Recently, when I try to play a video on YouTube on Firefox, there is a flickering brightness effect (some aspects of the video seem to flicker bright and dark quickly) which is distracting and makes it difficult to watch anything. The effect persists even when launching in troubleshooting mode, and disabling hardware acceleration and restarting appears to have no effect. I have also been unsuccessful refreshing Firefox. Nevertheless, this issue is absent on Safari and Chrome when watching the same video.

Watching a solid colored video like this helps see the issue best, if it is happening to your device: https://www.youtube.com/watch?v=hJmFYZEcpZA The brightness switch is visible even when pausing the video.

When I find the same video two different places (ex: the Apple Sept 12 Event on Apple's site, versus on YouTube) only the YouTube video has the issue. However, I can't find any settings to change on YouTube to help this.

I am unable to login to my Prescription provider's website (which I do every day). Problem started Sunday and still persists.

I am able to login using Chrome, so I know the website is working properly.

Help - I DO NOT want to use Chrome.

Hey!

For over a year some webpages show up blank in my Firefox browser. They all work fine in Inkognito/private windows.

I have tried emptying cache etc. Running Ventura 13.6.

One page recently stopped working and show: Application error: a client-side exception has occurred (see the browser console for more information).

www.pinterest.com is completely white.

Facebook.com shows up fine but does not work properly.

Any instructions on exactly what to do?

I have screenshots of the error I receive when logged into the website. The support staff from LawofSelfDefense.com says everything on their side says I should be receiving audio and video. I have checked DuckDuckGo privacy settings and they indicate that their product is not blocking anything from the website.

I used MS Edge this morning to stream a live episode and it works! I do not want to access these streams using any MS products/software. Something in Firefox is preventing me from Live video and Chat activity on the site. What can I send you to help me fix this problem?

Hello

The google search bar on the home page has increased in size and my extensions/add on such as cache cleaner and adblocker do not appear on the toolbar even though they are turned on. I tried refreshing Firefox but that did not solve the problems. Thank you

When a bookmark is made, there is no option anywhere to add tags using windows 11 - I had no problem with tagging bookmarks using Firefox in windows 10, but that option is not showing up for me in windows 11. I have refreshed Firefox with no success to try to correct this situation - thanks in advance for any help you may provide – del

Youtube and Twitch both have a delayed response to un-muting. After turning on the audio, it takes about 4-5 seconds to hear any audio. Youtube has long load delays each time rewinding or pausing. I tried on chrome and I didn't get these issues. I also already cleared cache and history.

Hello, After the last update (September 2023), I've been having issues with in-game ads being blocked, even with exceptions added and Advanced Tracking options turned off.

I got them to work for a couple of days, but now they're being blocked again. I've cleared cache & cookies, restarted Firefox, reset permissions, all have not helped.

Please advise!

I'm using Windows 10 on an HP PC screenshot of website permissions included

I have many hundreds of Bookmarks, maybe thousands, in a lot of Folders. However, a search will NOT find a Folder with the Search name.

Is there any way to get around this omission?

On a site with a menu along the top the rightmost item is missing, and only in Firefox, not Chrome or Edge. It happens on various pages with the same menu setup. I cleared cookies & cache, turned off extensions, no luck. See attached image. What could the problem be ?

I Closed the browser and forgot that I had a private one open too. When I went to open the main Firefox window up, my previous session was wiped! I already tried the right clicking plus sign method to no avail. It just brings up the one I had after searching how to bring back the session and then accidentally closed the browser after. Any tips on how to get it back? Why does this happen just because you have a private window open??? Change that ASAP!

I ran a loghttps://pastebin.com/jydVHHs0 of playing a youtube video mediaencoder? not sure if encoding issue or something else

The videos take a long time to play. I upgraded my system recently and was removing and reinstalling audio-related utilities with DNF.

When I login with United Health Care and the information that I need will not show. It did previously. So I had to use Google to get into United Health Care. Should I uninstall then install Firefox?

Is Mozilla Firefox using SEDO GmbH, sedo.com?

I have used a custom html file as my homepage for years and while I can get Firefox to accept it as my homepage, I can't for the life of me figure out how to make it so when I open a new tab it goes straight to said custom page. I've tried multiple different add-ons for Firefox and none have worked, and I've checked multiple different support questions here and am still unable to figure this out.

As per subject. After i close FF - and it is no longer showing as an app in Task manager. When i try to restart it, it says it's still running and i have to ask it to close FF before it will open it again. AFAICS It happens randomly.

It may be relevant that when using CCleaner, it often (randomly) hangs when cleaning FF internet cache and says FF needs to be closed when it is already closed and does not appear in task manager. If i ask CCleaner to close FF, the application hangs.

Less likely perhaps to be relevant: i got a rogue change of Favicon on one site. I eventually deleted the relevant file hoping the Favicons would repopulate. Most have, but many haven't including hotmail and protonmail sites.

There seem to be many causes/solutions to FF hanging but i thought these specific circumstances might make it easier to suggest what the problem is exactly and how to fix it.

Thanks.
