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...

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 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!

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?

OK after the code breaking yesterday here is the new code I got that works.

Are tab groups like containers i.e. isolated from the others, so thay I can access sites logged into different accounts for instance or separate browsing experience/cookies ?

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

If you have a legitimate question, please start a new question at /questions/new with details.

I'm using Firefox Developer Edition v136.0b5, and I'm looking for a way to remove “Turn on Vertical Tabs” from the contextual menu, because I'm so used to reopening a tab by clicking on what was then the last item in the list, that every time I end up with vertical tabs lol.

This code in mozilla.cfg used to overwrite new tab, but as of latest firefox 136.0b1 no longer works. Any way to fix this? There error in Browser Console.

// mozilla.cfg needs to start with a comment line var {classes:Cc,interfaces:Ci,utils:Cu} = Components;

/* set new tab page */ try {

 Cu.import("resource:///modules/AboutNewTab.jsm");
 var newTabURL = "file:///D:/Documents/images/home.html";
 AboutNewTab.newTabURL = newTabURL;

} catch(e){Cu.reportError(e);} // report errors in the Browser Console

This feature has suddenly appeared and I absolutely detest it! I don't need it, don't like it, don't want it! I have searched everywhere on how to disable it. PLEASE tell me there is an option to do that.

Firefox has a feature where, if you select a tab and drag your cursor downwards while still pressing down on it, it will open that tab in a new window. Is there any way to disable this? I am frequently opening tabs in new windows when I'm just trying to view them and it drives me mad. I never use this feature intentionally- I am constantly using on accident due to quickly moving my cursor away from the tab bar to view the tab I just opened. Thank you.

I used to be able to drag a tab from one window to another. Has this facility been removed? The Move option lets me move the tab to Start or New window, but not an existing window as I would like.

Hi Was told to ask new question off of this tread. https://support.mozilla.org/en-US/questions/1314940#question-reply

I have similar issue. Have file that has all the tab history, but can't get Firefox to recognize or use it. The scrounger pulls up everything so the file is good it seems.

Why can't, or how do we get Firefox to use it?

Thank you

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.

Hi firefox community,

I am using Firefox version 127.0.2 as my main browser on MacOS Sonoma 14.5. For the past few months, when using Firefox in Mac's full-screen mode, I've been experiencing an issue where one of the multiple open tabs unexpectedly displays in a separate window the moment I click on it.

This behavior didn't occur previously, and I believe it started happening about 3 months ago. It doesn't happen every time, but occurs a few times a day when I least expect it, making it difficult to identify the specific conditions that trigger it. I use a Magic Trackpad, and after switching to full-screen using the three-finger gesture, the moment I try to activate a specific tab, that tab alone displays as a separate window in full-screen mode.

Is it possible that a Firefox version update has changed this behavior? If this is a Firefox issue, is there a way to capture debug logs to have the developers investigate it?

Alternatively, if there's an option to prevent tabs from opening in new separate windows, that would be an effective workaround. Could you please let me know if such an option exists?

Best regards,

Since the last Firefox update, I've noticed an issue whenever I launch the browser. I have it set up so that I have multiple tabs open, and it's set up so that when Firefox starts up, it opens all of the previous tabs and starts me on the tab I was on when I closed the browser previously.

Now whenever I start Firefox, it opens to the last tab I was on, but said tab opens on my current homepage instead of the website that tab was on previously. I experimented by changing my homepage to "Youtube.com", picked a different open tab, closed Firefox and opened it again and sure enough, the tab was now on the Youtube page instead of what it had been previously.

Is this just a bug of the current Firefox version, or is there something in settings I can do to fix this?
