Maybe it is my spiritual guides because i obsses and have OCD and have too many tabs. But i started having tabs get deleted and i have no tabs on re-launch, tried to check, re-check this. I Am not sure if to reinstall because i don't want to lose passwords or setting/history (i don't remember now it should be saved) but usually reinstalling doesn't solve anything for me anyways...

I didn't install any new extensions when it started happening!

It doesn't happen every time so it is hard to troubleshoot, i cannot use browser with safe mode. I might test it couple times.

The new native tab group feature has an option to "Save and close group", implying that you can restore the group. But doing this, you will find that the group disappears.

Is this a known bug? Has anyone figured out how to restore a saved tab group?

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.

Until now I have always used the mouse scroll key to open links in a new tab in firefox. Now it does not work anymore. I have to right click the link and choose to open the link in a new tab. Have been looking for a setting for it, but can't find it. Is this something new? I want Firefox to work as it has always done sincce I started using it many years ago. Please help!

I have v138.1 and tab groups are not working. When I try and put one over another to create a group, it just sides away. I read this feature would be available on v137 and up after 5/6/25🤷🏼‍♂️

Running FF 138 64-bit on Win 10 Home, and tabs won't combine. When I move one tab over another, I get NO GLOWING RING, and the tabs just swap places as I move the first tab over the second one, no matter how slowly I move them. It doesn't work in Vertical Tabs, either.

Greetings...

I am a frequent user of multiple tabs whenever I use Firefox. As a result, the new Tab Groups feature interests me, primarily if it will help my to organize and manage my multiple open tabs. Initially, I have the following specific questions.

Q: Is there a maximum quantity of tabs that a Tab Group can contain?

Q: Is there a maximum quantity of Tab Groups that can be open at the same time?

Q: Does the use of one or more Tab Group negatively affect the performance of my web browser?

Q: Can a Tab Group be bookmarked? (Periodically, I need to bookmark a group of open tabs and I am currently able to do so by selecting all of the tabs then bookmarking them as a set.)

Q: Does the new Tab Groups feature represent a way to reduce the number of open tabs that appear at the top of my web browser - basically, a way for multiple open tabs to occupy a smaller space versus scrolling them across the top of my web browser?

Thank you very much for your feedback! Take care...

I have a couple questions on tab groups, I'm a new ms edge refuge but this not as smooth as I would like :). I realize tab groups are oddly new for FF, but I'm trying to get setup and running into two main issues. 1. I cant seem to freely reorder the tab groups, I can move the individual book pages no problem but not the groups as a whole. I would expect to be able to left hold click drag the order of the groups just like individual tabs. 2. Tab groups don't seem to exist across clients (or maybe I'm missing the how). If I open FF on my mac I would expect to see or at least be able to reopen the same tab groups as my windows PC, not just the individual pages from history on other device. Is there a way to do this? 3. can't import tab groups from edge? You don't want to make it easy for folks to switch?

Thanks, if I missed something happy to learn.

Because I was doing research for an essay, I had a great number of tabs open in Firefox. Today, I had to run a full-system virus scan, and now all the tabs are gone. Is there any way to recover them?

I have set the option to "Open previous windows and tabs" at Startup. But sometimes when I restart Firefox it starts out blank. Then I looked into how I could restore previous session but contrary to the article below, I couldn't find "Restore Previous Session" option under Settings/History. Please advise what I am missing. Thanks.

After updating to version 138.0, the browser put up an announcement page that informed me that I now have access to a great new feature, tab groups. It's actually a great addition to the browser IMO.

But it's absent. I read the announcement page, then the help page it links to. Every description is inapplicable to my browser, there us no drag-over behavior for tabs, there is no "add tab to new group" option when right clicking. I updated to 138.0.1, same thing. There is a topic in Connect.mozilla.org about tab groups as a beta feature, and it's been up in beta since March. But my browser does not have it.

Granted, the help page vaguely says that no all users will see this feature as it's rolled out gradually until May 6th. But why then tell me that I already have it on update? And why is it rolled out gradually if it's already been in beta?

I understand that as from 14th March 2025 I will need to update Firefox. I am currently running 102.0 and have sucessfully prevented Firefox from updating to later versions. I did this to prevent the updates positioning the tabs in the wrong place. Please can you tell me if the CSS script that I use to put them back into their correct position, i.e. below the Bookmarks Toolbar, will still work.

Also, will newer versions allow the user to choose where the tabs are positioned? It was possible to do this in earlier versions and the choice is also available in other browsers.

I have also managed to stop Windows 10 updating for several years too, Microsoft kept altering my laptop in unacceptable ways.

I found the tab groups more annoying than useful, so I went into about:studies and removed it, but doing so just makes a study entirely disappear with no way to bring it back if you misclicked, so that made me wonder, is removing studies permanent? Is it impossible to opt back in once you've opted out of a particular study?

I'm not particularly regretting my choice in this case, but it made me nervous how easy it would be to lose access to a feature just by accidentally clicking the wrong thing.
