Is there a webkit compatibility mode to make Firefox try to listen to -webkit css flags?

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-runnab… (funda kabanzi)

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

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.

recent firefox update can no longer copy and paste when creating a blog post in Squarespace, I have been using squarespace for around 15 years for my websites and I have never seen this issue, Firefox 15.1 installed and all of a sudden when trying to create a blog post in Squarespace, when I right click a text box pop up and it no longer says paste so I can no longer copy and paste text - this is more than a little annoying, you will not be surprised to know that I am now using Chrome to create my posts, there is no issue in chrome. I am a firefox geek! how can i solve this problem, I just did another update from Firefox, the issue remains I have been using computers for 40 year so I am not a novice but software glitches, I am lost

Firefox multipart/form‑data upload stalls (0 bytes sent) to Next.js pages/api endpoint — works in Edge/Chromium

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?

Moderator note: This question has been edited to correct the formatting.

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.

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.

I use the web client of Outlook for my work email. However, I've run into an issue: while I can log in through Firefox, every so often (and lately it's been quite often) I launch the Outlook webpage, and all I get is just a bunch of code (see image). The only thing I've found that makes the page work again is to clear all cookies and cache, and clear the start-up cache, and then launch Firefox again. Obviously, this is very annoying, since I have to log in anew every time (and use 2-step verification, etc.). Does anyone know how I might fix this more permanently so I don't have to keep clearing all my cookies and logging in all over multiple times a week?

  • OS: Windows 11 25H2 (26200.8037)
  • Browser: Firefox 148.0.2
  • Camera: Logitech C925e

When I go to a meeting on meet.google.com, Google Meet says "Camera is starting". My camera light flashes and then stays on. However, Google Meet is unable to connect to the camera.

Upon closing the tab, the camera light stays on and the camera is unresponsive to all apps. The camera must be unplugged and plugged back in to work again.

The issue does not exist when I go to webcammictest.com in Firefox or in other desktop apps. The camera works correctly on meet.google.com when I use Chrome.

I have tried removing camera and microphone permissions to meet.google.com and re-granting them. I have tried deleting all meet.google.com cookies and storage.

Hi everyone,

I am experiencing a persistent rendering issue on my company's website when viewing it through Firefox (v123.0+). The site features heavy-duty industrial units and detailed technical specification tables, which involve several high-resolution PNGs and large CSS grids.

The Issue: When scrolling through our product gallery, the images seem to "flicker" or disappear momentarily. This does not happen in Chrome or Edge, which leads me to believe it’s a Firefox-specific rendering bug related to hardware acceleration or the way Firefox handles large object-fit: cover containers.

Live URL for testing: [https://portaking.pk/|https://portaking.pk/]

Details:

Flickering: Occurs primarily on the "Porta Cabin" product pages where we use an image slider.

Console Errors: I am seeing a "Layout Force Reflow" warning in the Firefox Console that I can't seem to replicate in other browsers.

Troubleshooting: I have tried disabling all extensions and clearing the cache, but the jittery scrolling persists on this specific layout.

Is there a known CSS conflict between Firefox’s rendering engine (Gecko) and modern WordPress grid layouts that might be causing this? I want to make sure our clients using Firefox have a smooth experience.

Thanks for any insights!
