YouTube is playing 4K videos like they are in slow motion. If I lower the quality they work fine, but switch back to 4K and it's slow motion stutter-fest again. I have seen several topics about this but it's still happening to me despite all of the "fixes" I've tried. This is a list of everything that I've seen and tried, and not a single one or any combination of them fixes the problem for me.

In about:config I tried changed the following to False: gfx.webrender.layer-compositor media.av1.enabled media.wmf.dxva.d3d11.enabled

Tried uninstalling all extensions.

Tried a complete uninstall and reinstall of 149.0.2 with a fresh profile instead of updating from 148.0.2.

Tried installing uBlock Origin and used the following rule: ||www.youtube.com/web-reports$xhr

Tried unchecking the uBlock "Quick Fixes" filter.

Tried disabling hardware acceleration.

Tried disabling DNS Over HTTPS.

All that said... what DID fix it was reverting back to Firefox 148.0.2. I tried again to update from that to 149.0.2 using the FF built in updater but the same issue immediately came back. Zero issues at all playing 4K YouTube videos on FF 148.0.2 or the latest versions of Chrome and Edge. Issue is ONLY on FF 149 and 149.0.2.

The links on the site tasteofhome.com stopped working recently. When you click on them nothing happens. If you load the same page in chrome they work fine. Any suggestions? Or is this a bug Sample URL https://www.tasteofhome.com/recipes/chicken-and-bows/ but there are many more

Dans free.tv pourquoi la suppression des sous-titres ne fonctionne pas problème Mozilla ou Free.tv ?

For quite some time now, I am unable to sign in to my account at CanadianTire.Ca I get an error. The signon process goes to CustomerAuth.Triangle.Ca for the email and password input. When I click "Sign In" the return message is a yellow triangle followed by the word "undefined" (see attached).

All other browsers I have (Brave, Chrome and Edge) can sign in without issue.

I noticed that other users have the exact same issue. I have tried all solutions I could find. The browser is up to date as of today (150.0.2 64 bit). I tried troubleshoot mode, clearing the cache, deleting cookies, history .... On the web site I turned off ETP for CanadianTire.Ca and CustomerAuth.Triangle.Com.

I have used Firefox since it was v0.93.

My copy of Firefox updated about 1600 local time yesterday. At this same time Facebook could not be accessed, just get a blank page. Tried clearing history, but still not working. Windows 11.

When I play YouTube videos in Firefox, the video stutters and drops frames, even when set to 480p. The audio continues to play normally. This issue does not happen in Chrome on the same laptop.

The problem started about a week ago. I’m using Firefox on Windows 11. Restarting Firefox did not resolve the issue. I’ve attached screenshots for reference.

Today following a brief power outage I was no longer able to sign in to AOL with Firefox on my desktop computer. I am able to sign in to all other apps with no problem. I tried clearing my cache, restarted Firefox, restarted my computer and spent 30 minutes on remote desktop access assistance with AOL trying to fix the problem with no success. I can log in to my account using Chrome on the desktop computer and can log in with no problem using my Android phone but can't log in using my desktop computer with Firefox. I've verified that my Firefox version is updated. I am running Windows 11 Pro.

I would greatly appreciate any helpful advice.

I have had access to TastyTrade thru FireFox for years. Within the last two days I am unable to log on. When I click on the link the screen goes all white and the page will not open. When using Edge I am able to get logged in but not thru FireFox which is my preferred browser.

As of recently, I have problems with Firefox that do not happen in other browsers. But Firefox is my favorite, and I'd like to have this solved so I can keep using it.

In Zendesk, there is an option "Print ticket" which should open Print dialog and we then can print whole email to PDF. This worked for years, but as of recently that dialog simply does not show. I tried change Firefox settings for printing, but problem remains. Attached is a screenshot how it looks in chrome, and how it used to work in firefox.

As from yesterday, April 17, Firefox will not load correctly https://m365.cloud.microsoft page. It loads, but no element reacts when clicked. I cleared cache, cookies, removed extensions, refreshed firefox, but to no avail.

Thanks for the help!

Hi, I need help with an issue related to how my website https://forganica.com/ loads in Firefox. The site works fine on Chrome and mobile browsers, but in Firefox some elements are not rendering correctly and the layout shifts on scroll. Is there a recommended way to debug layout or CSS rendering issues specifically in Firefox? And is there any Firefox-specific setting or developer tool I should check to understand why my site behaves differently?

I am 81 years old, ad not a tech genius, but I can no longer access my memory photos that microsoft one drive sends me every day. It did work before, but now I get a blank screen. Microsoft help tried the edge system, and the pictures came up, but on firefox, I now get a blank screen. I do not want to change browsers

Hello,

I'm having an issue with my website, https://bitlifeapk.org/, when it's opened in Firefox. Some pages appear to load more slowly than expected, while they seem to work normally in other browsers.

I've already cleared the cache, disabled extensions, and tested on different devices, but the issue still occurs. Has anyone experienced something similar or can suggest steps to identify whether this is a Firefox compatibility issue or something I should fix on my website?

Thank you for any advice.

When using BT Mail i am unable to input email address from drop down box which appears when typing intial first letters.

I can do this when using Edge.

I have updated my browser to latest version. Have also contacted Bt and have been advised that the issue is your browser. My wife has a chromebook and has no issue with the above problem.

Please advise.

Hello

Since couple of days i cant login to Freshservice via firefox browser, on my Windows machine, my MacBook, My Windows 365 Cloud PC. As soon as i try to login i get the and error without any explanation.

I have clear cache, cookies, reinstall Firefox from scratch but still the same issue. On any other browser i could login normally.

Please help Lukas

after the last Firefox update the zynga game Farmville 2 will not load. It gives me a screen to fix mentioning chrome..but all efforts to manually fix referencing Firefox have failed. Odd that I can load the plain Zyngagames.com on Edge but it seems they too only load a "local" game that is not connected to any network. Help also mentions to make sure I allow to redirect but that "Options" feature to do so is not there. In fact it seems like the Firefox menu system is even much different and expanded. I will add the screens I have tried etc. Pop ups are allowed, turned off enhanced etc. but cannot find any reference to "third party redirects" Any suggestions are appreciated.

This message "We are experiencing some temporary issues. The market data on this page is currently delayed." display by Firefox every time I get into finance.yahoo.com recently, but not by other browser. search the message online and follow the steps try to solve the problem and not success.

Last week we lost the progress bar at the bottom of videos on Prime Video. When I cursor over the bar it returns Infinity:NaN:NaN. Switching to MS Edge and the progress bar appears as normal. I get the same results in Firefox on both my PC and Laptop. I have updated and reinstalled Firefox to the lastest version. I have NOT added any new extensions in the last year.

Hello again. Re my very recent post about a game on facebook functioning very slowly after the latest update, I now discover a worse problem with a word-game on a different site that I have also played for years on Firefox. Basically, after the new update, I find that I am no longer allowed to complete a move. Given the now 2 problematic situations I have, do I now with great reluctance have to abandon Firefox?
