Firefox Version: 124.0.2 (64 bit) Windows Version: Windows 10 LTSC 2019 (Version 1809)

When I right click the taskbar and press close Firefox, here comes the interface just as the screenshot uploaded. The blue close button doesn't response no matter how I click it and the Firefox's taskbar is flashing yellow. This bug only occurs on the first window of Firefox and only when user right click the taskbar.

It has been a long time for me wishing that some updates would be released soon to fix this issue, while noting happens. Or this bug is only for me?

Nvidia RTX Super Resolution seems to only work very rarely or not at all compared to the Chrome version. In some instances it will upscale the Full-Screen Video. It will not interact with windowed videos at all. But it will never upscale a windowed version that exceeds the playback resolution.

Steps to reproduce for windowed videos:

  1. Open any youtube video
  2. Set the resolution to 480p or lower (as I am using a QHD 2560 x 1440p monitor)
  3. Playback the video and monitor Nvidia Control Panel to see if Super Resolution has activated.

Observation for windowed videos: Feature works in Chrome. Feature does not work in Firefox

Full-Screen and Super Resolution: I have no idea what is going on here, on very rare occasions it does work, for the most part it does not work at all. If I had to give a rough idea of when it works, I would say that it is more likely to work when Firefox has been freshly launched.

I could neither see an active change in the Control Panel, or notice anything in the video quality. Both a quality change and feedback in the Control Panel occur when using the feature in Chrome. I have tested on identical links, with identical quality settings.

I tried:

  • setting the Super Resolution Quality manually, instead of manually
  • an incognito tab

When saving/opening file dialog is on screen the whole program freezes and take forever to unfreeze to the point I have to force quite the program. The problem seems to be only in Firefox.

Safe mode - same problem, Have done a complete refresh - same problem. Clean uninstall and reinstall - same problem.

Have moved to Chrome - similar problems.

This has been happening to me with recent updates of Firefox, and I am very close to dumping a browser that I have used for years because of it. I go to load pages and it just sits there and spins and spins. In the time I take to open another browser like Chrome and copy and paste the exact same links into Chrome, where the download of the web page is practically instant. I go back to Firefox and it is still spinning and it is just ridiculous. I have no clue what would be causing this. After it finally loads a page, it seems fine on subsequent loads of pages.

I would like a solution to this to ensure this doesn't haven't happen again. Thanks.

I see my original question is now archived at https://support.mozilla.org/en-US/questions/1380948#question-reply I never closed it because I didn't know if my last process could really fix the issue. It didn't, not always. Over the years, there have been times when the issue would still pop up, but not as often as before (2022 and earlier).

I have a feeling that during an issue, FF is having difficulty setting up shop after starting up. Consequently, it is spending more time before it could become prepared to connect to the Net. I've come up with another "solution," which is deleting (or moving out) xulstore.json in the profile folder after exiting or before starting FF. You can create a batch command or script to execute the process.

So far, FF is connecting immediately after startup.

Download files (pdf, xml) don't open in application (acrobat, firefox) since 125.0.1 Firefox version from IBM Power server with Ubuntu :

The message is "Fichier non téléchargé - Risque de sécurité potentiel" that is "No downloaded file, potential security risk" :

When we download a pdf file from the server, the "choice box" allow to . open in the browser or . open in Acrobat or . download on my PC. The opening fails with this message. This is the problem. The download on my PC works and when I open the file from my PC it works also.

We need this function of opening a pdf or xml directly from a server IBM Power with Ubuntu. It was OK for several years until 125.0.1 Firefox version. We had no change on the IBM server.

Can you repair this problem quickly. My PC uses Windows 10

All Add-ons are disabled and Firefox still can not play SOME of the videos on twitter. All I can see is a spinning circle on the center of the frame and the video will never be played. I tried other browsers and they all works well. It seems this issue has nothing to do with my network connection.

I searched this forum and find out some thread reporting issues of not playing All videos on youtube/twitter. Replies to these thread provided some solutions ,like update ffmpeg , set media related options in about:config. I tried them all and neither of them work for me.

Picture-in-picture since recent YouTube update keeps closing. Is there way i could configure in about:config to never close and always stay open even if page refreshes and have it move the video play back always to the Picture-in-picture window ? If not could this be made a feature in a future update ?

YouTube especially been annoying to Firefox users, cos it keeps refreshing the whole page breaking stuff every time it plays the video, as well have issues with looping videos even tho they are already fully buffered, making entire YouTube experience as frustrating as possible as encouragement to switch to chrome, which i refuse for obvious reasons.

Anything i can do on my end ? If tested if this happens in incognito mode as well with all extensions disabled in private windows, no change of behavior.

Btw this happens on the new YouTube interface with no way to get back to the old interface, cos it keeps the annoying features of the old interface even if you try to re position stuff using hacky ways like extensions that do so, which of course break stuff even further. I just want Picture-in-picture to remain open, and to play current video in picture-in-picture that is playing automatically.

Btw the Picture-in-picture experience with chrome or chrome based browsers is absolutely horrible, giving me even more reasons to stay on Firefox besides privacy related issues and other issues.

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?
