let the forum see Alt-X and nothing else.

This all stems from the fact that Firefox lets the initial tab-switching key event through whereas I think it shouldn't. It maybe should if the corresponding tab is already active but it certainly shouldn't when a tab-switch actually occurs.

I've obviously disabled the content's capability to override keyboard shortcuts but it doesn't help in this because the content is not overriding anything: it seems to be just listening to a keyboard event that it shouldn't see.

Did I miss some option in about:config or do others see this as well?

For about 10 days now the automatic tab reloader on Firefox doesn't work, it simply doesn't reload the tab. My up to date Firefox runs on the up to date Windows 11.

When I restart Firefox on my PC, many tabs in at least one window will be moved from their position. Usually to the end of open tabs within that window. I've been dealing with this for years and never heard a response from anyone else. It is very annoying as many of my tabs are set up in a sequence. I have to find the first one, manually select them all, and then use the command to move them to the start of the window.

I am trying again to see who else has experienced this problem and if there are solutions for it.

Hello, I went from being able to reopen Mozilla and have all tabs open. This stopped happening a couple of days ago. I do not have the restore previous session as was suggested to try when I searched this topic. I went into manage history, import and backup, restore, then selected the most recent date available. At first it didn't seem to work and I started searching through history to reopen tabs one by one. I left my computer (still running) came back and all my tabs had miraculously reappeared. I checked my settings to make sure nothing had changed. It hadn't - still set to reopen tabs when opening Mozilla. Closed the laptop last night, This morning - no tabs!!! I have a lot of tabs, and groups of tabs, with info I need. How do I recover these tabs and stop this from happening again? Thank you.

I started using a tab group to organize my tabs and save it. I was able to open it from the overflow menu before but now there is no trace of it there. Surely there is a way to see the history of tab groups and recover it right...

I've noticed for awhile that when exiting Firefox (currently 150.0.3) open tabs no longer close. When I re-enter Firefox (new start) I no longer get my home page. I've tried all key combination of exiting as well as the X. I searched this community and WWWeb and found nothing usefull.

Thank you for your attention to this matter. Rodney

Hello! I really liked the vertical tab panel management before, if I wanted it to disappear I've pressed ctrl + alt + z and if I wanted it to show only icons of the websites - I could press ctrl + alt + x twice and had the mini version of it. For some reason, now it's gone, when I press ctrl + alt + x twice the panel is gone completely. Could you help out here? Essentially, I want to be able to make it look like that (screenshot attached), only without the AI Assistant.

Perhaps I have missed a setting somewhere - while I like the concept of pinning tabs, I use the side bar to display my open tabs. If I choose to pin a tab, that tab is pinned to the top. Great. However, if I wish to pin 10 tabs, for example, they are all pinned in a single row. What I would like to be able to do is to stack them, maybe 3 per row, then have the 4th, 5th , and 6th form a second row. Is this possible?

All my Tabs Group have disappeared from the Tab Bar. I can see the Closed Tab Groups in the drop down but i can't find a way to re-open Closed Tab Groups. Any clues welcome. Running 146.0 and on the beta update channel.

I have MozillaFirefox-140.4.0-150200.152.207.1 on OpenSuse Leap 15.6. In my "Settings" under General and Startup I have always had the option "Open previous windows and tabs" checked.

This just started happening recently. After the first time it happened, I restored everything by searching through "History" and recreating the tabs and windows. Everything seemed OK for a few days then it happened again.

Por algum motivo, meu firefox está abrindo conforme a página inicial configurada, contudo, sempre deixei para retornar com as guias que ficam em aberto e por algum motivo, meu firefox bloqueou a opção de abrir já com as guias da sessão anterior.

Não sei se é coincidência, mas está acontecendo após esta ultima atualização (19-05-2026), alguém mais está com este problema?

Minha alternativa será abrir minhas páginas todas novamente, e configurar para o firefox pegar as URLs como pagina inicial padrão...

Can you enable members to pin there folders and pages in the bookmark bar so that it looks neater and can fit more pages and folders etc, even multiple pages and folders together same as the tab bar,

also allow more power to open and use more tabs at the same time upto as many as will fit on page, 50?

i use manual traffic exchanges, which i have to surf and change tabs regulary and faster to surf more manual traffic exchange websites, we need this to build up free advertising credits to promote our programes and business opportunities.

Also can i add all my GMAIL, yahoo mail and notepad accounts together in 1 fixed pinned dropdown tab instead of using up multiple tabs.

So, I've just went on a quest to find a solution to my pinned tabs disappearing every few days, and it seems like this can happen if I don't shut down Firefox properly. Is there a way to stop this from happening?

That's my question. The rest of this is curiosity about the issue since it's seemed to have persist for a few years:

Is this intended behavior? No other browser I use does this and judging from the hits I got here, and elsewhere, it seems undesired. Is there some security or privacy reason it's like this?

I know I can repin the tab, or take some session recovery steps, and a few other things... but IMO, those are workarounds, not solutions. Barring some technical or mission limitation, a true solution should prevent this from happening at all.
