Hi All,

I would like to remove the first item from the Tab Context Menu, which is "Add Tab to New Group", and simply have "Reload Tab" as the first menu item.

I was using this code, which worked until the latest update...

#context_openANewTab,
#context_moveTabToNewGroup,
#context_moveTabToGroup,
#context_ungroupTab + menuseparator {
   display: none !important;
}

However, now there is an extra separator line at the top of the menu (see attached images).

Is there a way to remove the first menu item without adding the separator line?

Thanks!

'I am running fiefox version 147.0.3 in MacOS version 26.2. Every second time I start the program firefox tries to take 15GB of memory. The process does not respond (as this is equivalent to more than the memory available plus the swap space). I have to kill the process and the second time the program has standar memory needs. How can I help developers?

Hi. Cannot seem to figure out how to remove 3 Mozilla Firefox notifications appearing vertically up the right side of my windows 11 LG gram laptop. They are covering up part of the mozilla dropdown window when I click on the 3 little lines in the upper right hand corner. Sorry, not very good at explaining this. I know I have to eliminate these spam notifications, just need step by step instructions... Please help me, Thanks [edited email from community support forum]

The website commonly used by Arizonans to make filings for court, will not work properly with Firefox, even after turning off Enhanced Tracking Protection. I had to use Chrome instead.

Hi,

Looking at my Firefox 147.0.1 settings for macOS 26.2 (Apple M1), I'm trying to adjust two settings:

-- I'd like to remove Languages -> English (GB) (its existence has odd side effects, like triggering United Airlines to offer fares in Pounds Sterling, and I'd prefer to just have English (US))

-- I'd like to disable Play Audio and Video for about:welcome (in regular and private windows)

I can see no way to accomplish this currently -- why?

Thanks.

I moved and my moving company had my computer soundly packed in a box. After 2 months I have hooked it up. Tried to open my Firefox and the message stated the file is corrupt. I've opened a new Firefox account. Can I get my old account back or can I get my old information into my new account?

I recently went to settings to make sure my default browser on my Windows 11 device was Foxfire. I think I also saw an option to move all tabs over from other browsers, but instead of adding these to my current ones on foxfire, I think it just replace all of the ones I had as they are not in my history any longer either. I went to the 3 lines, to settings, to general, made sure all was checked properly, but it did not help bring the others back!!! help

Hi, when I open up my file of http://www.preservingthesloughi.net/ it tells me that the item is not secure and does no allow the next step, detailing the information. Thanks Dominique de Caprona sloughi@gowebway.com

I've tried messing with hardware acceleration, resetting the zoom to 100, it seems when i get the zoom as low as possible it tries to fall back into place, i can't find any fix on this, i like this browser but i cant watch anything like this

I have the latest version of Firefox. I still keep getting the prompts to download the latest version. When I go to system info, it shows I have the latest version it is asking me to download. When I do a manual search for the latest version, it always says it failed to search for the latest download.

Mozilla made an update of my Firefox installation on my Win11 laptop. all my password disappeared as well as my history and bookmarks.

I have now a virgin installation and is starting from scratch.

Now I get this error message: "This profile was last used with a newer version of this application. Please create a new profile." I deleted met shortcut and I opened Firefox by using Windows search. Now I see 4 profiles! I think I do not need to create a new profile. Maybe delete 3 of them ? What to do ? And, how?

I had to actually sign up fort a Mozilla account,the multiple hoops I had to jump through were ridicules, in order to ask a question of Firefox. I do not want my address bar to be my search engine. How do I disable the search engine in my address bar? And now I have to wait for an answer!!!!!!!! I used to love and trust Firefox. Not anymore.

Environment - OS: Omarchy - File manager: Nautilus (running as --gapplication-service) - Desktop portals: xdg-desktop-portal + xdg-desktop-portal-hyprland (+ gtk fallback) Firefox: latest stable from Arch repositories

Observations Only one Firefox process is running (pgrep -a firefox). Only one Nautilus process is running, but it receives two open requests, resulting in two windows. The issue does not occur in Chromium/Chrome, which opens only one window. Running xdg-open <file> manually opens one Nautilus window.

Portal logs show GTK being chosen as last-resort fallback, but system-wide XDG configuration appears correct.

Question

Is this a known Wayland/portal bug in Firefox? Are there recommended debugging flags or patches to trace the duplicate launch request?

Hello everyone,

I’m experiencing ongoing problems with Firefox and hope to get some help or clarification here.

Main issue: I’m unable to sign in to my Outlook / Microsoft email account using Firefox. The login page does not load correctly, or the sign-in simply fails (Error 400). When I use another browser (for example Microsoft Edge), the login works without any issues.

System information:

Operating System: Windows 10 IoT Enterprise 2021 (LTSC, supported until 2032)

Firefox version: 147.0.3 (64-Bit)

Additional problems: Besides the Outlook login issue, Firefox has recently become more problematic during normal daily use:

Text selection with the mouse often does not work correctly

Clicking and dragging to highlight text is unreliable or stops working

Pages sometimes feel unresponsive, (ChatGPT)

Overall, the browser feels less stable than older Versions on Windows 10 22H2

These issues seem to be getting more frequent over time and occur on multiple websites, not just Outlook.

I switched my system to Windows 10 IoT Enterprise 2021 (LTSC, supported until 2032) in the hope of improved performance and stability.

What I have already tried:

Clearing cache and cookies

Disabling all add-ons/extensions

Testing in Private Browsing mode

Restarting Firefox

Unfortunately, none of these steps resolved the problems permanently.

My questions:

Is Firefox fully supported on Windows 10 IoT Enterprise 2021 / LTSC for the long term (until 2032)?

Are there known issues with Microsoft / Outlook sign-in specifically in Firefox?

Are there known stability issues (text selection, mouse interaction, page responsiveness) in recent Firefox versions?

What settings or troubleshooting steps are recommended to improve stability?

Thank you very much for your time and support.

Best regards, Marco Klecker
