Firefox Community Forum

I've freshly reinstalled Windows 11 and after trying to access and watch a movie on any of these sites I get an error (see the pictures).

Browser version: 137.0.1 (64 bit) Widevine version: 4.10.2891.0

Already tried to disable/enable DRM. Already reinstalled firefox. Already manually installed widevine. No clue what could be causing this issue.

Even in the notification setting found under privacy and security there are no sites listed, however, I am continuing to get banner notifications even after uninstalling the browser.

I was trying to go to ssa.gov, today, and hit the button to login. When I did that, I got a 400 page saying: Bad Request

Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

I have done this before, and it worked. To test if it was a problem with the web page or the browser, I did it from another browser (Brave), and it loaded fine. Is Firefox sending a bad request? Is this something you can fix.

I am using Mozilla Firefox for Linux Mint 137.0.1 (64 bit).

I am having a problem saving my work through a portal I am using for work on Firefox.

While trying to fix this problem, I went to Firefox Settings and noticed the following hyperlinked text: "Your browser is being managed by your organization." This is my personal computer, so I don't know what organization it may be referring to.

Clicking on it brings me to a new tab called "Enterprise Policies". In that tab is a list called "Active" with two columns: Policy Name and Policy Value. The only item listed is "DisableAppUpdate" with the value "true". This may be the cause of my original problem, but in any case, I want to be able to run updates!

I am using Firefox 137.0.1 (64-bit) on a Pop_OS system.

How do I turn off "DisableAppUpdate" and run updates?

I am receiving pop-ups from what appears to be Mozilla Firefox saying: System is infected! Viruses detected, Turn on protection and delete viruses. The virus identified is ZEUS.2020 Trojan. Click here to scan and clean via: d3av3500fes73a78mk0.mosgdefender.com This link doesn't work. So, how can I get this issue resolved? Any help would be appreciated. These pop up happen frequently one after the other. I appreciate any help solving this issue. Thank you, Tricia Hawkins

When I first open Firefox from the icon in my taskbar the opening window says the following:

'Unable to connect Firefox can’t establish a connection to the server at 0.0.0.4. The site could be temporarily unavailable or too busy. Try again in a few moments. If you are unable to load any pages, check your computer’s network connection. If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.'

However this is only the first window, after that I can open a new tab in the same window without any problems.

I have uninstalled and reinstalled Firefox without avail. Can anyone help please?

1. i believe ur updating crashes my window 11 desk top

 2. While i'm watching youtube, doing word processing (.txt) or when i set the PC to 'Sleep' mode,
     my screen either freezes w the display or turns black.  In both cases, my mouse and keyboard
     won't work.  Thus, i have to re-boot to fix.  Even Control-Alternate-Delete won't work to get out

 3.  Request not to keep on showing your pop-up window at top RH corner saying:

      Update Available

      Download the latest ...

     <Download> <Dismiss>

    Hey, either one of those two buttons won't stop blocking my top RH corner of the screen.  It's rediculous.
    Even after i hit <Download>, the same pop-up shows up again n again.  Same w <Dismiss>.

    Just remind me once per week.  And don't crash my PC!!!

4. There is no 'Community' info on this annoying update pop-up problem. Just stop it!

Pls investiate n reply via my email.

Thx

Hi,

I've search on all forums, dived deep into my firefox settings, even disabled Containers... No luck : I cannot see tab groups :(

Could you help ?

I have removed Firefox and installed fresh the latest version 137.0.1 to address the issue of not being able to start a new tab or a new window. I am writing this from the initial window that opens when Firefox is launched. If I try to open a new tab it will hang with the blue circle displaying. If I click anywhere on the window if will grey out the background and display the error message :

Firefox is not responding

if you close the program, you might lose information

-> Close the program -> Wait for the program to respond

Tried waiting and it never comes back. Only option is to close the program. After that there is a message that is reporting the issue to Microsoft.

I have accounts that will not work because they cannot access my location, My computer says all access is allowed, so is there something in Firefox that blocks my location?

When I creat a new bookmarks they are not automatically put in alphabetical order but instead are placed in the ned. Why not put them in order when they are made? Anyway, I tried to use the option that allows me to sort bookmarks alphabetically but nothing happens. This used to work but not now. I am using 137.0.1 (aarch64)

I have attached an image to show what I mean.

'Running ver 137 and now cannot print to my system default printer. Tried the Troubleshoot fix and same result - defaults to PDF. Is there any entry in about:config to ensure system printer is selected. I have checked all system settings and brother printer is the default.

I left my computer for a while, and when I returned and took it off screensaver I started going through my emails when I noticed that the bookmarks on the toolbar are missing. The toolbar is present, and I toggled between only show on new tab, never show and always show a few times, but they're still missing. I even tried bookmarking two webpages, but they were not added to the toolbar. As stated, I have the bookmark toolbar to always show. Firefox just updated yesterday, 4/8/25 to 130.1.0, and I'm pretty sure that they were there this morning, but I can't be totally sure. I noticed my computer had updates available, so knowing updating it would not have any effect on Firefox, I restarted the computer while updating so I could also restart Firefox with a bit of a delay. I had also restarted it twice before without any luck. The only thing I did besides updating Firefox was enabled the sidebar, which I then turned off and still did not have any bookmarks in the toolbar. Any assistance would be greatly appreciated, but I may not be able to view and any responses or make the stated changes until Friday.

Ok for some reason any of my browsers tabs are crashing I just do whatever it is whether i search or watch movie and after some time 'Gah! your tab crashed' and it's pretty annoying, my discord happens to restart it self and I've exhausted literally anything from re-installing, deleting caches folders absolutely anything.
