I recently installed new pc with fresh Firefox Developer Edition. Then I transfered the profile folder from old pc to the new pc. All bookmarks, addons, etc is there. Just the XULRunner popup appears only on the new pc. I uninstalled firefox on the new pc again and reinstalled it with profile cleaning. After profile cleaning firefox got faster and addons got removed. But the XULRunner popup keeps appearing. When I go to taskscheduler and trigger the "Firefox Developer Edition Background Update CA9422711AE1A81C" again, the XULRunner popup appears. Removing this taskscheduler and Firefox keeps readding it and the XULRunner popup are back. Any idea how I can get rid of the XULRunner popup?

A few days ago I was downloading a ZIP file and was warned that "This file contains a virus or malware". Fine, thank you for telling me but now how do I seeing the same warning every time I start Firefox? The file in question does not exist on my computer so far as I can tell and I did a thorough search through 3.5tB of storage on the machine to make sure. How do I stop this warning?

I cannot watch a video on youtube when it is in the process of being live streamed. I remember a time when I was able to, years ago, but I can't any longer. I'm not sure what has changed. I found an article that says to install the optional update called "Windows Media Pack" in apps and features, but no app with that name exists. It was only a year old solution, so I'm unsure of what changed so significantly. I just installed another optional windows update, and also updated the browser, but still doesn't work.

Hello,

Whenever I use Firefox, I end up seeing popups (necessary for school) and would like to show them as tabs so I can merge them into other windows. I have tried the solutions given in: https://support.mozilla.org/en-US/questions/1080255 and nothing seemed to work. Is there another way to make sure that popup windows cannot hide the toolbar and show tabs?

I first realized an issue with downloading PDFs through the Firefox viewer - I cannot. The download button does nothing, there is no prompt, no popup, and no file downloaded. I have also tried to print to pdf, that also seems to fail.

Today I realized I also cannot attach any files to an email through Gmail in Firefox, which is now leading me to believe that the software is unable to interface with my files at all.

Things I've tried include: - Turning off popup blocker - Refreshing Firefox in the ->Help->More Troubleshooting Information Menu - Starting Firefox in safe mode - Reinstalling through snap

The only way I can currently download files is through wget, and the only way I can send attachments is by installing Google Chrome, which is kind of a last resort for me.

I am running Ubuntu 22.04, this is on Firefox 106.0, though it didn't work last update either.

Thanks for any help


Edit: I have been googling for answers but after posting this question a similar thread popped up, the solution is to install the following packages:

YouTube Video GPU Decoding only works in Troubleshooting Mode

I recently upgraded graphics cards from an Nvidia GTX 1080 to an AMD 6900XT. Since then I noticed video stuttering on YouTube while playing 4k videos, especially noticeable at 4k/60FPS (example video ). Prior to the upgrade, I was not experiencing issues.

I monitored task manager as the video was playing to see CPU usage, which was sitting at 25% (4 core 8 thread CPU). GPU usage was fluctuating from 1-3%.

I tried resetting all the changed configuration options in about:config, removing all add-ons, "Refreshing" Firefox, and ultimately uninstalling and reinstalling. Nothing has worked so far except for "Troubleshooting mode" in about:support. In that mode, I experience no stuttering and GPU usage rises to 25-35% with the video playing, even before I reinstalled.

This most likely isn't a networking issue as the "Stats for nerds" option on the YouTube video shows I have 10-20s of buffer while the video is still stuttering.

I would like to find out what's different about Troubleshooting Mode that is not giving me the same problem while in "Normal Mode". Any advice?

Hi,

I've been encountering a strange issue where colors (especially whites) in the video player are super washed out. This only happens when HDR is turned on in windows, and only happens in my Firefox Developer Edition installation (normal firefox works fine). It also doesn't show up in any windows screenshots - the colors revert to normal when I'm in the screenshot GUI. I've attached photos below of a youtube video, the left is firefox DE and right is normal firefox, both in and out of the screenshot GUI so you can see the difference.

I'm on Windows 11, and I'm not sure what caused the issue. I've tried both refreshing and reinstalling firefox DE to no avail. Pretty stumped on this one, and would appreciate any help!

Hello.

It seems I get a problem or two almost always with a new update lately. I have been using an userChrome.css to reduce the width of sidebar but the latest version 107.0 now ignores it and have a wide width even at the narrowest. Mine currently is set as, "#sidebar {min-width:30px !important; max-width:none !important;}" This no longer works. Your support much appreciated.

Regards,

Is there any way I can completely disable horizontal scrolling? I'm using a laptop with a trackpoint (lenovo x230, Windows 10) and it's not terribly accurate, which means scrolling whilst a youtube video is going often makes it track backwards or forwards, and another website I use uses a horizontal click to send me to the next page, which sucks. I would prefer to just be able to disable it entirely. Thanks!

I swear to god I used to have it disabled, just need to work out how again.

I had set up a userContent.css file in the past to pull up and fetch an image on my computer to display as a background on the homepage. It worked and did it's job until recently, when I had recently relocated a lot of my files around on my computer. I have redirected everything to where I want it to look, including the userContent.css file to the new location for the image I want as the background. Firefox loads the .css file correctly, and recognizes the file existing, but it won't load the image itself for some odd reason. It states it "may not load or link the file" because of a security error, and thus, can't load the image. I never had to deal with this before. How can I get Firefox to be able to load my image like I want it to? I have screenshots that I can provide, but this site doesn't want to upload them at the moment.

In the new version of the Developer Edition the options "close tabs to the right" and "close other tabs" are in a sub-menu named "Close Multiple Tabs" inside the context menu. Is there's a way to change this so that they will appear directly in the main context menu? I use "close tabs to the right" often and I find this very annoying.

On my laptop, I run FDE as my daily driver, with the release version to handle my webmail. I also use portable firefox (from portableapps.com) as a browser to use while at work, from a thumb drive. While using that portable verison, I usually just go to google image search, and a work site that would definitely be secure.

My question: I don't like to update the installation on my thumb drive very often, and occasionally work computers are very slow anyways. So if I were to update it no more often than once a month, which version of firefox would be most secure: Release, Beta, or Nightly?

If doing this is just dumb, then which version gets updated less often--it would be Release, correct?

Google search pages not showing text after Mac OS 12.6 Monterey upgrade

Since upgrading to Monterey, Google search pages show almost no text in Firefox. Google searches in Safari and Google Chrome are completely fine. Only Firefox is showing the problem. The blank text includes dropdown menus too - all options inside them are blank. Currently on Firefox v107.0, but the same problem happens with older versions.

If I go into Troubleshoot mode, the Google searches are working fine. I have refreshed Firefox, Cleared the startup cache. But the problem persists. I uninstalled Firefox from the machine, restarted the computer. Did a fresh download and install, haven't signed in so there are no addons/extensions to cause problems.

This is happening on both an Intel Mac and an M1 Mac running Mac OS 12.6 Monterey.

I attach one screenshot showing the same page with and without troubleshoot mode on. The second screenshot shows another page of results including what looks like weirdly encoded characters.

I've followed all the suggestions in the support page but nothing has helped. I'd really appreciate any advice on further troubleshooting. Thanks in advance for any help.
