Windows 11 Pro - Dell XPS8940 desktop - i9

Firefox will not play video from a website. If I save the video, it is a MP4 file. Windows Media Player and VLC will play the video file. But the browser shows the message: "No video with supported format and MIME type found."

Chrome and Edge will play this video correctly in their browsers. Firefox will not play the video on 3 different computers, and even when a different user account is involved (without Firefox sync).

The evidence seems to point at firefox. The website is a Wordpress site.

Is it possible that the website is the problem? If so, why do Edge and Chrome work?

I uninstalled Firefox (latest version) and reinstalled it. Not fixed.

My windows updates are current, as are Dell updates.

This is stumping me. I hope someone can help.

Hello

For a while I have been selecting wall street journal articles and then clicking "listen".

A few weeks ago this stopped working on one computer a fairly new Lenovo running Windows 11. Currently running firefox 133.0.3. When I click "listen" on any article, nothing happens. Clicking "listen" on another Windows-11 computer on the same article does work, so apparently something is wrong with the settings on this one computer. Any suggestions please?

thanks

Ben

I've used Firefox for many years. The past month or so weather radar doesn't come up on multiple weather sites, pages are slow to load or don't load, getting error codes on video's, pictures don't always load, and many other problems. I uninstalled Firefox and re-installed the current browser and I still have all these problems. I'm having to use another browser now. I run Windows 11 on my PC.

For the past few weeks Firefox has been crashing and freezing often. Crashes are worst when trying to access Protonmail, which almost always crashes the tab instantly. Freezes happen most often when browsing Reddit, and also when watching Youtube, but crashes and freezes can happen on almost any website.

I have tried changing profiles, refreshing and uninstalling/reinstalling, but the problem persists and seems to be getting worse over time.

Here are some recent crash reports:

Will be grateful if someone can help me get to the bottom of this Thanks

Hey all, I'm hoping someone can help me. I have found no answers online to date.

I cannot print from the Firefox browser. When I click the print button, my printer spits out a blank page.

I can print from any other browser, Word, Excel, PDF files, anything except for Firefox. This may not be as much of an issue if Firefox wasn't my primary browser, so when I start doing work on it and find I need to print something at the end, it's a problem.

My printer software is up-to-date, I tried resetting the printing preference to default (assuming I did this correctly), and I even uninstalled and re-installed Firefox (which was a disaster). None of this helped.

Is there one of you who may be able to provide me with the help I need?

I appreciate your effort greatly.

Hello! I started encountering this problem as I updated my OS to windows 11. I had eset nod antivirus, but uninstalling it nothing changed. Tried to change MTU cache size through CMD. Changed different DNSes Tried to disable all protection settings in browser and in windows settings. Deleted all extensions. NOTHING helped except clearing cache of the browser, but this is fixing problem only before first browser restart. Other browser on laptop works normally without any issues.

As I was downloading a video from Google Photos, it showed the yellow by the download arrow and said it failed. I tried multiple file types: mpeg, jpeg, mp4, exe. I googled what to do and my answer was: Disable extensions, start in safe mode, clear cookies, clear history, clear download history. I did all that and I can still not download. I restarted my computer and nothing changed. on FF version 136.0.2

Firefox is no longer compatible with my bank's system. I can't log in with the secure access code the bank sends to verify my identity when using Firefox. The bank says it is a problem with Firefox. Other browsers work flawlessly ... are you working on a solution? I only use Firefox unless forced to use something else ...

Hello. For a while now I have been using the picture-in-picture feature to play a video in the corner while using other applications. It has been a great help as I have a single monitor.

Unfortunately, I have recently been encountering a severe issue with the feature over the last week. When attempting to use picture-in-picture while my computer is running a videogame (through Steam) my entire system will freeze. The audio still plays as normal, but the image is frozen and the system is unresponsive until I force a shutdown and reboot.

Any help at all in with this issue would be greatly appreciated, thank you.

I am trying to install firefox on my new work laptop. The OS is Windows 11 Pro. It came with an ARM CPU. Specifically: Snapdragon(R) X Elite - X1E80100 - Qualcomm(R) Oryon(TM) CPU. Everytime I try and install Firefox, which is probably over 10 tries by now, it fails with generic errors. I have tried cleaning everything Firefox related off the PC before subsequent attempts and still get the same errors. I am including a screenshot of what I see shortly after starting the install process.

Sat. 04/19/2025 @9:10 am CDT - Hi. About 2 months ago on any Settings page, FF began to show "your browser is being managed by your organization." The problem is - it's a STANDALONE box, not connected to any network beyond my ISP. I do own websites but I'm not perpetually logged into the host company, so their switch to Microsoft Entra wouldn't have an effect, I would think.

What settings do I change to make FF know that I'm not on a network? Thanks in advance.

My Firefox Browser keeps crashing at random times. I was using Chrome previously and it was worse than the Firefox performance. I just installed 128 GB of brand new DDR5 RAM which I tested in windows with no error. I have no malware on my computer currently. I ran all of the usual checks that you suggested with regard to extensions and cache. Here is the most recent report ID that was generated by Firefox:

bp-7c5d5dcf-2fc9-40a3-9659-ff55f0250424

Since the last update (136.0.4 (64bit)) firefox only partially shows an embedded google spreadsheet. It was fine in the previous version. Tried turning off enhanced tracking protection, but that didn't do anything.

Good day

Firefox was working fine till yesterday. No changes of any kind were made.

Firefox will no longer play any audio.

Audio plays just fine from every other browser and Windows test.

I have attempted and followed many variations of suggestions and still no sound. Been through permissions.

Any one have a silver bullet to get audio back?

Thanks

I have a Dropbox Paper document that I use for my bookmarks. It lists the name of the site (with link attached) and hints as to my username/password for any given site I use.

For years, it has worked just fine, but trying to solve a different problem, something happened (in my settings?) that renders those hyperlinks non-working. When I click on, say Facebook, it formerly took me right to FB. NOW it gives me a weird yellow box in the upper right corner that says "about:blank" in the upper left of the box, and 3 white boxes at the lower right of the yellow box "Allow" "Deny" "Close." If I click on "Allow," I get a blank page. My navigation doesn't seem to recognize the links I've placed in the Doc.

A friend on FB posted a link to a YouTube video and when I clicked on that, I got the yellow box with the proper URL and a white box option to continue. I've tried to recreate that particular box, but, apparently, once it's accepted, it's OK from there on out.

I have tried deleting the link from the Paper Doc and reinstating it, and I still get the yellow box.

What have I done and how the heck do I get rid of that yellow box?

Having issues with my Bluetooth AirPods and sound in Firefox. The problem being there is no sound when the device is connected and watching a YouTube video for instance. Things went wonky after the recent update to 133.0.3. At first there was no sound period. Then somehow, not even sure how, I saw that Firefox was muted in Windows (11 Pro) settings. That's a mystery unto itself since I'd never previously gone to that area. Now that I have volume through external speakers working, audio through AirPods doesn't. Everything works fine using Edge and audio from music. I know the device is connected and when that is, it's the default for where sound comes from. Used the test thing and yup there is audio. Is there something I'm missing? There must be but I can't figure out what it is. Hopefully someone reading this can point me in the right direction of resolving this issue. Thank you in advance.

'Running ver 137 and now cannot print to my system default printer. Tried the Troubleshoot fix and same result - defaults to PDF. Is there any entry in about:config to ensure system printer is selected. I have checked all system settings and brother printer is the default.
