I-Firefox Community Forum

I have a new laptop and am using Firefox as my browser. But when I'm on Facebook, go to chats it says that video chat isn't supported by this browser. Does Firefox not allow this? I've tried going to permissions to allow Facebook to access my camera and microphone, but unable to do so. How do I use the video chat feature in Facebook chats?

When I play YouTube videos in Firefox, the video stutters and drops frames, even at 480p. Audio keeps playing normally. This does not happen in Chrome on the same computer. The issue started about a week ago. I’m using Firefox on Windows 11 on a laptop. Restarting Firefox did not fix it.

Or is the only option - as a web developer, to make duplicate css flags?

I.e: https://developer.mozilla.org/en-US/docs/Web/CSS/Reference/Selectors/::-webkit-slider-runnable-track & https://developer.mozilla.org/en-US/docs/Web/CSS/Reference/Selectors/::-webkit-slider-thumb Where firefox supports the behavior, but under different flag names https://developer.mozilla.org/en-US/docs/Web/CSS/Reference/Selectors/::-moz-range-thumb & https://developer.mozilla.org/en-US/docs/Web/CSS/Reference/Selectors/::-moz-range-track

Im also looking for recommendations on barebones/simple parsers that can help make my html/css/js more compatible without messing up the code too much. Im hoping to avoid having to use a build system.

Thank you

In Firefox, the animation exhibits performance issues like stuttering, particularly in elements that rely on animateTransform and animate for movement or opacity transitions. This issue is not present in Chrome, where the animations run smoothly without any noticeable lag.

Expected Behavior: The animation should render smoothly on both Chrome and Firefox without any stuttering or lag, providing a seamless experience for users.

Steps to Reproduce:

Open the provided SVG code in Firefox.

Observe the animation, particularly the elements with animate and animateTransform attributes.

Notice the stuttering or lag compared to the smooth rendering in Chrome.

Hi Google Maps all of a sudden is not showing the names of places in Firefox. When Google maps loads initially the names show for about 1 second and then disappear.

 I am on a Surface Pro 9.  

Google Maps works fine in Chrome.

I have already tried disabling extensions, clearing cache, and ensure the performance is set to run normally. 

What else can I do to fix this?

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.

Hello,

I am having an issue with my Instagram account on PC (web version).

I can log in successfully, but after logging in the page does not load. It only shows the Instagram logo and stays stuck on the loading screen. Refreshing the page does not help.

Important details:

Instagram works normally on my mobile phone (app)

The account is not blocked or disabled

I changed my password successfully

I tried different browsers (Firefox, Edge, Chrome)

I cleared cache and cookies

I tried private/incognito mode

The problem only happens on PC, not on mobile

Because everything works fine on my phone, I believe this is a problem with the Instagram web version or a browser-related issue on your side.

Please check my account and let me know how I can fix this or regain normal access on PC.

Thank you for your help.

Summary: Uploading a file to a custom webapp with Chromium (Edge) works but consistently fails in Firefox. In Firefox the request is created, and times out. The server receives no file and logs “missing file.” The same webapp code is running on both Chromium and Firefox.

Environment:

• Next.js app (pages/api route)
• Endpoint: POST /api/file-upload
• Client: fetch(url, { method: "POST", body: FormData, credentials: "include" })
• Server: export const config = { api: { bodyParser: false } } + multipart parsing (formidable)
• Edge/Chromium: Version 141.0.3537.85
• Firefox Version 147.0.3 (64-bit)
• OS: Ubuntu 22 / Linux

Steps to reproduce:

1. Create a FormData object and append a local file:

  const fd = new FormData();
  fd.append("template", file, file.name);
  fetch(`/api/file-upload`, {
    method: "POST",
    body: fd,

1. In Edge/Chrome, upload succeeds. Server receives multipart body and parses the file. Actual behavior in Firefox:

• Transferred: 0 B
• No response status/body
• Client times out (Upload times out)
• File upload request received
• No bytes read server‑side.

Evidence:

• Edge request logs:
  • content-type: multipart/form-data; boundary=----WebKitFormBoundary...
  • bytesRead ~1.69MB
• Firefox request logs:
  • Transferred 0 B
  • File upload missing file field

Notes:

• Client FormData is valid; we log file.name and file.size right before fetch.
• There is a CSP report‑only warning (frame‑ancestors) when using a fallback iframe approach, but we are not using iframe in the failing case.

Question: Is there a known issue where Firefox blocks or fails to send and multipart/body can be stripped before it leaves the browser? Is there a recommended workaround that does not rely on browser sniffing?

New sites online (foxnews.com, newsmax.com and others) will not load comments. Had to remove shield and try several things. Still a problem. Everything before 146.0 worked. I'm sorry I did the upgrade as all this takes too much time.

Hello,

The fonts are not rendering properly on few websites, example(apnetv.xyz), everything was working fine with stable release of v146.

The beta versions were having the same issue, i assumed it was related to Beta releases, so I switched back to stable one. However now firefox has released stable v147, the issue persists. Kindly fix it.

Regards, 4hm3d

Since upgrading to 147 last night, ChatGPT does not work and there are issues with other websites (Amazon side bar). Numerous people reported it on reddit. Any suggestions for a fix?

Differences in the display of Firefox and Chrome styles on the website https://aistudio.google.com. In the first photo, Chrome and the styles look as they should, but in the second photo, Firefox and the styles do not work. I understand that this is most likely the fault of Google, which has prioritized optimization for Chrome over full cross-browser compatibility, but are there any solutions to fix this?

Hi this can anyone shed anylight on this please? I was using Facebook earlier today with no problem then now it won't run nor open yet it runs fine in Google Chrome. I've cleared out the Cookies ect and re-tried but its not pitching anything.

Many thanks Rob

Hello,

I am having an issue where my google account half logs out after every session. My gmail remains logged in, but google search does not. Google drive (and this is the main issue), is stuck so that it can see the files of my account, but insists I'm not signed in.

When I attempt to login and retry nothing happens and it remains in the loop. Before today I have been able to open documents only accessible when signed in on google drive by going to the direct link. This is now intermittantly thinking I am not signed in but mostly working.

Things I have tried:

• Troubleshoot mode does not fix this problem.
• My firefox is up to date.
• I have seen this with no extensions or ad blockers.
• I have seen this both with and without cookies from google allowed.
• Screenshots attached from when I talked through this with google support. They said it was a problem on your end and can't do anything.
• This can be solved by logging out of all accounts and back in. But this is not an acceptable solution.

I am trying to get on an website but it will not let me it keeps saying to verify url or contact support i have updated both laptop and desk top and for some reason this one particular website will not let me have access is this an issue you that you can help me with.

I use default browser and suddenly Firefox can't load website Shopee Try chrome and it load shopee normal. Have try turn off all extension for shopee site. Hope someone can help

The website commonly used by Arizonans to make filings for court, will not work properly with Firefox, even after turning off Enhanced Tracking Protection. I had to use Chrome instead.

When I click on a link in emails to open in browser if email has display problems, it opens a blank webpage and a small window that I clicked on OK reappears with Firefox as my default browser. See attached screenshot. If I select Edge to open the email, it works fine.

Please address.
