I have read the thread for this similar problems, tried all the suggestions but I'm Still experiencing videos not staying full-screen. Is there any other solution to it? This has started since yesterday but everything was fine before then.

I'm developing a website and noticed while testing that firefox sends requests to "/sw.js" on my local webserver. When starting with a fresh profile folder, this does not happen (and also not with other browsers). So, I thought, this might be one of my extensions, but in Troubleshooting mode, the browser still sends these requests, everytime a site is refreshed. It does not affect performance or anything, I am just afraid that I was somehow hacked as I did not make many settings in firefox. Do you know, how I could further diagnose the problem?

I have Firefox 124.0.2 running on Windows 11. For some reason, I can't update Firefox. When I manually download the update file, it appears to run Ok, but the version doesn't change. If I go to settings and click on "Check for Updates" is comes back and says Failed to Check for Updates. How do I fix this?

Originally reported on April 11th /questions/1444593: I have Windows 11 and the Firefox 124.0.2 browser. I cannot update to the latest version of Firefox. I receive an error message "Failed to update". I've uninstalled and reinstalled the browser, ran the install utility selecting update, nothing seems to work. Please help

So I'll be typing like normal (I type 100 WPM), and all of a sudden, I'll type a sentence, but each individual letter starts taking about 3 seconds to show up on the screen. I have to sit and wait a super long time for everything I typed to finally show up. Other times, I move my mouse over something I should be able to click on, and have to wait a long time for the arrow to turn into a hand, letting me click on it. These periods of slowness will last a few minutes, then disappear.

What's really interesting is that when the slowness starts, I can type just fine up in the URL bar. I might type my entire message there, then copy paste it down to where ever I was wanting to post it. However, when I do that, if I have another tab open and that tab is playing music, the music will start to break up and lag as I type. Again, after a while, the slowness disappears and we're back to normal.

Can anyone tell me what's going on?

I'm running a UI deployment with a web-app and Firefox on an Ubuntu system.

I'm running Firefox with the flag "--kiosk" to place it into kiosk mode (booted from the command line upon system boot). This works fine, and boots up Firefox to the page I want (my web-app) in kiosk mode (full-screen, etc.)

However, I get very annoying popups that are not acceptable for deployments in front of customers. I have tried, but CANNOT suppress all of them, or, when I thought I did, they came back a month later.

Popups:

1. "Keep pesky trackers off your tail. Open my links with Firefox" 2. "Welcome back" 3. Others like this...

These are Firefox browser popups, not related to popups that other websites can put up, and block the entire screen with an overlay until they are dismissed. My deployments are only going to a single web-page that I control (which has no popups) and there is no keyboard on the deployed system, so people cannot navigate elsewhere.

Things I've tried:

1. Firefox is installed via snap, which provides "snapshotting" configuration for the Firefox snap. I loaded Firefox, cleared the annoying dialogs, and then took a snapshot (theorying that I set Firefox configuration when doing this, and I capture that in the snapshot) and re-installed it onto a new system. Still go popups 2. Looked into user.js preferences. I can install this file onto the system, so I looked through https://searchfox.org/mozilla-release/source/remote/shared/RecommendedPreferences.sys.mjs and this is how I initially got all the popups to disable themselves. I looked through that list and tested most of the recommended settings until the popups disappeared. However, after a month or so, I'm beginning to see the popups again.


Any suggestions from Mozilla or others that run into this issue?

  1. Sometimes I use the browser while the system is in dark mode.
  2. Then I switch system to light mode. FF recognizes it and switches to light mode accordingly.
  3. Then I use it in light mode for a little more.
  4. Then some time passes (maybe a few hours), I don't use FF during that time.
  5. Then, I tap on FF icon, the browser starts, but immediately switches back to dark mode, while the system is still in light mode.
  6. I have to close FF by swiping on it in task switcher, and then tap on the app again.
  7. FF now uses light/dark theme according to system.

Device: Motorola Edge 30 Neo with stock Android 14.

I am using Fennec: 124.1.0 (Build #1241020), 516df33ca9+ GV: 124.0.1-20240326023132 AS: 124.0

About a week ago I started getting these update error messages stating "Update available - Firefox couldn't update automatically. Download the new version". I've also tried clicking "Learn more" on the error message but it's a dead link. Going into the settings for updates I am set to auto update, but when I manually check for updates it says "Failed to check for updates".

The help article on this issue simply tells you to download and manually reinstall Firefox, but I'm having to do this nearly every day. I work in IT myself so I know a "bandaid" workaround when I see one. Is there a solution to this issue?

I have been using Firefox as my primary browser for a very long time. Now, every time I start Firefox, I get a message that the update failed, and that I should manually download the update file and run it. I do so, the update appears to work, and Firefox behaves, until I stop it and restart again. Then I get the same message. I looked online - it appears that others have had this problem, but no clear solution. I am not willing to use Edge, but am beginning to wonder if it is time to leave Firefox. I would appreciate a solution, preferably a reliable one. Thanks, Joe Purvis Email hidden for privacy reasons

Hi I am a longtime user of your browser. I have version 124.0.2(64 bit) installed on three devices. First thing I do on opening it is to click on "about", which normally updates the browser, before I do any browsing. In the last three weeks, however, it has not updated on any of the three devices, rather, it says "Failed to check for updates". I have tried the workarounds suggested at your Help center, and nothing has worked. What gives, may I ask? Thank you

After just turning on my computer running Windows 10, I opened Firefox. I open 1 web site and noticed my computer showed a (16) prefix when loading Firefox. I opened the Task Manager and it showed that there were 15 instances of "firefox" running in the background. All showed a UAC Virtulization of "Disabled". But they also showed using 638.8MB of memory. I do not know whether these are necessary files that must run in the background or if the number of files indicates that my system has been hacked and someone else is in my system from outside. Any suggestions as to validity of these files running or how I might confirm that they should be running. I have noticed the number of excessive background files before but the number is never consistent which makes me fear I may have been hacked.

I have Windows 11 and Firefox 124.0.2. Firefox keeps asking to reinstall. I think it is because I keep getting the message that it fails to check for updates. I don't know if I have installed the Microsoft Firefox or the direct Mozilla Firefox downloaded. Maybe that is the problem, but I am not tech savvy. I have used Firefox for many years and like it. I am also too old (83) to deal with these problems. Help!
