Firefox Support Forum

In the last week or so, iPlayer, All4, and Spotify (that I know of) have stopped working in the Firefox browser. All4's error suggests DRM isn't enabled, the others just say try again. Roll20 hasn't been working for even longer (more like months). They work in Microsoft Edge and Chrome. Youtube is still working, as are video players in social media.

I have tried the following solutions:

• Firefox is up to date
• Windows is up to date
• Updated graphics drivers
• 'Widevine Content Decryption Module provided by Google Inc.' is set to 'Always Activated' and is up to date
• 'Play DRM-controlled' content is ticked in about:preferences
• Checked if anything changed if either of the above were turned off (it did not)
• media.eme.enabled is set to true in about:config
• Put Firefox in troubleshooting mode
• Turned off my addons (including uBlock Origin) manually
• Tried in a Private Browsing window
• Turned off Tracking Protection
• Restarted my laptop

Nothing has fixed the problem, or given me any more indication of what is wrong. I don't know how to a) fix or b) find the problem. All I can think is that it may be related to the recent changes to Chromium regarding ad-blockers? But no one else seems to be having the same problem so I doubt it.

I'm using a new PC with Windows 11 and find that I, inadvertently close Firefox with 16-20 open tabs. Most of the time when I reopen FF, the tabs are still there, as expected. Sometimes, the browser opens with just a new home page and the pinned and other tabs have closed. I can sometimes see the 16ish tabs in history and reopen them. More recently, I find that they are not in history as a number of tabs so I have to set them up again. This rarely happened on my old PC and if it did I would have bookmarked a group of open tabs that I used regularly.

The failsafe FF General setting is as follows: Startup, Open previous windows and tabs.

I don't know how I can stop losing my open Tabs but if I was able to bookmark all the open tabs to be used in case of a problem I would feel more secure.

How do I bookmark ALL or several my open tabs?

After the most recent update, Firefox often takes 30 seconds or longer to load pages. This behavior began yesterday and has continued today. This isn't the first time this has happened. Solutions?

I need a fix for my ESPN+ account. I can watch live sports and videos but cannot read ESPN+ articles. Everything works great with Edge and Chrome, so maybe I will have to switch browsers.

Hello, the description is the same as in the title: Firefox is slowing down significantly while I have "more" demanding games running I'm talking about a game like assassin's creed mirage mostly on ultra for example.

It all started with the purchase of a new computer, on the previous one I did not encounter such a problem. It manifests itself in the way that the video is slightly desynchronized with the sound + I can see a significant difference (delay) when scrolling the pages.

My current rig: Intel Core i7-14700KF Nvidia RTX 4080 32GB of ram running at 6000mhz (G Skill Intl F5-7200J3445G162x16GB ) 2x Kingston SKC3000D2048G 2TB

I understand that the GPU focuses on the game but can't it be improved somehow? The rest of the applications on the computer work normally In my opinion, the computer does not seem so weak that it cannot handle Firefox and the game simultaneously.

Send help please 😊

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

Hi,

I am a student, who tend to mass download files at once. The annoying part is that after every download, firefox automatically opens up the downloaded file in a new tap. How can I disable automatically open files after download?

Thanks.

My ISP had provided the IPv6 service, edge/chrome/vivaldi are all IPv6 first and working well. Only firefox insists use IPv4, although it could also pass the IPv6 test on https://test-ipv6.com, and the internal test on https://detectportal.firefox.com/success.txt?ipv6 It leads to some webpage extremely slow, even could not be accessed.

I've tried privacy mode, but the problem is still there. IPv6 in about:config is enabled, all related options are default. Is this a bug, or if there is any way could fix it by some special settings?

Waiting for your help, thanks.

I have noticed a bug with how the Firefox icon appears when launched in the Windows 11 taskbar when the never group option is enabled. When Firefox is launched and is the only application open in the taskbar, there is no label present next to the icon like other programs have when launched. There is the little line underneath the icon though indicating it is launched but that is it. As soon as I open another application though, the label will also appear for Firefox. This is only a minor annoyance but is definitely as bug at least for me and should be pretty easy to fix. I will attach screenshots of the behavior. In the first screenshot, you can see that Firefox is open but has no Text label like it is supposed to. The second screenshot is as soon as I open a second application.

I am on Windows 11 Home 23H2 Build 22631.2792 Windows Feature Experience Pack 1000.22681.1000.0 Firefox Version: 120.0.1

I cannot get screen share, webcam share, microphone share to work with my default profile. I get a Cross Origin Request Blocked. If I create a new profile everything works as it should even if I install all the same plugins. I have tried changing security..cross_origin in about:config and it makes no difference.

I have a lot of tab groups and sorting in my default profile, so I'd prefer not to have to set that up in a new profile. Importing to a new profile ends me up with the same issue as above.

This error is profile specific and I am wondering if anyone knows the specific profile files that I could regenerate, delete or replace to tackle this cross origin blocking.

Also I've disabled all my plugins, and enhanced tracking protection on the default profile and it still does not work..

Thanks.

