As of 7/10/2025, Xfinity Streaming does not open through Firefox. I much prefer Firefox to any other browser so I am a little mystified as to why all of a sudden Xfinity Streaming does not open. I receive my Comcast email through FireFox but when it comes to streaming content, the Xfinity logo just sits there and does not open.

Updated to esr 128.14 Now Reddit (Redgifs) Hosting site for gifs crashes Firefox and cripples my PC. I've tried restarting in safe mode, then refreshing Firefox. Nothing is working. Reddit support just has an issue with the Gifs not playing, but nothing as extreme as what iam experiencing. I believe it may be something is preferences or a codec or something that was changed in the recent update. Any advice/ help would be great. Edit: OS is windows 10 latest updates Amd- Ryzen 7/32gig 3.20 ghz PC. So can handle a little bit of heavy browsing.. FF 128.14 esr Ext- Ublock Origin

       Search By Image 
       Flash and Download Video. 

Even with Addons disabled still occurs. Really at a loss here.

After the last update to firefox the video does not load. there is sound and the side chat chows. the website loads but no video. it is like the video player is being block. all i get is a large purple question mark on the screen ware the video player would be. I tried troubleshoot mode still the same. i removed all addons still the same. I reset firefox back to default and still the same. i have tried other browser and that all work fine.

Version: 115.27.0esr

Hello.

I 'might' be missing a detail but there is no 'X,' in the top right corner, when viewing Google Reviews.

Clearing cookies, closing and reopening the browser, and rebooting the PC are not successful.

.: Hello. A couple of days ago Firefox stopped displaying thumbnails of YouTube videos. I tried YouTube on other browsers and the thumbnails appeared as usual. On Firefox, they've disappeared, but only on my Windows 10 computer. The YouTube thumbnails appear on Firefox on my MacBook. The attached graphic shows what it looks like on my Win 10 computer.

Any ideas on how to solve this would be greatly appreciated. I have also searched the Internet and YouTube for a solution, but was unable to find one that works.

Thank you.

Hi, I am facing a problem where if i start multiple youtube videos and stop the last one that was started, then audio of all the other videos gets paused as well and the video continues, there isn't any change in the volume or in the volume tab icon. I am getting a bit frustrated here, because i tried a lot of options already and most of them just disable all audio. If anything is needed for testing or something, I will add it asap.

The bug exists since Firefox version 131.0 circa, when some things related to DPI had been changed, which I was able to guess because, without touching anything, the size/zoom of the content of the websites were slightly different (bigger). Experiencing this in both Windows and Xfce.

Steps to reproduce:

• Have a custom DPI settings in your operating system.
• Open a new Firefox window.
• Note how the Firefox window height is shorter, so yo can see about 20 pixels of your desktop background. Manually resizing the window and restarting the browser has no effect: the correct height is not remembered.

I've reported this one year ago in the tracker, but no one has yet done anything about it: https://bugzilla.mozilla.org/show_bug.cgi?id=1925284

Am I the only person in the world using Firefox with a custom DPI setting in the OS? I find this hard to believe. Yet I'm experiencing this bug since one years ago. I can't stand using a different browser, but having to resize the window every time is so annoying...

I logged in a few minutes ago and all my bookmarks are gone. It says my bookmarks are empty. I've used Firefox for years and never had this happen. How can this be fixed?

I was notified that Mozilla was unable receive my payment for my VPN. When I opened my account and tried to change my paid subscription, I was subjected to a sign in loop and went back to Profile. I am unable to find an email address for Mozilla support. I am unable to contact Mozilla support for help with this problem. Need help!

For some reason, though I have changed absolutely nothing with my browser, now any time a link is supposed to open automatically in a new tab, it opens in an entire new window. My mouse only has two buttons (Magic Mouse on Mac), so there is no way at all for this to be user error in that regard. The best example is in Gmail when you have multiple accounts signed in, you click the profile picture in the upper right and select a different account which then opens in a new tab. I notice that when I use a fresh profile the issue goes away, and migrating a copy of my existing profile between different Firefox versions (this profile I use in 115 ESR exclusively, I don't use it with more than one version, I just mean for testing purposes here), including forks like Waterfox, all are affected by this issue. Is there something in about:config I should look for to change?

Firefox kept eating my RAM, running dozens of processes. I have gone into about:config and set the dom.ipc.processCount to 1 - then I restarted Firefox and found 5 processes running straightaway before even using the browser. I closed it down and have started it again and now there are 11 processes running with just one tab open. Firefox(9044) Utility(7552) JavaScript oracle Network (15912) Data Decoder (11364) GPU (18744) About pages (12536) Preloaded new tab Extensions (20544) Preallocated (16132) Preallocated (13780) Preallocated (16044)

The problem repeats on three different computers which are not infected with malware. One computer with slightly less RAM I now cant even use Firefox at all (though all other browsers work fine) because the tabs constantly crash due to the high number of processes. Is there any way to set the process limit low in a way that Firefox actually responds to?

I don't know why, but my previous post was removed - https://support.mozilla.org/en-US/questions/1531371 - do you only accept praise here?

to summarise, upon installing the latest release in my new mac, instead of opening the link in a new tab when i right-click on it and press the T key, as was the case on my old mac, it now goes to 'translate this link to x' in the right click menu.

all the boxes in the 'translation settings' are left empty, so why do I still get this useless suggestion? how can I remove it from the menu?

and why is this supposedly 'privacy-focused browser' tracking my IP, which is the only way it could guess the language it suggests I translate my links to?

why are these stupid features not made optional?

In the last 4 or 5 days, I have been besieged by pop-ups from a scam website (I imagine) called giuyt.co.nz asking me to renew my norton subscription or telling me a virus has been found or a trojan detected. None of this is true. I have run scans on my system and there are no viruses and no malware. I have been into programs and deleted one or two programs i dont use, I have cleared my cache I have been into notifications and cleared that. Nothing I can do stops this avalanche of pop-ups (about 1 every 2 minutes). Can anyone help me please?
