Example video I have issues with: (https://www.youtube.com/watch?v=udXuzXhb9WY)

I can't watch youtube videos smoothly using the vp09 codec at 4k/1440p [Codec: vp09.00.51.08.01.01.01.01.00 (313) / opus (251)]. Constant buffering, lag, pausing of the video or just not playing at all keeps occurring with the video I put above for example, and other videos using the same codec.

My internet connection is very quick in fact, with getting ~90mbps upload/download. My computer specs are good, having an i7 12700kf and an rtx 3060 with 64gb of ram. All my drivers are on the latest version. The video I linked above plays for about 10 sec before not loading more of the video and just infinitely loading (The main issue that is causing this to happen is that when I open stats for nerds, the buffer health isn't being updated).

I tried various solutions online that I found on forums, such as forcing av1 encoding, which fixes the issue, however on that specific video I linked, keeps the quality at 1080p, which probably is a issue on youtubes part and the file format of the video. I tried many other fixes.

On microsoft edge, the video plays fine with no playback stutters or anything. I don't have any 3rd party extensions installed that may affect the video playback. I did a lot of things to eliminate as many variables as possible, but the issue persists. I did a full reinstall of the browser, reseting cookies and temp data and also trying the nightly version of firefox, but non of those fixes worked. Basically everything I thought of I did.

Like I mentioned before, this issue is NOT only for the youtube video I linked, but its for all videos using just the vp09 codec for the 4k/1080p quality. The only fix I did find for that video is actually while writing this, I left the tab open for the youtube video for a while then played it and it played smoothly with no interruptions and the buffer health was constantly being updated, but after refreshing the page, it was the same.

From what I can remember this issue hasn't been happening for the lifespan of my pc (less than 6 months), and I cannot remember when the issue started happening. It seems to be pretty recent (maybe 2-3 months if I were to guess). At first I started tolerating it and thought it was a small bug since it only happened on videos I played at 4k using the vp09 encoder, but now its really frustrating and makes it possible to watch most 4K content. Some videos I notice when it starts buffering, it resorts to an alternate av1 codec for 4k video, but its only for certain videos. Unfortunately I cannot back track and see what started this issue.

Here is some additional info:

   Windows 11
   NVIDIA Game ready driver version (555.85)
   No abnormal resource usage (Gpu, Cpu ram etc.)

There's not really much skirting around it. Yesterday, I came across this sudden error with my Firefox browser on PC (see annexed image), which basically rendered me unable to open it for some reason. It did get fixed that same day somehow, though for a short while, as I was faced with the same error message again today and once again haven't been able to open my browser, much to my frustration.

I tried searching about it on the internet, but didn't find anything of help – most videos about it refer to a mistake on the Windows OS with the same code (0xc000185); asking around to people I knew didn't do much, either.

Today I tried a bunch of stuff to see if it resolved my problem in any way, such as: 1. Restarting my laptop (didn't work); 2. Installing both suggested and optional updates available to my Windows version (put me at ease a little, but still didn't work); 3. Searching for malware (antivirus didn't find anything, so I'm thankful this one didn't work); 4. Verifying system files with 'sfc /scannow' (all was good, so it didn't work);

I was also going to try doing a 'chkdsk /f /r', but I didn't have time to, as I had to leave for something. There are also other things such as creating another profile, which I'm considering; updating Firefox, which I can't do because I can't open the browser to check if there are any updates; and reinstalling Firefox, which I'm slightly afraid to do and will leave as a last resort because I don't want to risk accidentally doing it wrong and losing all my history, bookmarks, etc.

Any help would be incredibly welcomed. Thanks in advance.

P.S.: The text on the error message reads (translated from PT-BR): "The app couldn't be started correctly (0xc0000185). Press OK to close the app." Sorry if the photo isn't very good.

Hi all,

I feel like this is a problem that must have been experienced and solved a thousand times... however I've tried all the suggested fixes I can find and the problem still persists.

When I load Firefox the pages take ages to load. It doesn't matter what the page is, it takes ages, except that about: pages load fine, no problem. When I say pages take ages to load, I mean that everything about the page takes ages, not only the next, not on the images and other content etc, everything. This only started happening today and I only created a new profile a month or so ago. I don't have many tabs open (maybe 20) of which 9 are pinned. I do have lots of extensions installed.

I've tried troubleshooting/safe mode, that makes no difference.

Private browsing and loading another profile are fine, they don't have this problem.

I've cleared all cache and data, cookies, etc, including startup cache.

I've deleted the content-prefs file, and removed places files.

I've tried disabling and enabling hardware acceleration.

I've tried disabling TRR.

Probably some other things too, but so far nothing has worked.

Suggestions please! :)

Good afternoon,

I am not sure if the topic is the right one I choose.

My question/complaint: recently websites, although mostly websites from my bookmarks, seem not available or existing. Mostly after a few minutes and a new trial, the website comes back as if nothing was wrong. Could it be the last update from Firefox? I never had these "problems" (a big word for minor inconveniences) before and I use Firefox at least during the last 15 years.

Thank you in advance for your answer.

Best regards, Rien de Vos

Hello, Whenever I try to open something on Firefox, for example, the Library, I get the message "Mozilla Firefox (Not Responding) and it hangs with no immediate responsive action. I click on any Firefox button or tab and I get the same message and I get the blue little circle and I sit and wait about 30 seconds or more. The page or tab eventually works but it hangs for 30 seconds or more. It is frustrating. Please help.

Thanks, Tricia

Looking for a fix on a right-click issue that I keep having...

