Firefox Community Forum

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?

When I do a search on firefox I keep getting the following error and have to go through the CAPTCHA BS.

Our systems have detected unusual traffic from your computer network. This page checks to see if it's really you sending the requests, and not a robot.

This just recently started happening. I'm getting very tired of having to pick out crosswalks, or motorcycles of buses.

This doesn't happen when using Chrome. May have to ditch firefox!

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.

Starting on June 9 2026 my Rockland Trust banking website will not open also other bank websites not opening or take several minutes to open, also other websites not opening. All these websites opened before June 9 2026. I have done all the recommended steps even uninstalling an reinstalling Firefox. What did Firefox do, as I had made no changes. I can open all these websites on other browsers, Google Chrome, Microsoft Edge, etc. I want to keep using Firefox but I can't if websites won't open. Clare O'Brien

Client emails me a URL that is an invite to his MS Teams meeting. I click on it in Firefox and I get a pop up box that states I don't have an App and wants to direct me to the MS Store. I have a MS365 License....

I have already placed 7 MS recommended URLs in the FireFox "Allow" List

When I copy and paste the same hyperlink into MS Edge everything works the way it USED to work in FireFox....

What changed and what do I need to do to get back to "As Desired" (in FireFox)

Yesterday, Facebook started to take longer and longer to load a page. Whenever I tried to post something and it took forevahhhh for it to show up on the timeline. I had to reload and repost several times since yesterday. All other websites are loading up just fine, but Facebook has taken as long as 30 seconds, sometimes even more before it refreshes a page.

Then.. it got worse. All I could see was the Facebook logo in the middle of the screen and nothing else.

Then it got even worse. As of this morning, I can't even get any results when I google Facebook! I put Facebook into the search bar, click return -- and nothing happens, absolutely nothing.

I'm not seeing any problems with any other website. I have already restarted my modem. I have already cleared out the cache and the cookies. I have restarted my laptop three times. I even looked up Downdetector, but there aren't any problems with the website in general.

Those are all the solutions I've found when searching about this, but the problem is only becoming worse, with everything I try. If there's something I need to change in Facebook settings, I can't do that, because now Facebook is completely inaccessible.

This is only happening on my laptop. Mobile is fine.

facebook loads extremely only on firefox. I have turned off enhanced tracking protection which only makes slower ??? Edge has no problem what so ever. Other sites on firefox are not as slow but are still slow. May have to stop using firefox , its very annoying.

I invoke Face Book but it FB page asks me to log in. Will not accept my user and password. Also You Tube is unstable. Only when in Firefox. Other browsers are OK, I can go straight in to site on other browsers.

I want to be able to make voice and video calls via facebook messenger using my PC camera and microphone but, the message I get is that "voice and video are not supported on this browser (Firefox/Mozilla) . It is supported on other browsers. I really don't want to switch browsers, I love firefox. I did find a couple possible fixes via advanced WebRTC settings but everything seems fine, i.e. it is clicked on true not false. I need this soon, can we get settings changed?

I am running the latest firefox version 147.0.3 64-bit. Gmail opens and runs fine on duck duck go and brave. Cannot find any info on how to solve/fix/override/whatever on "numeric code 4" but seems like other folks experience, too. I appreciate 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?

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.

I cant sign into wellsfargo.com with firefox, I CAN sign in with my Avast browser. I have turned off enhanced protection, cleared cache and cookies, restarted my computer. I have called wells fargo and they have informed me that they cant see the sign in attempts and that no blocks to my account were there.

Recently, I wanted to look up a car on CarGurus.com. I have used this site repeatedly with Firefox but it gave me "Cannot Access Website" error. I am an IT Tech and did a Cache Purge, then a deinstall-reinstall, and finally a Total and Complete Deinstall down to Registry level. No Help!!! Then someone responded on here saying they had the same problem. When I went to check, I was able to connect. Today, Same Thing!!! Chrome works, Firefox does not, so here I am writing again about an Issue I believe is a Firefox Issue. You need to look into this Folks!!!

I am running Windows 11 Pro and Firefox 147. Beginning the second week of Feb, Chase bank will not allow me to log into their system. They say I have to have Windows 10 or higher and Firefox 128. I am running 147. What else can I do?

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

Dear Mozilla,

As a long-time Firefox user and evangelist, it saddens me that the time has come to part ways.

I have seen threads from others commenting on Firefox's aggressive memory consumption and retention. I have not measured this and thus do not feel qualified to comment, but, sadly, I am not surprised.

My own experience in recent times highlights 2 events that have driven me here.

1) Several websites just not responding in that some screens will not even scroll. This is fixed by me moving to a different browser.

2) More seriously - When trying to fill in a web form for a work job application the page was completely unresponsive. When I contacted the web site support their answer was: "Are you using Firefox? Ah, Yes, we are having issues with Firefox that we are trying to resolve. Our suggestion for the time being is, if practical, try using a different browser". That answer worked.

I should add that the usual cache clearing, machine restarts, even Firefox reinstall did nothing to fix either of the above issues.

So with the serious memory greed issues reported by others and my own (dys)functional experiences, I fear the time has come.

Thank you for the last 30 years or so and I am sorry it has come to this.

Best of luck in your future endeavours.
