I was excited to receive the new Tab Groups feature and am now disappointed that it's not working and I've 'lost' dozens of tabs.

Here's what I did: I created several groups by right-clicking and added tabs to each of the groups. Since it appears that only way to collapse a group is to "save and close group," I closed each group. Now they are all gone. When I right-click to create a new group or "add tab to group," the closed groups are nowhere to be found. Plus, I do not see a "list all tabs icon" on my toolbar to reopen the grouped tabs, which is what [article] says should happen.

Suggestions for making this work?

The mute tabs icon is just a waste of space as soon as you get a few tabs loaded and the tabs shrink. I have multiple tabs showing at the moment where I have clicked on the icon and unmuted them when just trying to select them. It does not help that the icons have been placed in almost the exact centre of the tab, at least with the 19 I have showing in a mix of muted/unmuted. Only 7 of these tabs are still muted, although I did deliberately unmute one to check the action.

I would prefer it if these icons are not showing as they are a waste of space and my time. If you hit the icon the tab is not brought to the front as intended so you have to click on them again. I just want the tabs to work like real tabs.

Is there any way to remove the feature altogether? I have after a lot of frustration just reduced the sound for Firefox in the Windows Volume Mixer as I did before tab muting was thought of. I almost never use sound in Firefox anyway.

I have lost my tabs after the recent update. They used to show all tab groups in toolbar icon as mentioned here (https://support.mozilla.org/en-US/kb/tab-groups) in manage tabs section. Only the groups that were open are retained, the groups which were closed are lost. They contained important tabs which I haven't bookmarked. I didn't see any policy of removal of inactive tab groups after certain time, any help would be really appreciated. I use the desktop app on Linux.

1. 1. Steps to reproduce

Open several tabs, in settings, check «ouvrir les fenêtres et onglets précédents», quit firefox.

On startup, Firefox should reopen with the same tabs before shutdown.

Firefox opens with one empty tab. Forcing me to got to «history -> recently closed windows -> restore» everytime I quit Firefox or shutdown the mac.

Hi, I have the settings of 'General > Startup > [checked] Open previous windows and tabs' on. Most of the time it works as expected, but there are several occurrences when all of the sudden all of my pinned tabs are gone. When this happened, I usually tried the 'Command + Shift + T' to restore them. Sometimes they came back, some other times, they don't.

Can you fix it?

It's starting to get really irritating because I can have >12 tabs pinned and it's troublesome to have to remember them all in case this happens again in the future.

Thanks!

Hello, I've been using Firefox for several years because of all browsers it's the only one (I know of) that has a setting whether to open links in new tab or in new window. I want them opening in tabs. This has been quite alright until last week when I was suddenly shown a message that I was using an old Firefox version and was forced to create a new profile. I did that but ever since then links keep opening in new windows - even though I have found the relevant setting and ticked the box "Open links in tabs instead of new windows". With or without the box ticked, the only way to open links in new tabs is to simultaneously hold Cttrl and click on the link. I've tried all variations of this box and the next two, but no luck. This is really important for me. What am I doing wrong? Thanks!

Recently Mint upgraded my FF to v147 - possibly relevant, possibly not. There's no post mentioning anyone having this issue on the Mint forum though.

In my Settings, "Open previous windows and tabs" is definitely enabled, but it doesn't happen. I only get my homepage custom URLs.

I went into troubleshooting mode and FF then behaves.

So I figured the issue must be with an extension - but I disabled all my extensions, and it doesn't help. Only going full troubleshooting mode fixes it.

What do I do next please?

I just opened Firefox on my Win 11 pc, and find all my tabs have gone. The setting to reopen last session is active, as before. I think FF updated itself earlier today. I also had occasion to look at it briefly on my synchronised android phone. I would like to: - get my tabs back - find a way to stop this haappening (it's not the first time).

Any advice much appreciated, thanks. Richard

Firefox crashed. I am trying to get it to how I had it before this. One of the problems is the new tabs thing. I know about CTRL-T, I have not used it. I have used the + on the tabs for years. I know, big deal, it's just inconvenient, interrupts my train of thought to switch, which is no big deal. But if anyone has a moment and can answer, it would be a blessing for me. Thank you.

Hello. I love the feature. I didn't know it was a new feature because I started using Firefox around April. I saved my group tabs, very happy about it. Then I close and save it, then I opened it again, it was great!

I am a student, I use my group tab to add the tabs that have the resources that I need to, and would also like to study for more knowledge and for my next school year.

There was no problem at that whole time. In April 21, there was no problem until April 22, 23 no problem. But I forgot my charger at that time, because I was at my mothers house. Then I wait for weeks for my charger to come back, about 2 weeks for my laptop to revive there in my grandparent's house.

When I got my charger, and opened firefox. Wait, but at first when I opened firefox, it showed me that there is a new update, an update about tab groups that I already now. I looked at my group tabs, and they are not there anymore.

What should I do to get them back.

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?
