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???

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

There is no longer a 'search tabs' symbol at the top section of the Firefox browser page since I switched to the vertical sidebar for tabs and after searching for help the Mozilla suggestion of ctrl+B just tries to search bookmarks. Please can you help as I have many many tabs always open and use this symbol frequently. Thankyou

I keep asking. I don't want to, but I am going to use another browser that I don't like, that does have the + as I keep hitting the y key to open a new tab. I am not well, cancer has me. My eyes are bad, and I could use some help, Thank you.

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.

Three days ago this started happening. When I mouse over the Firefox icon on my task bar, I get a long vertical list of open tabs, the majority of which are blank. When you try to click the X (that appears on the right side of the list when you mouse over a blank space) nothing happens. In the past few days it showed a random mix of blank tabs and open tabs. Yesterday it only showed the open tabs at the top with a long list of blanks below. And today it's only showing the one tab I have active (despite having up to five tabs open before I took the picture).

Before this all started happening, it used to show large tab previews (not just text) that run horizontally along the bottom of my screen when I hover my mouse over the Firefox icon on the taskbar. Now it's just a list that goes vertically with all these blank tabs.

How to return things to normal? (tab previews horizontally without blanks)

I'm running Windows 11 Home, Version 25H2, OS build 26200.7623 and Firefox: 147.0.1 (64-bit)

Thank you, John

I have read a Mozilla blog that you can make tab groups now, i have tried to make a tab group and it for some reason i can't, i looked at Mozilla's guide for the Tab groups, they didn't help. Does anybody know how to fix this problem?

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 seem to have accidentally set up tab-groups, on desktop. Probably I fat-fingered a shortcut to group some tabs. This is a function I'll never intentionally use — since I'd rather not cut off my fat fingers, is there a way to permanently shut off tab-groups?

Thank you kindly.

I have a strange problem and cannot find any reason for it.

On two different machines (with the same Firefox account, same extensions) I'm using tab groups, also in multiple windows (restoring them after launching Firefox).

In one installation I can close all tab groups without any problem.

In the other if it's the last open group, trying to close it (by clicking its header) opens a new, empty tab instead.

I'm pretty sure the settings of both installations differ but I cannot find any setting that would cause this behavior. It's especially annoying because with many open tabs I have to scroll through all to find the group I want to open instead, open it, scroll back to the other group header and close it.

Any pointers on where to start looking?

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).

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.

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

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!

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.

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.
