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?

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?

Dans free.tv pourquoi la suppression des sous-titres ne fonctionne pas problème Mozilla ou Free.tv ?

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.

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.

For the past two days I haven't been able to get past the recaptcha on several sites (Facebook, Instagram). I have tried all the workarounds other users have provided and what Google has offerd to no avail. I'm also having a difficult time accessing my hotmail acct from Firefox as well. I don't seem to have this issue with either of these problems if I move to a different browser. Firefox has always been my main (and only) browser, yet more and more often I seem to have issues anymore. What the F is going on? Would appreciate any help I can get. Again, I've tried removing Ad Blockers from these sites and even turned off the 'Enhanced Tracking' thing on the address bar; none of this works.

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?

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.

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.

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!

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?

Firefox has been laggy at times lately on my PC (Windows 11 Home, Firefox 152). I have tried some fixes with no success (clearing the cache, deleting YouTube cookies, using the User-Agent Switcher, etc.) Other browsers appear to be unaffected. I first noticed this on YouTube, but it seems that other websites are affected as well.

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.

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.

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
