In Firefox, a lot of my pages are not loading at all...the tab just shows that the website page is loading but it never does. The menus of the website will appear, but pages are not loading. This is not happening in MS Edge. I prefer Firefox, but lately have had to go to MS Edge to load pages. What could be happening?

Hi,

I’m facing an issue with my website’s fine checking tool on Mozilla Firefox. My website is evgfinescheck.com , and the tool works fine in some browsers, but on Firefox it doesn’t load properly and sometimes shows an error.

I am already using the latest (updated) version of Firefox, so the issue is not due to an outdated browser. The tool either fails to fetch data or doesn’t respond as expected when users try to check fines.

I’ve checked basic things like internet connection and browser updates, but the problem still persists specifically on Firefox.

Can anyone guide me on:

What could be causing this compatibility issue? Are there any common JavaScript, API, or CORS-related problems specific to Firefox? How can I debug or fix this issue?

Any help would be appreciated. Thanks!

When I try to log onto Facebook via Firefox I can see only three articles and after that everything goes blank. I don't have that problem when I use Edge. What can be the problem?

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?

lloyds bank uk has always worked for last 16 years, does not now the dialog box they produce on a change details process should end up with a code they generate. nothing appears so i cannot access my account even after going through on helpline. their suggestion is that i should change to Chrome!

I need my gmail account but I cannot sign into it, it wants me to start a new one, but that will not do at all. I will wait for a week to see if you can rectify this problem.

Bonjour Depuis un certain temps, je ne sais plus quelle mise à jour, j'ai des erreurs 406 à répétition avec Firefox. C'est très pénible!! ADBlock + is disabled Celà ne se passe pas, pour les mêmes pages avec Edge. Que faut-il faire? remettre Edge en navigateur par défaut? J'ai des exemples, mais je ne sais pas si je peux mettre les liens ici sans être censuré.

I run 115.37.0esr (64bit) on a Windows 7 pro system. Recently I cannot look at either Home Depot or Lowes websites. I can see them on Chrome. I have no other trouble viewing websites, just these two. Can anyone tell me why and more to the point tell me how to fix it.

Since the last few days weather.com will not work with my version of Firefox. I use 115.37.0esr version of Firefox. Since the last few days Weather.com seems like it is loading and displays the page correctly for half a second but as soon as the page appears, it disappears leaving a small message midscreen that says " This page couldn’t load - Reload to try again, or go back."

I tried turning off my adblocker but that made no difference. Anyone got any ideas? I really like weather.com. It's one of those nice websites that are like when the web was new and was just a useful thing for everyone.

Since the last update when I go to YouTube and I choose my Home or YouTube icons so I can watch videos I will see the list of videos they are offering for just a flash and then they disappear. I still have all the things across the top and down the left side of my screen that YouTube always shows, but there are no videos to be seen. It's just white space. After turning off different items in my Malwarebytes to see if it was a problem with them (which it did not seem to be), I decided to try YouTube on Safari to see if it was a FireFox issue. YouTube worked perfectly on Safari. I've been looking through settings to try and figure this out, but I'm having no luck. Any suggestions are appreciated.

I have gone to Menard's several times and have tried to open a dog kennel item so I could see it bigger and in a single item view. Nothing happens when I click on it like it did before this last update!!!!!!!!!!! I get so tired of these program people change so much that i mess up how a person had used the software before they mucked it all up!!!!!!! In the last week I had the Firefox update, and two others an all of them have been changed so drastically nothing works like it did before the updates. MY REQUEST IS LEAVE IT THE SAME AND DON'T MESS WHEN HOW WE HAVE BEEN USING THE PROGRAM UNLESS WE WANT THE NEW UPDATE!!!!!!!!!!!!

Windows 11. I am the web manager for tunbridge wells u3a. The site is hosted by the national u3a and uses their templates etc. On edge and chrome, it works fine, but not on Firefox. Several months ago, the page operations (save, open, change, etc took a few minutes to complete, with the message bottom left about waiting for the host site. All of the usual cache clearing, reboots etc made no difference.