When using Linux Mint (Cinnamon), the right-click context menu occasionally becomes misaligned with the cursor position. Attached image shows a right click on the text box in the right browser window triggering a popup in the left browser window.

This most frequently happens when:

• Multiple windows are open AND
• The window being right-clicked on is "snapped" into place (by dragging to the side of the screen)

Error seems to occur most frequently on windows snapped to the right-hand-side of the screen.

Context menu placement is offset by an arbitrary amount determined at time of window-snapping. E.g., moving the cursor down 1 inch in the example image below will move the menu down 1 inch as well. Un-snapping the window, and re-snapping can adjust menu-cursor-offset distance.

When I open a locally downloaded pdf in firefox, the background is displayed as what was previously displayed on that portion of the screen, and scrolling simply overlays moved text over what was previously displayed. Does not appear in screenshots. One of the images shows what the pdf looks like prior to scrolling, and one after.

If you experience horizontal lines appearing when scrolling after installing firefox possible fix is finding layers.acceleration.force-enabled and set to true after going to about:config in your address bar search for this and set it to true. My real question I ask myself is, why isn't this enabled by default when installing firefox? I swear I remember doing this last Win 11 install as well. My third time installing windows unfortunately, just had a nvme ssd drive fail on me. 😭😢 Ofc, it had to be my Gen 4, C: drive with my old User account on there as well. :// Lesson learned, always backup important data frequently as desired. :( Oh well, just lost all my saved games and few songs, no big deal I guess.

Firefox Desktop issue,

McAfee malware has entered the Firefox browser a couple of days ago claiming viruses have been detected & requires me to click on their popup to remove it. Additional warning follow and reoccur every couple of minutes. I don’t have McAfee Anti-virus software on my computer & have not installed any new software for some time. The anti-software I have works fine (Spybot & Microsoft Security Essentials) and detects no problems. The first application I initiate upon boot-up each morning is Firefox and that’s when the problem begins. It is somehow related to Firefox. I cannot find any processes in play.

I’m using Windows 7 Pro

Sincerely, [removed email from support forum]

I tried all six free malware scanning programs suggested but nothing found

I am having problems playing a particularly demanding video from YouTube (https://youtu.be/-W_nFlIAWFM) which runs at 4K/30 fps. It is a video taken from a drone flying over the Matterhorn in Europe. Here is my configuration: 1. I have a 200Mb connection to the internet and bandwidth testing confirms that it runs at a consistent 195 - 202 Mb. 2. I am using Firefox 126.0 on a dual boot machine running Ubuntu 22.04 LTS and Windows 10 (both OSes show similar stuttering and pausing). 3. My hardware is a Gigabyte Aorus Z690i motherboard with 32 GB of RAM and an Intel i5-12600K processor and an NVidia GeFroce RTX 2060 Super graphics card. I have tried disabling "Use hardware acceleration" in Firefox and also disabling all add-ons and rebooting. This hasn't resolved the problem. When I watch the same video in Google Chrome, it seems to display a much slower frame rate than 30fps but doesn't stutter. I have concluded that this video must be a super demanding one to render. There are many picture elements changing constantly. But is there a way to watch this at 4K/30fps with it playing smoothly and at the correct frame rate?

Firefox was running in full screen. Without me doing anything it reduced it's size to about 1/4 screen. Everything I attempted to correct this has not worked . Any thoughts or suggestions on how to correct this is appreciated.

Hi, there - Over the last few months, I've noticed some things that make it impossible to get to websites. I keep getting "Secure Connection Failed," for example, with getting to Chewy.com. I just tried to sign into the ssa.gov website, but it comes back repeatedly as "403 forbidden." And another big one is trying to get to outlook.com. It never fully loads. I cannot get my email. I've been having to use Edge more and more, and I don't like that for privacy issues. Also, sometimes I cannot finish buying things on some websites without changing over to private browsing. Thanks.

I have used a free Hit Counter for many years that I got from https://www.freecounterstat.com/

I have 3 such counters and have stopped working in the latest version of Firefox on my desktop. They work with Firefox on my iPad and Android phone. They also work fine if I use the Edge Browser but I prefer using Firefox as I have for many years.

The embedded code is pretty simple, here it is for one of my counters... <a href="https://www.freecounterstat.com" title="visitor counter"></a> Can you help? Thanks, Bill T

Hello, so when I watch youtube on FF my cpu usage goes up alot and the fans go nuts. I have a very capable i5, rtx3070 machine and this issue started just a couple of days ago. I have not done any changes or updates which could trigger this problem. The problem starts mainly when I Watch in full screen mode or have multiple non-fullscreen vids active. All other apps show no signs of problem. I can watch the exact same video in Edge, no fans/high cpu, VLC works fine, Chrome is OK, it's only in FF that the problem occurs.

I have tried the following: 1.Reinstalling FF 2. Activating HW acceleration in FF and forcing it in Windows11 3. Theatre mode is off and all other YT settings are off. 4. Updated Nvidia and windows 5. FF is the latest version. 6. Disabled all my addons/plugins

No clue what can cause this..

Hi I had some tabs open in private browsing which have frozen. Each tab has history but won't let me go back or forward. I have tried closing the tabs and pressing undo as this sometimes works but it didn't help. I really don't want to lose the tab history as it is in private browsing so won't be saved in history. Does anyone know a way to restore the tabs?

Hi Support Team, Hope you are doing well. Do you have any issues with the service as I see from https://downdetector.pl/status/duckduckgo/ 144 was reported?

If you can just email me about reason if there was any malicious activities I happy to help.

Thanks RO