Everytime I go to play games on my laptop I close Firefox for the extra resources and when I'm done I open it right back up, I have done this for YEARS but this time it didn't restore my session. I thought it would be as easy as the last time where I'd go click the Restore Session button but it isn't there so I spend two hours looking for solutions and found nothing. I don't know how this happened nor do I understand how this could happen in the first place, my Firefox hasn't crashed in months and I had already closed and re-opened it several time today.

Hello everyone. Since installing Linux Mint in May 2023 I have been having this issue with Firefox.

Description of issue: When I switch between (or drag) tabs in a Firefox window, the whole window becomes unresponsive, with the last tab I was switching from still in front. Often the contents of the window start to flash (disappear and reappear, leaving a black backgground) every 2 seconds. I can drag the window around, scroll, minimize it, but it is impossible to give any input in any tab. The only action somewhat possible to do inside the window is bring other tabs in front, it is still quite hard for the input to register, and if it does, it takes 10+ seconds. The issue goes away if I close the specific Firefox window, or if I manage to select and drag one tab out of the frozen window into its own new window. Then everything works as intended, like nothing ever happened.

I can reliably cause the freeze-up in a short time by holding CTRL+TAB and drag one tab to change the order while firefox cycles through the tabs in the open window.

While the window is frozen, the rest of the desktop is responsive as normal, even other Firefox windows. If I try to interact with the frozen window I can rarely see spikes of CPU usage. RAM stays at normal usage levels, far from being full.

What I have tried so far that has had no effect on the appearance of the issue:

1) Disabling all extensions i have

2) Run in troubleshooting mode

2) "Create a new places database" as suggested [https://support.mozilla.org/en-US/kb/firefox-hangs-or-not-responding#w_fi...]

3) Disabled hardware acceleration

4) Creaing a new firefox user profile

5) Use "Refresh Firefox" from the troubleshooting page

6) Use the Flatpak version of firefox

7) Reinstall firefox

Here is my system information

For some reason Montserrat fonts ignore font-weight for me on all websites. In happens on my main browser profile, with a new clean one with no add-ons and even in Tor Browser. Pictures 1 and 2 illustrate the problem. If i go into page inspector and replace "font-family: 'Montserrat', sans-serif;" with "font-family: 'Segoe UI';" the parameter works as expected and the alternative font is rendered properly.

Reinstalling fonts from fontsource.org didn't help.

OS: Windows 10 1607, FF - 120.0, issue was present for many versions before.

I have a new PC running Kubuntu 22.04, with Mozilla Firefox 120.0.1 (64 bit) installed. Standard, the system window title bar was hidden. But I wanted access to the "Move to desktop" menu and wanted the title in the title bar. So, in "Customize toolbar" I checked "Title bar". The title bar reappeared, but a complete border along the Firefox window became inaccessible, and when clicking in that zone, it effectively clicked in the window behind. In particular, the complete menu bar is inaccessible, as well as the scroll bar on the left and in the bookmarks sidebar the fold/unfold. And Mozilla Thunderbird 115.5.0 has the same annoying behaviour. Even when hovering over some menus in the Mozilla window, you can sometimes see reactions from the window under the Mozilla window. On older Kubuntu computers (up to 18.04) with older versions of Firefox (up to 113.0.2) and Thunderbird (up to 102.11.0) I do not have that problem. How can I get at the same time access to both the system title bar and the menu bar ?

I've spent many hours trying to fix this problem. When I click on a document that I want to view, it is downloading to my computer. I have the latest version of firefox on a windows 11 pc. Please assist.

Update to Firefox (120.0.1) in Linux Mint blocks CNN - its the only site which appears to be blocked. I get a message telling me that configuration of the site is blocking CNN from loading, and goes on as follows.

"" We apologize, but your web browser is configured in such a way that it is preventing this site from implementing required components that protect your privacy and allow you to view and change your privacy settings. This functionality is required for privacy legislation in your region.

We recommend you use a different browser or disable the “EasyList Cookie” filter from your “Content Filtering” settings (found under “Settings” -> “Shields” in the Brave Browser). ""

Rather strange, since I'm using Firefox.

In general, I am thoroughly annoyed with the way the Internet experience is increasingly fouled up by various sites implementing "safety" aspects. It used to be fun, now its a crap experience. Firefox is getting bigger, slower, and infested with site 'improvements' which do absolutely nothing for me - Is it so hard to provide a simple, clean, straightforward browser without so many 'add-ons' that its grinding to a halt? Time was software was written for the users, now its clearly written to give software developers something to do. Can't you create a revolution in software and do something useful, instead of "clever"?

Firefox just updated to version 120.0 I hadn't used youtube for a while. When I tried to play youtube videos none of them will play, only get a green screen with audio In troubleshooting mode they will play Refreshing firefox does not fix the problem

Is there a setting or add-on for firefox (Windows) that will block tracking pixels? My email client hi-lites when present and as I understand they are incorporated within images so I dont down load attached images to reduce them. On their pro version they allow blocking of these pixels. Unlike cookies there doesn't seem to be an option on reception to opt out. I'm not fully clear what harm they do or whether they are session use only and delete on power off. I would rather not recieve them atall. Companies when challenged smokescreen and refer to cookies rather than pixels or bang on about their companys integrity.

Thanks for your help
