Firefox Support Forum

I normally have multiple FF windows open on multiple desktops. After a restart all of a sudden every time I create a new desktop, FF duplicates browser. If I open a new FF Window it will automatically appear across all open desktops.

Tried pretty much everything: Multiple restarts Cleared Cache Refresh Firefox General Settings changes

FF 119.01 Monterey 12.6.6

Any thoughts appreciated

Hello, I cannot get videos to go into full screen in FF as they used to before latest update. Tested on various sites. There are no controls shown on YouTube unless i either hide the taskbar or scroll down both of which is a nuisance. On some sites the task bar stays at the bottom which it didn't used to do. link text

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.

Thank you for you support

Dear Sir/Madam:

I am using Firefox Browser 102.15.1esr (64-bit) on a MacBook Pro Ventura 13.5.2.

I have been using the www.dictionary.com website for a long time, but recently when I attempt to go there, I keep getting the error message as follows:

Unexpected Application Error! FM.findLast is not a function

I tried clearing caches under Privacy & Security, but the problem persists.

(Meanwhile, I can visit www.dictionary.com on Safari and Google Chrome.)

Could you please let me know what is going on?

Thank you,

Roland

Greetings, I am a 77 year old geezer and I have been using Firefox for probably 25 or 30 years. PROBLEMS: 1) bulk emails sent to my customers are rejected by mostly gmail accounts. 2) Emails sent to me of airline group bookings arrive as pages of code that I cannot read. THESE TWO ISSUES ARE NEW PROBLEMS I HAVE NEVER SEEN BEFORE -- STARTED ABOUT 3 MONTHS AGO 3) How do I move/transfer all of my address books/database to a gmail account?

Like I mentioned, I am a geezer, so please be gentle as I understand none of this. Thanks, Walt

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?

Hello

I have a problem with signing in to my youtube account('s) it tells me that i dont have access anymore.

I tried some fixes like clearing cache, history, proxy and other things you can try. But it still doesnt work

account is fine i can login on other browsers but i think firefox is the best one out there so used to it.

anyone know a fix that might help?

Kind regards Collin

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?

Thanks!

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!!

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.

On the Facebook desktop, the Firefox push notifications keep switching to off. I cannot see these notifications as a result, as you can see from the image where the information is blank. I have tried everything possible to fix this issue, but it remains. Any help in fixing this issue would be appreciated.

I installed Firefox on a new laptop and synced it. The bookmarks all were transfered. But when I log into some websites they do not recognize the password, even when the passwords are correct and still work on my previous computer/Firefox brow’ for ‘Firefox.

Dear Mozilla

I'm participating in a discussion group based on Wordpress (learning.martinus.dk), and when I try to sign in (learning.martinus.dk/wp-login.php), I get the error.

>> 406 Security Incident Detected Your request was blocked. The public IP address assigned to you, by your internet provider, might be suffering from poor reputation: Look up IP reputation here. <<

My IP adr. is 80.208.65.123 and it is NOT suffering from poor reputation -- and no problem when I sign in from e.g. Chrome!

So what can I do so I can use my favorite browser here too!?  ;o)

All the best, Henrik Denmark

I remember having: Panaroma, 2 tab organization and several YouTube addons to enhance my experience like Adblock, unhook, dislike return. And with several tabs as checkpoints for my search but I couldn't separate them and also it lagged a lot when having unloaded tabs. LibreWolf provides a better service maybe you could understand the frustration that Firefox had on me. There's no section for videos.

Dear firefox team, recently I use firefox on my windows 10 pro and when I use to open YouTube. Com it opens but when I play a video it starts buffing after one time of refreshing it plays and it is same at all time so please fix it

The problem comes up for two days after Windows crashes with a blue screen. After POR Windows recovers itself and now works, but FireFox and Thunderbird chrashes immediately after start. Do you have an idea, what can I do? FireFox crash ID: bp-c4fe47cd-45dc-4024-8cc1-4a2220231204
