Firefox Community Forum

7/7/2026 Last night Firefox on my laptop performed an automatic update to the latest Firefox version. The new Firefox has a very bad setting in about;config .. this new Firefox can only show 1 tab ... it is opening up a new tab on top of the first tab, making it impossible to have more than 1 tab ..

This is going cause problems for thousands of Firefox users .. . how I fix this problem ... I tried setting the add tab settings into about;config to add a new tab to the right of the current tab, but my change made no difference ... how can I fix this problem ... does Firefox have a plan on how to fix for this problem for thousands of Firefox users.. this problem will impact thousands of Firefox users..

You seriously need to remove the AUTOMATIC tab grouping, it's annoying as hell!

I know there's a workaround, but that's beside the point. You don't break into someones home in order to re-organize it, that's just bad practice all around.

With vertical tabs and expand on hover, clicking on the X box rarely closes the tab. Sometimes I have success if the pointer is on the left or right line of the box. Not having luck on the center of the box. Has been true for several weeks. With hover off, clicking the X works fine. I am running Windows 11.

Firefox recently started "eating" my tabs: closing them without my permission. There are several tabs I want to keep open at all times, because I refer to them from time to time throughout the day, but Firefox closes them from time to time. I googled the issue and the AI directed me to two settings: browser.tabs.unloadOnLowMemory and browser.tabs.min_inactive_duration_before_unload. It suggested setting the first one to "false" and increasing the duration of the second, or setting it to "false." However, the setting will only accept numeric values.

Since I am not having low memory issues, I want Firefox to leave my tabs alone. Is there any way to actually do this? If not, it would be really nice if Firefox developers reversed this intrusive change.

Thank you, Terry

I want the browser's tab bar to display like the homepage, instead of disappearing after opening a webpage tab bar. I don't know if I can accurately express my meaning, but I will attach two pictures

The setting works...in the way that if i quit Firefox, it'll not continue from the tabs and windows, but if i reboot my pc and open Firefox, I find myself the same place i stopped...even though i have that setting disabled. I found someone else with same issue on reddit and i did the same restarting the browser and refreshing and all....all to no effect.

I use Windows, and my browser is already set to open windows and tabs and to automatically open Firefox on startup. My history is set to Remember History. I've tried using Ctrl + Shift + T with no luck. What else can I do to get this function back?

sense I leave tabs open that I want to watch latter i would like to be able to see the video before I close the tab: when i open it says the tab that is taking the most memory is "https://youtube.com (15668)" I tried clicking and right clicking but no functional it locate or go tab then i opened the drop down the search bar set it to tabs and typed in "https://youtube.com (15668)" but it showed no results.

Hello,

how can i disable firefox usage hints like "Try tab groups for less clutter, more focus"?. It opens up if i open up a certain amount of tabs. Is there anything i can disable in about:config?

Thank you.

[I use firefox on Mac, Windows, and Android, but the issue seems to effect me mostly on Mac and Windows) I'm just guessing this to be a browse issue. However I won't miond the post being moved to a more relevant sub-forum.

I keep arriving at this solution when searching for a solution to the increasing number of sites using the irritatingly abused stay/leave page question-dialogue box which pops up when i want to leave a page. The common solution appears to be https://userscripts.org/scripts/show/23865 However, when this page loads, I just get an empty box which looks like one of those ones which normally contain scripts to run or stop running certain things, or even to add or embed items etc.

When researching I often need to load lots of pages top go through. however, when i then need to close them all, i end up manually having to complete these irritating dialogies which are OBVIOUSLY really meant for pages where you may be filling in a form, or editing something, and perhaps have not completed filling it in. However, many sites irritatingly abuse this and just add the feature anyway. It just tells yiou they are dodgy rather than trustworthy. Any up-to-date advice as on July 2025? Any trusted new extensions/addons for this as with auto-cookie form-fillers perhaps?

Hello, FF support forum,

I think I have seen a Container retain my login to a site when I open it again after closing it. Is there a way to configure Containers so that they are mini versions of the dump-cookies-temp-data when I close Firefox entirely? I would so love that functionality.

Regards, G.W.

I regularly use a website which intercepts command-option-up and command-option-down for its own navigation. This is a central part of my workflow with this website, and without it it becomes completely unusable.

After updating to Firefox 140.0.4, these shortcuts are now used by the browser to switch tabs. I have not found any way to configure this. Am I missing some obscure way to do this or is this just impossible?

I imagine this change was made to support vertical tabs, but I'm not using those, so the command-option-left and command-option-right shortcuts make more sense for my horizontal setup. (I don't use those shortcuts either, though- I use ctrl-tab and ctrl-shift-tab!)
