Firefox Support Forum

Having this issue with Youtube since a few days ago, on version 115.0.2 and 115.0.3, and only for videos encoded in AVC/H264. VP9 and AV1 encoded videos have no trouble buffering, only H264 is affected. Happens with or without adblocker, and on different OS. Cookies cleared, no dice.

Video would load the first 20-40 seconds, then does not buffer at all subsequently once it reaches the end of that portion. I have to skip a few seconds forward for it to load the next 20-40 secs, then it would get stuck again.

I can get around this issue by either lowering resolution to 480p (which looks terribly unwatchable), or turn VP9 streams back on (which does not work correctly on my setup, there's a driver bug that hasn't been fixed).

The sure way, and strange thing, is that AVC/H264 videos load and buffer with absolutely no issue when I'm logged out of my account. Also, works with no issue in Chromium, even while logged in.

Anyone facing this or similar issue recently too? Is it still ongoing for you?

I now have 115.0.3 and this problem still exists. It was reported right after 115.0.1 was released. When watching FreeVee on a Windows 10 desktop it stops a short while after an ad plays. It looks like it loses the ability to stream the main movie while streaming the ad. After the ad it plays about 20 seconds of the movie, probably what was in the buffer before the ad started, and then it freezes. I get the circle wait icon, like what typically happens when the Wifi goes down. After a while a message appears saying the Internet is not working. See attached image. Then I get the message (see other attached file) saying Video Unavailable. We're experiencing a problem playing this video. For assistance, please go to www.amazon.com/videohelp. Close Player.

Bug 1362767 is still a problem, even with fission enabled which is apparently the default now. This is a huge problem when viewing videos on youtube and other similar video server platforms. The memory usage by Firefox just accumulates and does not release even after several days. Eventually, Firefox needs to be restarted to release the mis-allocated memory back to the OS. (Win10, FF 115.03 64-bit, Intel I5, 32 GB RAM) A restart can cut total system memory as reported by Process Explorer in *half* or more (!!) depending on how many videos I have viewed since last browser restart using Process Explorer 'Kill Process Tree' function followed immediately by FF restart. It is no longer possible to use an older PC with 8 GB of memory with Firefox to view videos. It takes forever to load, then becomes so laggy that it is no longer functional and is even difficult to kill with Process Explorer because the Windows Explorer user interface gets forced to swap out. (This latter should never happen regardless of memory allocation and is the fault of Microsoft.) I am now using another PC with 32GB RAM and Firefox often pushes the physical memory allocation to well above 16 GB after viewing just a few hours of videos, and does not recover even after being idle and minimized overnight. I have 10 extensions installed. Four of these are video related: Enhancer for Youtube, Video Ads Blocker for Youtube, Video DownloadHelper, and Video Speed Controller. I have not found any improvement in memory allocation performance by selectively disabling extensions. Other people have been posting complaints about this problem for at least 6 years. It makes Firefox practically useless for systems of 16 GB or less. You need to fix this. It appears to be *your* problem; Don't try to deny it, please just make it better. I continue to use FF because of the very useful extensions and greater privacy features than what is available for Chrome.

I am running the latest version of Firefox (115.0.3 (64-bit)) with NO ad blockers. Whenever I try to watch videos on Paramount Plus, I get an Error 3005 message. I can watch videos on Paramount Plus on both Chrome and Edge where I DO have ad blockers running. What else can I do?

Hi all,

I’m trying to make aware people of the recent Google movements to close gate the internet to their services and I suggest to folks to move to Firefox.

One of my colleagues encounters a problem clearly visible on the image attached (it shows correctly on my mac).

It's not as bad on my mac, where I only have issues every now and then - I received an email this morning on my work email, and all the apostrophes were replaced with Registered symbol (R in a circle).

I noticed that not allowing websites to use their own fonts fixes the issue (unticking "Allow pages to choose their own fonts, instead of your selections above") but I would like to be able to view sites the way the developers intented rather than forcing my browsers default fonts.

Any ideas?

Many thanks

I am disabled and have been using Dragon for writing and reading for more than 20 years. With the new update I cannot install the Dragon extension into Firefox and the longer. This means I will be no longer able to use Firefox as my web browser. This means I will be going to another editor! This is a shame because I've used Firefox even before it was Firefox! (Netscape)

I have multiple windows open with multiple tabs on each. Most created before I had a Firefox login (if that makes any difference).

I am upgrading my os on my Mac and somehow either a) keep all the windows with all their tabs open (preferable) or b) easily create some record of what they all are so I could relaunch them if a) is impossible.

How can I do this?

I'm having an issue when saving bookmarks, I'll find a nice recipe, save it to my recipe folder, little blue star will show on the page showing its bookmarked but when I go to the folder, it's nowhere to be seen. I'm not sure what I'm doing wrong here, it use to work just fine before.

