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.

Middle-clicking a link used to open the link in a new, background tab. This suddenly stopped over the long, Memorial Day weekend.

I know I can just Shift-middle-click to get this functionality, but if you're (Mozilla) changing the default* functionality, I would assume you provided a way to go back to the old style.

• I may have changed a setting years ago to make middle-clicks open in the background, but if I did, it was so long ago that I don't recall. Regardless, did that option go away after some update?

I noticed this today. I updated both Windows and Firefox and tried again with the same result. This works as I intend (middle-click opens links in new, background tabs in Chrome). So, this isn't a mouse driver or hardware issue.

Hi,

In my Firefox Developer install the new tab groups feature seems to now be working like one would expect, but my main Firefox install (Firefox desktop 138.0 (64-bit)) has some issues.

I can add tab groups, add tabs to groups, but left mouse clicking the colored tab header does NOT close the tab group, like it does in Developer browser. Mode of tab group clearly changes, as the tab is either dark or light colored after a mouse click.

I don't remember changing any other settings lately in about:config, except setting tabs.groups feature to true, and I don't have too many extensions installed, and I also tried disabling all the extensions, but that didn't help.

I can't re-open a saved tab group. I saved it and closed firefox but when I returned I couldn't find where to access it. I see all of my saved tabs when I right-click on a tab and choose "Add Tab to Group", but when I move the tab to that group it just disappears rather than open the group. Any help would be appreciated! :)

Hello, I have Firefox set to open the tabs that I had open during my last session. (General > Startup > Open previous windows and tabs). When I open Firefox, it does give me all the tabs that were open in my last session. But it does not give me the current pages. It gives me the pages as they existed when I closed it.

Is there some way to have Firefox refresh the tabs when I open the browser? I seem to remember this happening in the past. But it's possible I was using a different browser then.

Now I'm using version 133.0.3, Firefox for Linux Mint mint-001 - 1.0. Yes, I realize this is not the current version. If it's possible to get this feature with the current version, I'll be happy to upgrade.

Thank you very much.

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!

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.

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'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?

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

Hello All!

I have recently tried to use Firefox View button in order to quickly open pages that I have opened on my Android device, however I found that only some (random) portion of the tabs appear in the Firefox View under [tabs from other devices/my android device].

Is there any way I can change that behaviour? This is renedring the Firefox View kind of pointless, as I still have to open my phone to check whether there was maybe one more important page that I wanted to check out, that was not listed in the Firefox View on my PC. At that point, I could very well just see what were I at, on the android device, and just google stuff again. The mixed approch (some opened via Firefox View and some manually) is more time consuming than either of the approaches alone, so I would really appreciate help, as Firefox View seemed to be a time-saver - I believe I have something set erroneously somwhere. Thanks!

I am on firefox 125.0.3. 64-bit.

I recently updated to Firefox 138.0.1 to use the new tab groups feature, which allows grouping and labeling tabs, as outlined in Mozilla’s support article (expected for all users by May 6, 2025). However, after updating, I don’t see the tab groups option when dragging tabs or right-clicking them. Has anyone else faced this issue? Could it be due to the progressive rollout, a conflicting extension, or a setting I need to enable? I’ve tried restarting Firefox and checking the tab bar, but no luck. Any community solutions or workarounds to enable tab groups would be greatly appreciated! Please share your experiences or fixes.

I've set up a second profile to keep my personal and work browsing separate. When I reopen my non-default profile, it doesn't restore the previous session's tabs. I have "open previous windows and tabs" checked under Settings > General > startup in both profiles. Please advise.

There are many tabs open in the firefox window. I'm closing the firefox. I'm opening it again.All tabs opened during the previous opening disappear.Either a new page or a single tab opens. The settings are set to "Open previous windows and tabs" (Image 1)

I go to "Firefox View" ---"Open tabs". (image 2) I see 2-5 windows there.In this case, there are 3 windows.WINDOW 1 is my main window with the tabs that should have been saved and opened when firefox was launched again. I close all tabs from unnecessary windows with a cross.Only window 1 remains. But when restarting, an empty or different window opens again.And again, there are a lot of unnecessary and incomprehensible windows on the list. Previously, a window with restored tabs from the previous session always opened. Question: 1)How can I restore the normal recovery of the previous session when restarting? 2) Tell me.I can somehow switch between windows (Firefox View" ---"Open tabs)(Image 1) Thank you.

So I change the tabs maxim length (i chose 225) because i hate not seeing the name of the tabs that i have open, now i have 10 tabs on my sight on my monitor, i usually open a LOT of tabs for youtube videos or so on, and have a constant of 40+ tabs open

the issue is when i scroll through the tabs with my mouse wheel, it jumps 10 tabs at once, now i see the arrows on the side of the tabs, my monitor is Ultra Wide so is annoying to keep pressing that Scroll backwards & Forwards button especially when the speed is to slow, while my mouse wheel speed is in 10 tabs TO fast!

Is there a way to change the Speed of the mouse wheel scroll tabs ? something in about:config ? or a Add-on?

Note: Please read my reply to the post, below, for an update.

I like to have new tabs open at the end of my tab stream so that each new tab opens in consecutive order. This is only inconvenient when I have a lot of tabs and need to scroll to the end for the latest. Because I was working with a lot of tabs today I toggled the following to "true" in about:config —

browser.tabs.insertAfterCurrent = true browser.tabs.insertRelatedAfterCurrent = true

The issue I'm having is that after toggling back to false, new tabs continue to open after the current tab, rather than at the end as before.

I'm not clear on the difference between related and unrelated, so I've experimented toggling one on, one off and neither or both but for some reason the behavior continues to default to opening new tabs after current in each case.

I have also tried restarting both Firefox and the computer, but this has not had any effect, either.

I have included a screen shot of the present settings and behavior.
