im having issues with my tabs as there are now two sets of tabs one that is empty basically and seems to be treated as the main one and the other that is all my other tabs... but when i try to switch to them it switches my screen so other apps like games or messaging apps no longer are visible yet the still appear to exist

Please see this video. Double-clicking can only close the foreground tab. If I double-click the background tab, it will become the foreground tab, and double-clicking it multiple times in a short period of time will not close it. I have to wait about one second after stopping clicking the left mouse button before I can double-click it again to close it. Some Chromium-based browsers do not have this issue, and each of their tabs can be closed by double-clicking I can only show it with video. Please leave a message if you can't see the video.

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?

Hi, I want to make a simple extension for Firefox that auto toggles vertical tab based on the aspect ratio of the Firefox window. I found `sidebar.verticalTabs` in about:config that toggles vertical tabs, but a simple googling tells me that it is not possible for web extension to modify about:config values. Is there any other API that toggle vertical tabs? Thanks!

When I restart Firefox, or my PC wakes from sleep, my Firefox windows are all in a different order.

Also a number of Firefox windows often just die or don't appear on restarting Firefox.

Is there a way to make sure that the Firefox windows appear in the same order and number as before?

At the moment I have to close Firefox windows and start them manually loading tabs from bookmarks. I would have thought that there must be a better way but I can't find it.

It seems as if Firefox should number the windows and keep a list of tabs open in each window, but this doesn't seem to be the case.

What am I missing? Is there a setting I need to change?

I'm running Windows 11 Pro

Здрасьте дорогие разработчики

у вас есть функция, split-screen. Это круто! сделайте, пожалуйста, чтобы это могло включаться через контекстное меню(правая кнопка мышки), чтобы я навел мышку на ссылку и в контекстной меню выбрал этот пункт. чтобы я не через вкладки это делал, а через контекстное меню.

Hello, dear developers.

You have a split-screen feature. That's awesome! Please make it accessible through the context menu (right-click), so I can hover over a link and select it from the context menu. So I can do it through the context menu instead of through tabs.

OK - this keep happening on my firefox browser on my macbook laptop. I have a default firefox browser open with my 13 default tabs. Now when I have some app, like today specifically, the app for my voice caddy golf app. I open the app, do the update, and if I select any link that opens the voice caddy website, it opens it in a new firefox browser and tab, NOT a tab in my existing firefox with my 13 default tabs. So my default firefox gets trashed. In my firefox settings, I told firefox to open any new tabs in tabs, NOT pages. I also have open the last tabs open where I left off when I close firefox. What a pain. Tried several things to no avail. Why doesn't firefox have a setting (or the current setting do as I told it - open new websites in a new TAB, NOT a new browser.

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

TAB I am a new user of Firefox and when I open the browser today, I only had the use of one tab on each window. Yesterday, before closing for the night, I had multiple tabs. How do I get tabs so I can open multiple windows on each screen?

I recently decided to try vertical tabs in Firefox, and can't find a way to search these tabs as I could when they were horizonal, with the downward pointing arrowhead. If this is a feature, please let me know how to add it to my sidebar, and if not, it would be great if this feature could be developed. Thanks!

After today (Sep. 2, 2026)'s update, I noticed that the the plus "+" button for new tab is canceled. Instead, I have to now click right on the work function and click "New Tab" for a new tab. This revision is quite counter-intuitive. Could you please add back the plus "+" button for new tab in the next update?

Thank you very much.

I would really like to move from brave, but really need tab groups before I do so.

Its marked as progressive rollout. What exactly does that mean in terms of when I can expect to get this feature?

I have vertical tabs enabled and I'm trying to access the tab overview menu to close duplicate tabs. Unfortunately I can't find this menu anymore. If I disable vertical tabs, I can see the icon in the top right. How do

How do I access the tab overview menu when using vertical tabs?

Thanks

Hello,

I just found out about the Firefox group tabs feature and love the concept! However, on my computer (Linux, Pop OS), the default theme makes it difficult to see the underlining color for the group. Is there a way to increase the thickness? I've added a picture of how it looks, there is only a very thin (in this pic, blue) line underneath the tabs. I can barely see it, making it's use harder...

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.

I've got Reading the full Article on GROUP TABS that has been released yesterday on My Firefox it Got Update and Installed But I just couldn't found the "Add to the Group option when I click right at any of my tab" + If I drag over one on Another Tab it just got replaced like they substitute their Places No BOX Border line Shows No Group Created NOTHING. I'm a Nearly 6 Year Old Firefox User I NEEDED that FEATURE SO BADLY PLEASE FIX it SOMEHOW. ThAnks Regards: Loyal USer

I am using the Firefox browser version 138. However I am not able to use the Tab Groups from firefox. I cannot add any Tabs to any group as there is no option for that.

I'm running v138.0.1, but the ability to group tabs that was supposedly introduced in v137 is completely absent from my browser. I can neither drag tabs onto another to create a group, nor create groups by right clicking on a tab. What's up with that?

Hello everybody, Is there any way to revert unloaded tabs favicon revert back to slightly pale colored version like in 137 instead of non-colored b&w favicons.
