Since yesterday, some of my tab groups don't fully collapse when the group tab is clicked. Instead, one tab in the group remains fully expanded, followed by a number indicating how many other tabs are in the group. A screen shot is attached.

Since I enabled tab groups some weeks ago, tab groups have behaved as expected. When the group header is clicked, the tabs in the group spread out to be visible and clickable. When the header is clicked again, all tabs in the group collapse entirely behind the header tab.

Most of my tab groups are still behaving this way. But new groups are now displaying one full tab plus the number, no matter how many other tabs or tab groups are already occupying the window.

Since the behavior is inconsistent, it doesn't seem to be a setting. Is there any fix?

Whenever I play something in the browser while connected to my TV by HDMI, the sound still comes out of the laptop speakers. This happened suddenly, without any discernible reason, and I can't seem to fix it. Everything else works, only content played from Firefox remains in the laptop speakers. I've checked my audio mixer, nothing seems amiss, I've updated Firefox and refreshed the application, still nothing. Hell, I've even tried different cables and HDMI ports, but nothing works. What could be the issue? Why did my audio suddenly stop working, and what can I do about it?

Using Firefox--When I try to access the daily set of images that comes in an email representing memories for this day which is pulled from my Onedrive Photos, all I get is a dark blank screen with a subtle pulsing wave as if it is searching.

I get the same thing when I go directly to my OneDrive Photos and try to pull up the daily photos there.

However, changing browsers and using Google Chrome--I can view the images in the memory email as well as those on my OneDrive directly

What does Chrome do that Firefox is not?

I recently had another browser related issue on a different problem trying to register online with Directv which would not complete with Firefox but when I used Google Chrome instead of Firefox, it worked.

This made me wonder if the above OneDrive image problem might be browser issue. Sure enough, it was.

I really prefer Firefox and I do not want to have to go to Chrome.

Hello.

My Firefox browser is missing the close button from the top bar. Minimize and Maximize buttons are present.

This is happening on Fedora 42 With Gnome.

I believe I don´t have any custom theme or user css or extension that could cause this.

Also because, it seems to be hapenning not only in Firefox itself, but also in Firefox based browsers, like Tor Browser.

Anyone has any idea what is hapenning?

Thank you.

Issue: A regression in Firefox version 142.0 (64-bit) breaks the display of the CAPTCHA widget on the login page for https://my8k.me/login

Evidence: The two attached images provide a clear comparison:

   Image 1 (Firefox 142.0): The CAPTCHA area is completely missing or fails to load, showing only a broken element or empty space.

   Image 2 (Other Browsers / Older Firefox): The CAPTCHA renders correctly and is fully functional, confirming the problem is isolated to the latest Firefox update.

Conclusion: This indicates a specific compatibility bug introduced in Firefox 142.0, rather than a general website or user configuration error.

При заходе на сайте ya.ru и если на нём имеется строка с видео или поиск с алисой, то начинаются сильные фризы. Это ошибка именно в firefox 142, проверенно.

On a new tab page, I have unselected "recommended stories" and added four rows of shortcuts. Almost invariably, when I open a new tab, Firefox has added a couple of new shortcuts, bumping two of mine off the page. The shortcuts I've selected are the ones I want. I would like Firefox to stop making suggestions. Does anyone know if that's possible, and, if so, how do you do it?

Hmm. We’re having trouble finding that site.

We can’t connect to the server at data.digital.costco.com.

I have switched from chrome to firefox on my windows 11 laptop. I want to do the same on my pc but after signing into the Mozilla account, the bookmarks do not come in. History, and other things seem to work fine. I tried manually synchronizing in the settings over and over again but nothing works.

I have no idea what to do other than going back to chrome where things just worked and I didn't have to spend hours looking at forums for solutions that do not work...

here's a screenshot from the last txt file

Current Behavior When Firefox is set to offline mode (File → Work Offline), the Developer Tools Network tab does not display request body of requests that web applications attempt to make. This creates a significant gap in debugging capabilities, as developers cannot inspect request payloads details that would normally be visible.

Requested Enhancement Enable the Network tab to capture and display attempted network requests payload even when offline mode is enabled

Windows 11. I have my taskbar behaviour set to ‘Automatically hide the Taskbar’ So usually the Taskbar is not displayed, but when I move my cursor to the bottom of the screen it reappears. With Firefox I cannot make the Taskbar reappear.

Every couple of minutes Firefox just freezes. YouTube buffers, all open tabs just stop working. I can open new tabs but i cannot search up anything or go into any websites. Is there any fix for this?

Have been having an issue for the past month or two where if left in the background firefox will slowly start to eat up my available ram. I was using it like this perfectly fine for years previous to now.

I dont have this issue when I'm actively using it, only when I tab away from it and specifically its not on screen. Once I tab back to firefox the ram usage immediately dips back down to normal. I have tried many things to try and solve this like doing a clean install of firefox, getting rid of extensions, clearing my browser cache, closing all other apps to verify it was just firefox, clearing my history, turning on hardware acceleration. Nothing seems to help, im really at a loss and I don't understand what changed besides it being updated in the past couple of months.

My computer is fairly heavy duty and I have 16gb of ddr4 ram that again was working perfectly fine to run firefox before these past couple of months. As a result of this issue however if left in the background for too long on accident firefox uses up all my idle ram and starts causing other programs to not be able to run and has even crashed my computer previously when trying to run a program like clip studio paint.

I have noticed that while running the firefox task manager there is definitely some difference in memory usage when i tab back in after letting it be in the background so I have attached screenshots of the regular usage while tabbed in and the captured usage when i tab back in.

Any possible solution is welcome because I really enjoy using firefox and i dont want to have to switch browsers unless absolutely necessary.

For a while now firefox has been unable to enter fullscreen when pressing F11. Instead all it does is move the "Scroll forwards", "Open a new tab", and "List all tabs" button over slightly (The buttons on the top right, next to the minimize and close buttons).

I don't know what's going on with firefox.

Firefox Version 142.0.1 (64-bit)
