I recently started to have a printing problem in Firefox on Windows 11. My Brother DCP-T720DW works fine with other applications like Word and Notepad, but when I try to print from Firefox, sometimes I get a "Printer not available" message or the print dialog incorrectly shows the printer. For troubleshooting, I uninstalled and then reinstalled the printer driver following the official Brother download page: https://support.brother.com/g/b/downloadtop.aspx?c=us_ot&lang=en&prod=dcpt720dw_all Since that didn't fix the issue, I also downloaded and reinstalled the driver from: https://printerdrivers.com/brother-dcp-t720dw-driver/ Windows detects the printer and is able to print test pages, so it looks like the problem is only with Firefox. Here are the things I have tried: Restarting both Firefox and Windows Uninstalling and reinstalling the printer Resetting Firefox settings Running Firefox in Troubleshoot Mode Making Brother printer the default one

Has anyone else had the same issue in which Firefox refuses to detect a printer that works correctly in other applications? Is there a print setting or preference in Firefox that might cause this? Thanks in advance for any advice.

Following a recent update of my bios (AMD Ryzen) of my PC the on-board sound system failed. I chased down the issue, got a sound card to circumvent the on-board circuits, and had sound once again but for my FireFox (Ver 133.0.3, on Windows 11 Home, Ver 10.0.22631 Build 22631). Testing with alternate browsers (Edge, Opera) the sound works, as do my downloaded games and music but no joy with FireFox.

My question: Is this a known issue being addressed for a future update or are my circumstances an outlier issue?

On May 1st, when I launched Firefox(afternoon some time on US East coast) it ran an update to 138.0.1. When it was done, it did not launch. So I clicked the icon on my desktop and it came up, but then closed out after about 15 seconds. When I reopened it, it asked to continue in troubleshooting mode or refresh. I tried both. No luck. I restarted and even uninstall and reinstalled the latest version as well as tried installing 137.

I have tried with virus/malware protection/firewall off. I have restarted. My page file is default. I tried renaming the firefox.exe to something else. I tried creating an new firefox profile(firefox.exe -p) but that crashes too.

I installed the latest version of Firefox Nightly and it stays open just fine. But when I launch the regular firefox, they both close.

I also installed the Firefox app from the Windows store and it behaves the same as the one from the mozilla website.

Evil Corp (aka Microsoft) updated my Windows 11 PC from 24H2 to 25H2 and now I cannot access quite a few websites (i.e. Amazon, Bank!, etc.) and some take a long time to load (surprisingly, my Firefox Home page...Google...also takes a while to load) . I searched the internet and found many so called fixes and most are very complicated and many contradict others. A lot of them say to disable DNS and reset network stack (using the command prompt) which I do not know how to do even though I worked in the tech business for 40 yrs (mainly data networking)...I retired 20 yrs ago...so I'm old...so I'm not as savvy with computers as I used to be. I tried changing a few Firefox settings, but nothing worked, so I changed them back to the original settings that worked before the update. If someone could give me detailed (and hopefully simple) instructions to resolve this issue, I would greatly appreciate it. I'm am in a bind, so a timely response would be great. Thanks so much, Steve

I have a problem using a website called TherapyNotes with the Firefox browser, even though this was not an issue until recently. It seems even though camera permissions are enabled, Firefox is unable to connect to my camera for my telehealth sessions. The light indicating my camera is in use comes on for a second, then immediately turns off. I am also unable to even start a session and coast with voice only. The window to start my session never pops up. I have put in a ticket and been in contact with TherapyNotes going back and forth for the past couple of weeks. Their tech support insists it is an issue with Firefox since I can utilize their site completely on other browsers. I much prefer to use Firefox for the security, so I'm hoping there's something you can tell me to do to make it work.

Using Firefox on Windows 11 I cannot access DocuSign files. I need to send a form to an on-line bank and want to use the DocuSign function. When I click on that option on the site all that displays on the screen is DOCUSIGN but the feature doesn't show. I tried turning off security addons such as Privacy Badger and Ghostery but that didn't help. I can get to the feature using Edge but I really don't like using that. Is there a setting that I've missed that may cause the disconnect?

The generic DocuSign site it https://powerforms.docusign.net/. Any other details in the URL I used refer to my bank and the account, so I am not including that information.

Thank you.

cannot open allmusic.com website anymore on firefox. this website opens fine on other browsers. Only Firefox is the problem. Any suggestions?

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.

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:

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.

I am trying hard to keep with Firefox and trying to avoid being sucked into Google Chrome. However am finding increasing problems with Firefox. I am am sure I have the latest Firefox download but not able to download my Barclaycard statements. I can see my recent transactions so have access to the Barclaycard website but cant download my statements which I can do on Google Chrome and was able to do on Firefox up until this month!

The only odd thing is in the past I have had to authorise via the app which it tells me to use but doesn't ask me to actually do it and goes straight into my account.

Barclaycard say the problem is with Firefox and they are not in anyway restricting access via Firefox.

Thoughts? Ian

Firefox is misdirecting me to a Microsoft Sales page instead of taking me to Outlook. This issue began several weeks ago and is ONLY happening on Firefox. Chrome, Brave and other browsers work correctly. I'm using Windows 11 and Firefox's latest versios.

Here is a short video showing the issue. https://app.screencast.com/QpeMzzoytwq99

Hi, when I want to zoom in to the website page, I cant seem to find the horizontal scroll, thus I cant see the left side of the page that I zoomed in. Please make the horizontal scroll available. Thank you.

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 ...

I have a new desktop i7 computer with 16 GB of RAM. Why are my Firefox browser screens locking up? I'm running Windows 11 Pro. I don't have this problem with Chrome.

'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.

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.

Hello, I think I may have asked about this in the past but cannot recall if I received an answer. Under Settings, I get the message "Your browser is being managed by your organization." This is my home computer and is not being managed by any organization. When I click for more information, it gives me a screen with the following information:

Policy Name Certificates

Policy Value ImportEnterpriseRoots

                         true

If I could get more information on this suspected error, or how to correct it, that would be great. Thanks!

Using Windows 11 just reloaded on new hard drive (Solid State). Old hard drive took up smoking. This error does not happen on any other site and did not happen before.