Earlier today (well, it's yesterday now) Firefox was updated to 116 and since then it won't download any images or other files from anywhere. I've set a default download directory and when I click "Save image as...", that image should appear in the preset directory but it doesn't. I have two extensions for downloading images and they work just fine, only the default function of firefox doesn't work. Here's a short video showing the problem:

I tried downgrading Firefox to 115.0.3 but that didn't fix the problem and I'm out of ideas how to fix it. I'm 100% sure it's a firefox problem bc I tried saving images with Opera and Chromium and there was not a single problem with that task in either of these browsers.

Hey every time i go to Facebook it keeps going super slow and continues to display the prompt bar where it says this page is slowing your browser down. to speed up your browser stop this page.... well its every single page. and this is happening to me on a couple of computers. I have cleared cache and cookies. I've turned off enhanced tracking. I've also tried opening in a private window and still the same thing.

I am desperatly trying to play a youtube video, the on hover preview plays, but the video wont. I turned hardware acceleration of and tested in safe mode. I am using Firefox version 115.0.3 from the AUR. pls help

I encountered a Problem since the last update. When watching a Video on Youtube, the Playback is flashing, especially on green and red colors. I did see some People mention a similar issue years ago, so I followed the same troubleshooting by disabling Hardware acceleration and all extension. The Issue keeps persisting I am browsing on a M1 Macbook Air - no other Browser on my System has that issue. Here is an example with Screengrab https://imgur.com/a/EFrzzAD

Hello team,

After the most recent update I have been having issues with the Youtube video playback. Upon loading a video it works fine, however once I click on the progress bar to skip to a certain point of the video, the video pauses, the progress bar tracker gets set to 0:00, the video starts buffering and I have to click 3-4 additional times on the specific time I want to skip forward to, in order for the video to even continue playing. I have restarted my PC, cleared cache and cookies, re-installed the browser and nothing works. Mind you, when trying to watch videos on either Edge or Chrome, there is no such issue and the progress bar works fine. I really do enjoy Mozilla, but if this keeps up I will have to change browsers it is bugging the hell out of me.

Looking forward to receiving any help.

Kind regards, Petar

Since the last upgrade Firefox regularly crashes. It becomes very slow then none of my tabs I may have open will load. Task manager tells me I have up to 27 firefox items running sometimes using huge amounts of CPU

Bitdefender keeps telling me it has blocked api.faviconkit.com. How can I permanently remove api.faviconkit.com?

Recently, my FireFox has been acting a bit strange when it comes to playing videos. I am using a site called Udemy to watch a video course I'm taking, however, the videos don't seem to play for either a long time, or until I tab into YouTube and play a video there.

This issue is not only with Udemy however, as the YouTube videos also take longer than normal to start playing; It's not only at the start of the video either (whilst waiting for the video to fully load), It's all the time, between every pause I have to wait around 3-4 seconds before It actually start playing.

The issue is clearly something to do with videos but I find it very strange that playing a YouTube video forces my Udemy video to load.

It's been a real struggle trying to get todays course day done, since every time I pause the video I end up having to wait a while or go to YouTube and play a video to make it continue.

I've gone through all the basic troubleshooting recommended for video issues on here and other places: Turn of hardware encoding, lower security levels, enabling autoplay etc etc; absolutely no luck. I've tried disabling extensions one by one, disabling themes, running FireFox in troubleshoot mode, clearing all data/history/cookies/cache, making sure DRM-controlled content is enabled as well as trying it disabled. You name it, I feel like I've tried it at this point... Any suggestions are highly appreciated!

Another thing to add is Chrome isn't having this issue, neither is Safari.

I want to disable overscroll. For those who don't know: it's the bouncy animation when you use scroll using a two-finger gesture past the beginning or end of a scrollable region.

The bouncing is an animation, and with animations disabled on my system, having this animation is an accessibility issue.

I guess I could split this question in two:

1. Can Mozilla please change Firefox so that it doesn't do this animation when animations are supposed to be disabled? 2. How can I disable this overscroll behaviour manually, separately from other animations?

I'm a web developer working on an app running in Docker on my MacBook. Chrome, Edge and Safari trust the self-signed certificate that has been imported into the Mac's root certificate store and have no security issues, but when I try and access the web app, I'm hit with "Warning: Potential Security Risk Ahead" and the error code is MOZILLA_PKIX_ERROR_CA_CERT_USED_AS_END_ENTITY

I really miss Firefox, particularly the multi-account containers feature. What do I need to do so that Firefox will trust my certificate for my local web app?

2 days ago I had all my bookmarks perfectly in my browser and today when I opened firefox today, all my bookmarks were just gone without a trace, this never happened before at all, and even when I uninstalled firefox and reinstall it the bookmarks would still be there, how can I get them back?
