Hi! I'm experiencing an issue where videos on YouTube stutter or play choppily when using Firefox. This happens even when the internet connection is strong and works fine in other browsers like Chrome.

Here’s what I’ve noticed:

The issue occurs on both 720p and 1080p videos.

It’s more noticeable when switching to full-screen mode.

I’ve tried disabling hardware acceleration, but it didn’t help.

Firefox is up to date (v126.0).

I’m using Windows 11 and have an NVIDIA GPU with the latest drivers.

I’d appreciate any suggestions or fixes. Thanks in advance for your help!

I have no ability to connect to the IRS.gov account log in page. When attempting to do so, the link reverts to a maintenance page, with the hopeful message: "We apologize but there seems to be an issue completing your request. Please try again in a few minutes." An error URL is also attached.

This is not a new problem and has been ongoing for over a year. I have found several messages in the Mozilla support system describing the exact same problem from different users. There does not seem to be a fix that has been found. The information that I have found regarding the IRS website does not suggest that it will only work with Chrome or Chrome based browsers. But I can easily use the site with Edge.

There are several sites that I am unable to access with Firefox that force me to use Edge. I understand that Firefox has its security idiosyncrasies. But As this number climbs, and to include what are public facing government sites, a question I will soon ask is why use the Fireofox browser?

for some reason my youtube tv claims it needs to be updated so can not watch tv in settings it claims to be the latest version 115.29 but google claims it is 144.01 so have no clue how to update if that is why I can not watch tv trying to ask mozilla is pointless with there b/s excuses which is part of firefox

You know, I'd love to stick with Firefox as my main and only browser on my desktop. But it gets irritating when suddenly I can't use a web application or YouTube videos (like today) won't play or anything that forces me go go back to Chrome because THAT at least works consistently.

I'm having trouble getting AOL, my homepage. When I log on to Firefox, I have an instant load to AOL. It doesn't load and I see files waiting to download in the lower left corner of the screen, but they don't. I have no problem with Microsoft Edge performance but haven't tried to access the homepage. Any suggestions?

Sound and picture do not sync

Sound and picture do not sync when I stream TV using Firefox 133.0.3 64bit, but works perfectly with Edge and Chrome. Sad because Firefox is my favorite browser, so I hope you can help me solve this problem. My PC Intel I7 24gb RAM internet download speed 150gb

On the Dallas Theological Seminary site, only this site, suddenly I'm unable to login - it doesn't recognize my password. Nor will it allow me to make a donation. I complete the donation form and it just keeps going round and round "processing" but never does it. I cleared my cache, re-started my laptop, made sure Win 11 is updated, still same problem. I did not try disabling extensions because they haven't changed in a long time. I opened it in incognito window and was able to login and make donation there. However I could not log in to my Gmail account from there. I went to a different laptop that runs Opera browser and logged into DTS just fine. This problem just started. Until recently I had no trouble with this site.

i am trying to play a game on cool math games and the game keeps hanging. i also have issues on another site where the video player indefinitely loads. and yes i have cleared cookies and site data, disabled all extensions, started firefox in troubleshot mode, disabled hardware acceleration. but the only thing that fixes the issue is using another browser.

how to reproduce

1: go to this url: https://www.coolmathgames.com/0-jacksmith 2: load the game and start a save 3: skip or wait through the dialog (i did both) 4: when the dialog ends you should be stuck with a folded piece of paper on the side of the screen when the animation froze. loading the save will also cause a freeze

When I tried to login to My Social Security it said I do not have access to that account so I contacted Social Security for help and they determined that it was the Firefox browser and asked me to open Microsoft Edge and try to login and that worked perfectly. Why is Firefox preventing me from logging into Social Security.

I use the website MassageBook.com for my business scheduling and communications.

Yesterday, everything worked fine. Today, for some reason, I clicked to log in through Firefox and it got stuck in a loop, returning to the log in page but never actually logging in. I contacted MassageBook and the suggested using Google Chrome to log in. This worked perfectly!

My preferred browser is Firefox, but it's not working for my most used website! I would appreciate this being looked into and corrected ASAP!

I can only open 2 tabs while using my Seeking Alpha financial program on Firefox browser. If I try to open a 3rd tab the Seeking Alpha program will not open. This issue just started within the past few days and doesn't occur when using Seeking Alpha program on MS Edge browser. Hopefully you can fix this problem quickly otherwise I will have to start using Edge as my default browser.

Up until about six weeks ago, I could access a provider statement through a function on USAA.com bill pay service. I now see an empty pop up screen or an error message that the page is not available. I tried suspending use of the VPN without success, then tried another browser (Chrome) and the function is available. Is this a settings issue or something else? My preference is to use Firefox as a browser.

I can't watch Twitch live stream and videos after updated.When I watching live stream on Twitch, the stream start showing some old tv effect but in colours green. I thought was Twitch problem, then I changed to watch video from my college by using their website. But it still has that effect. But I can watch Youtube videos with no problems. Then i changed to use Microsoft Edge to watch Twitch, surprisingly with no problem. I already updated to the latest version in Firefox. Can anyone help me Please. Thank You

I WANT TO UNDERSTAND WHY MY SEARCH ENGINE WORKS PERFECTLY BUT ANYTHING I TRY TO OPEN A LINK TO CERTAIN WEBSITE LIKE X (FORMALLY TWITTER) IT DOES NOT OPEN, INSTEAD I WOULD GET A MESSAGE LIKE "PROBLEM LOADING SITE". BECAUSE YOUTUBE IS WORKING, FACEBOOK AS WELL. AND ASIDE X, I CANNOT EVEN OPEN WIKIPEDIA

McAfee WebAdvisor extension has stopped working on Firefox. It works normally on Microsoft Edge. I've always used Firefox and rely on seeing those green ticks when searching through Google. Why doesn't it work on Firefox anymore?

My organization uses Box Drive for file storage/transfer. I recently upgraded to an ARM-based PC (Microsoft Surface) which the Box app does not support, forcing me to use a browser to access my files.

When I upload a file to Box via Firefox, it repeatedly uploads the same file until I close the browser. I only noticed this after coming back to the tab and noticing that the PDF I uploaded was on version 1,937 and counting. I tested another file and observed the same behavior.

The behavior persists when using a private window with all extensions disabled.

The bug does not appear to affect Chrome: files upload once as expected.

In Firefox, other services such as Dropbox and Google Drive are not affected, only Box.

Anybody else experienced this and found a solution?
