I have been receiving the following error code 'PR_END_OF_FILE_ERROR' on several website on my Firefox browser. Sometime, not all the time, I get the same error message while trying to use YouTube, while other times the site loads but says that I am offline and no internet connection. I have done all of the fixes that they say to use online and nothing seems to work. YouTube will occasionally work but none of the thumbnails will show up. Then there are other site that work fine.

Hello,

we have a BigBlueButton Server setup for our company. Until recently we used a TURN-Server to tunnel the UDP connections thrugh the firewall.

Due to performance issues we wanted to try and let the clients connect directly to the udp ports 16000 - 32000

In Chrome this works as expected.

In Firefox however when we set "media.peerconnection.turn.disable" to "true" FF does not find any WebRTC candidates. We checked the logs and it says there:

"relay only option is set without any TURN server configured" "relay/proxy only option results in ICE TCP being disabled"

But thats NOT true! The option "media.peerconnection.ice.relay_only" is definetly set to "false"

Tested on FF 115.5.0 ESR and 120.0.1

Does anyone have an idea whats happening here? Why doesnt FF even try to make a direct connection?

UPDATE: I just ran a test on our dev system. If we configure BBB so that it does not offer any TURN-servers, FF uses a direct connection. Sadly that is not possible, since we need the TURN server for external connections. When there are TURN-Candidates but TURN is disabled via FF config no connection is established at all. This definetly semms like a bug in FF, since the browser should still be able to simply try and connect directly.

Dear Community,

Been having a problem with downloading for about 2 weeks now.

I am doing a course in Ethical Hacking, and have been told to download an .ova file from the internet. The download is 8.5 GB.

However, it has failed on, now, 8 occasions. The nearest it has come, is it has downloaded 5.1 GB.

Could anybody recommend another tool to download files better and quicker? This course is now almost halfway through and I still have not managed to download the software. Any suggestions would be most welcome. Could it possibly be the case that my anti-virus, Microsoft Defender, is not letting the download through? If so, how could I switch the anti-virus off, please?

Within the last week or so, a certain website (libsyn.com) that serves Podcast audio has been doing something strange to their content that causes Firefox difficulty when playing back in-browser. If I try to jog/skip through the audio, certain portions will cause the time to continue advancing, but Firefox will not play any audio back. Here's a sample. Note that if you allow the full URL to be loaded, then load the stream into VLC, VLC is able to play the audio just fine without any issues.

Hello,

I've read and tried the fixes to open the newly updated (deleted and installed 3 times) Mozilla Firefox and nothing is working. I've pressed down alt to open in safe mode and I am unable to get it to open. I've looked for the Facebook plugin to disable it (saw a comment on that) and the plugin folder is empty. Is there a help desk with an actual person that can figure this out?? It is quite alarming to see so many other people with this problem and no real help from Mozilla employees themselves. HELP!!

My regular profile has deleted all saved history, tabs, bookmarks, etc. This happened before and seems related to having private browings open. and to an update in progress or recent.

Opend a private window. Then noticed regular FF wasn't opened. I opened the usual profile and all saved info is gone. Also, my stuff to be synced is way out of date so can't restore from there (I always had sync up to date). My "backup" can't be opened to restore.

Where do I find yesrterday's info? How do I restore my session, bookmarks, etc?

Last time, I tried to follow directions I found soemwhere but the instruction werent clear at all and had to restore from a disk image.

Why is there stsill the private window deleting regular window?

LibreWolf provides a better service maybe you could understand the frustration that Firefox had on me. There's no section for videos.

I often drag elements on trello.com. Whenever I drag an element, that element seems to double in size, making it hard to see what is underneath. Attached is an example.

I believe this is related to the fact that I am running Linux/X11 and my DPR is 2. From about:support:

  • Window Device Pixel Ratios 2,2,2,2
  • Window Protocol x11
  • OS Linux 6.1.0-13-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.55-1 (2023-09-29)

Is there an about:config setting or anything that will prevent scaling dragged elements?

This problem just started recently, where I can't unmount an external USB drive without getting this error message:

The disk "Projects" couldn't be ejected because "Firefox" is using it.

I hate to keep quitting FF just to unmount a USB drive - that means logging in again to various web accounts.

My only extensions running right now are Enhancer for YouTube, Grammarly, and Facebook Container.

What's preventing me from unmounting a USB drive?

Greetings from Greece,

i use Mozilla Fieefox many years now to sync everything from home, to mobile and work. Today at work, I received a new computer with fresh Windows 11 installation, bind to an MS Domain and the latest version of Firefox installed.

With a great dissapointment i realised that i couldn't connect with my mozilla account while in the previous pc with with windows 10, worked and synced flawlesly. While pressing "Sign In" from the 3-line menu on the top right corner nothing happens, sometimes it opens a window that keeps loading and some times the login page is loaded. After inserting the email and pressing the button it takes quite some time, a red ribbon notification appears "Proccessing..." and when next screen appears and the password is entered... (it takes also quite some time) the red ribbon notification appears "Working..." and after a little while "The operation was aborted".

I've uninstalled and reinstalled firefox, cleared profiles and created new ones, took advantage of all refresh tools mozilla offers.... nothing. In fact in all 3 pc's we received today the reaction was identical. On the other hand if i try to login to mozilla throught Chrome or Edge the login process works like a charm.

Any thoughts, ideas would be very much appreciated.. could it be a Policy Problem for Windows 11 for example?!?

Thanks in advance for your time
