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'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.

Hello i have a question i had to du a format of my pc and clean install but when i installed mozilla and did sync it did not auto open all my open tabs on same but new device i have the older device and able to open the tabs one by one but i can have alot of open tabs even over 30 but i can't find the option to open all tabs from divrent device on curent one.

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.

After updating the browser from 115.03 to 116.02 it is lagging like crazy and the Cpu usage was extreme. But when i switched back to 115.03 everything was just fine. I think the new update is not good, i will say it is pretty bad. Please solve this problem with newer update. Thanks

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?

firefox monitor does not allow me to sign in using dashlane password manager. Every other website responds by either filling in the name and password, or asking if I want to use Dashlane data. Please help. thanks

Hello,

I've been facing this problem while i try to download something from internet. I am trying to set firefox to ask me every time where to download the file. But firefox automatically downloads it on desktop and opens the file. I know i'm supposed to select "Always ask you where to save files" but I see no radio button beside the option "Save files to". I've attached a screenshot of my options menu. Is there any solution? My firefox is updated to latest version (115.0.3 64 bit)

Best Wishes!

Hi, my problem is as follows:

I have tried to login but i don't have auth code(my google auth doesn't have firefox on it anymore) or recovery key(Windows 11 install reset my pc event tho i asked it to keep my date/files). Anyway at all to get back onto that account? I have access my emails and my login details are correct.

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?

Hello! I completely restarted my computer so it is functioning like new one. I managed to log in into my firefox account which I have used previously and had synchronized all data.

After connecting to my account there is no data after synchronisig - no history, no tabs, no passwords and accounts details.

Please let me know what is wrong.

Regards, Marcin

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.

When I am leaving the browser idle for long periods, I get crashes.

Any help would be appreciated.

When I open Firefox on my Windows computer the Icon appears in the taskbar below the page, and the app is open, but not window opens and appears on my screen. I have to right click the icon in the taskbar and click the app again to get the window to appear. Can you help me find out the cause of this issue?
