I updated Firefox this morning to 139.0.4 on my Mac and now the '+' sign to add a new tab no longer appears on the tab bar. I can still add new tabs with Command T however.

Any suggestions on how to restore the '+' sign?

Thanks Dan

I'd like to ask about Firefox's behavior and settings. I'm using Firefox with vertical tabs (using an add-on), but it seems to be behaving strangely. The things that have changed since before are: 1. Open from pinned tab 2. Now opens in a new tab → Previously it opened in the same tab 3. Clicking on a newly opened tab opens a new tab again → Previously it would open pinned tabs/same tabs → in a new tab It has changed. I haven't changed any of my Firefox settings. Windows 11 Home 23H2 Firefox version 139.0.4 (64-bit).

When I middle-click a link in Firefox, it opens in a new tab, but it also switches me to that new tab immediately.

I’d prefer to stay on the current tab after middle-clicking, and just have the new tab open in the background just like google chrome does. Is there a setting to stop it from automatically switching?

Thanks!

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

every time i go to open a link it puts me in a new tab, even trying to use the original way of changing the preferences in the browser itself doesn't work, it either opens a new window or new tab. i dont like new tabs or new windows created while searching or opening links, please help :/

Hello, so I have been waiting for the Tab Groups feature and saw it should be available by the 6th of May, but after waiting, still no Tab Groups, I am not sure what to do or if there is a problem.

According to the most recent update page, this function should be working for all users by now. (see attached screenshot).

It is still not working for me. Has the timeline been postponed? Is anyone else still unable to use this function?

Thank you!

I am using Ubuntu 22.04. Firefox version is 143.0. IIRC firefox recently updated. I have the setting "Open previous windows and tabs" checked. Until very recently it has always worked but now when Firefox is closed all tabs are lost and don't appear when reopening Firefox. How to fix???

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.

My Firefox browser just updated to version 143.0.1. When the browser reopened, there was an instructional page that opened in a new tab describing the Unload Tab function. I followed the instructions, right-clicked on the tab, the drop down menu appeared, but there wasn't an Unload Tab option. However, there was a Reload Tab option shown.

How do I resolve this? I'm using a macOS 15.6.1.

Enter (paste) the URL into the Firefox address bar → hit Enter (paste and go) → open in a new tab every time. I want this to open in the same tab. Firefox version 145.0

Hi everyone Since sep-15, The "Open previous windows and tabs" function is NOT working .. everytime i have to reopen all the previous tabs. I am not sure if any update has caused this. Please help. Thanks

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

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!

I have an ultrawide screen, yet my pinned tabs only occupy 1/3rd of my screen width before you have to scroll through them. How do I make this area wide and allow more than 27 pinned tabs to be visible.

Hi, I have a large number of tabs and also have pinned tabs. When I click a link outside of Firefox (FF is my default browser) it always opens them at the end of my tabs (on the far right). I would prefer that the newly opened links open at the beginning of my tabs (the far left) but just after my pinned tabs. Is there a was to do this?

Thanks!
