Hey there, I had two windows in firefox open, one of which had a lot of tabs. I was using firefox on my surface pro, and then got up to get a snack. I came back, and the window, which I had been using for some time, was gone. The other window was still open, and firefox had not been closed. I thought I would just open it up by restoring recently closed window, but it was gone. I routinely clear my history, but even tabs that I just had open 5 minutes ago are missing from my history, like I never opened them in the first place. What is going on?

I love Firefox and generally really appreciate the way y'all operate as a company and developer.

However, I really don't like this new function to add tabs to a group. Since it rolled out, I'm always adding tabs into groups when I don't mean to. Really, it's creating a group almost every time I move a tab around. If I delete the group, it's just more clicks and distractions to deal with.

In the past, when you've rolled out new features like this, you've also made it very easy to turn off any new feature we don't like. But I can't figure out how to turn this off. Is it possible?

Thanks for your help.

Hyperlinks keep opening in new windows, not in the same/existing window where they were selected. Issue is not unique to Google Search results and occurring across multiple websites. At wits end trying to figure this one out. I have deselected the "Open links in tabs instead of new windows", turned off all extensions, and uninstalled & reinstalled Firefox. Issue is still occurring. Attached is image of my tab selections showing all turned off.

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.

The AI tab thing is a problem for me for multiple reasons. I found various articles about how to turn it off. They pointed to the following setting: In about:config set the setting "browser.tabs.groups.smart.enabled" to false, and then restart Firefox.

However, when I do that, and then immediately go back to about:Config to check the setting, it has changed itself back to "true".

Other settings accept and keep permanent changes. This means that I'm not forgetting to save the change or anything. Just this one setting (which turns off something causing me problems) refuses to actually stay set.

I see the answer to this question https://support.mozilla.org/en-US/questions/1509077 and tried looking there. There is a completed study called "Smart Tab Groups Rollout", but since it is in the "Completed Studies" group, I cannot remove it.

Due to not everything reloading every time, a connectivity problem I can't blame Firefox for, I now have 3 windows, together comprising all the tabs I want [OK some are duplicated, but it's easy to remove those...]. How can I stick those all back into one window? - with my pinned tabs at the head., which is where they were before...

For some reason, though I have changed absolutely nothing with my browser, now any time a link is supposed to open automatically in a new tab, it opens in an entire new window. My mouse only has two buttons (Magic Mouse on Mac), so there is no way at all for this to be user error in that regard. The best example is in Gmail when you have multiple accounts signed in, you click the profile picture in the upper right and select a different account which then opens in a new tab. I notice that when I use a fresh profile the issue goes away, and migrating a copy of my existing profile between different Firefox versions (this profile I use in 115 ESR exclusively, I don't use it with more than one version, I just mean for testing purposes here), including forks like Waterfox, all are affected by this issue. Is there something in about:config I should look for to change?

Hello, When i create a new tab (cntrl + T) I can no longer just start typing and have that be a google search. Now I need to manually click in the search bar. Is there a way to enable it so creating a new tab automatically puts the text into the search bar field?

Not sure why this stopped working, maybe a recent update. Thanks for your help.

Good morning, I'm running Firefox Developer Edition 143.0b6 on Linux Mint 22.1. A couple of weeks ago I noticed that when moving tabs on the left-hand side they'll instantly get locked into an inscrutable and seemingly impossible to fix "pinned mode". Is there a way to turn this off? It is driving me crazy. I've looked through Settings > General > Tabs and about:config and didn't see anything relevant. If anyone has run into this or knows a workaround, I’d be grateful to hear it.

tried all suggestions - not pinned - closed properly by using exit from settings on RHS, etc FF used to work great for several years - then mozilla updates (something) and *ucks it all up And I do NOT want to work for Mozilla, testing their browser all the time

I have a fresh installation of xubuntu 24.04, with firefox 135.0. Middle clicking on links now does nothing, whereas earlier it opened the link in a new tab. browser.tabs.opentabfor.middleclick is set to true.

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!

I often hit ^T (control-T) in firefox without meaning to, because I use that chord in other applications a lot. In firefox it opens a new tab, which is almost never what I want. I'd like to suppress that keyboard shortcut. I tried doing it using vimium (unmap <c-t>) but that has no effect.

Thank you, Silvio

After my Windows 10 laptop being in sleep mode I found my background picture changed and all my Firefox tabs missing (while my bookmarks, add-ons, history etc. saved, and all other apps functioning properly). Recently Closed Windows menu was inactive and using Restore option in Library had no effect (despite availability of recent saves).

I found out that Mozilla folder was just missing in %appdata% (e.g. Profile Folder in about:support leaded to a non-existent directory). No manual changes to Firefox settings/data were made and no new profiles created.

What might be the problem and are there any ways to restore my tabs?

When I search a subject from Google, I want the search tab to remain, and for a new tab to open when I click on a link. I don't want to open the link through the same search tab.

After researching, I tried to go through about:config and I changed the browser.search.openintab to 'true' but when I search it opens through the existing search tab.

I hope I am explaining this coherently. Can someone please help me?

I have recently switched computers, and since it has been a while, I can't remember the setting on the 'about:config' page that I need to change to where when I open a new browser tab, it opens at the end of my list of tabs, rather than as the next tab. Thanks!

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.
