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.

Dear Firefox Support Team,

I recently encountered a problem while using the ChatGPT platform (https://chat.openai.com) in Firefox. The issue was that I was unable to type anything into the input box ("Ask anything" field). The box would not respond to clicks or keystrokes, effectively preventing any interaction.

After switching to a different browser (e.g., Chrome), the problem disappeared, so it appears to be specific to Firefox.

Kindly look into this compatibility issue. I’m using the latest version of Firefox on [insert your operating system, e.g., Windows 10].

Thank you.

Best regards, James Tang

Recently I have had several experiences with captcha when paying for something with a credit card. I check the box saying I'm not a robot, get a green arrow, but then the purchase does not go through. Error message says I failed to satisfy the captcha, even though I was never shown the grid of images. Just now I tried the same operation with the same company invoice using Chrome, and it went through successfully by just checking the box I'm not a robot. This is very inconvenient.

Hello,

I'm facing an issue where my microphone does not work in Google Meet when using Firefox, even though I’ve granted all necessary permissions. This problem is specific to Firefox, as the microphone works perfectly fine in Google Chrome.

I prefer using Firefox because of its convenient screenshot features, but this microphone issue has caused major inconvenience during important meetings.

Kindly help me resolve this issue.

Thank you.

I can login into Xfinity email, but not into the billing section. I've attached three printscreen errors. The 1st is a handshake error as seen in top address bar. The second is a Access Denied error and the third is a "waiting for bat.bing.com"(a tracking cookie)error that can be seen in bottom, left hand corner.

I reached out to Xfinity tech support and was told to try a different browser. I tried DuckDuckGo and that did work and let me login and pay my bill. I told the tech that I would still rather keep on using Firefox. He said "that's something that you would need to take up with Firefox since we now know the issue is with their browser"

How do I get this issue resolved so that I can keep using Firefox as I have for many years now?

Note: Already tried clearing cookies and browsing history with no difference.

In trying to access (log in)Social Security Administration, I received "Bad Request""your browser sent a request that this server could not understand. Size of a request header exceeds server limit" I was able to log in with Chrome. Can this be corrected by mozzilla?

When I do a map search for 'near me' via Firefox, the results are far from where I live. The same search in Chrome produces the correct results. The Default location in Windows 11 is correct. I've restarted and the problem remains

Dear Mozilla Team,

I’ve been a loyal Firefox user for over 15 years, and it’s been my go-to browser for both personal and work-related tasks. However, recently I’ve encountered persistent issues where several websites—especially work-related ones—have stopped functioning properly. I’ve tried troubleshooting steps like clearing the cache, allowing cookies, and disabling tracking protections, but the problems persist.

Reluctantly, I switched to Google Chrome as it currently offers better stability, but it’s been hard to abandon Firefox after so many years. I truly value Mozilla’s mission and privacy-focused approach, and I’d love to return if these issues are addressed.

Could you please look into these compatibility problems? I’d appreciate any guidance or updates on fixes. Thank you for your hard work—I hope to support Firefox again soon.

Best regards, Gustavo

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 had switched to Firefox from Chrome because they banned AD BLOCKERS. But now I have to go back because FACEBOOK VIDEO CHAT won't work ( according to Facebook) because they introduced end-to-end encryption. Can you give me a fix?

The Governor of Poker site gives me an error message when I try to log in with Firefox:

Your browser does not support graphics API "WebGL 2" which is required for this content.

Not a problem with Google, Edge or other browsers.

Graphics Acceleration is turned on.

Any other thoughts?

Ever since I updated last week, one website that I use will not work. Whenever I try to log in to the M&T Online Banking website, it blocks me and says "M&T Online Banking Is Temporarily Unavailable." The app works on my phone and I can log in through Chrome, it's only on Firefox that I'm getting this problem. I called M&T Bank and they confirmed that it's a problem with Firefox. Something is blocking me but I don't know what it is. I am not using a VPN or adblocker.

Hi!

Yesterday, April 5, 2025, my Firefox started displaying this message for every search typed in the browser:

"Our systems have detected unusual traffic on your computer network. This page verifies that it is really you, and not a robot, sending the requests. Why did this happen?"

I tried a few solutions: I cleared the cache, restored Firefox, reinstalled Firefox, restarted the internet modem, reset the computer's DNS using the ipconfig/flushdns command, scanned for malware with Windows Defender, and scanned for viruses and malware with Kaspersky, but the problem persists, both in the normal tab and in the private tab.

I contacted my internet provider, and they said there is no problem on their side.

In Firefox, I always use the default search engine "Google".

When I change the search engine to "Bing", the problem does not occur.

The problem does not occur in the Google Chrome browser, only in Firefox.

I am using Firefox 115.22.0esr (64-bit), Windows 7 operating system and internet connection via network cable. I only have one computer connected and I don't use VPN.

Please, can you help me?

Thank you!

Can you please help me solve this issue. Thank you

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.
