There is no audio on any website in Firefox only. I'm using Windows 11

1. Numbered list item When a video is playing there used to be an audio icon showing the tab is playing audio, this does not show anymore.
2. Numbered list item Firefox does not appear in the Windows volume mixer
3. Numbered list item The Firefox Task Manager Utility 'Windows Media Framework Audio Decoder is always idle.
4. Numbered list item I've restarted the Windows AudioSrv service and Windows explorer process

Nothing works. Please help.

Firefox is downloading files directly to my Downloads folder instead of asking despite having turned on every setting that says it should ask first. Under about:preferences I have turned on "Always ask you where to save files" under Downloads, and I have set Applications to "Ask whether to open or save files". I have even gone in to about:config and turned off "browser.download.useDownloadDir", but the files are still going directly to my default folder.

I have multiple monitors and most often have Firefox windows open on each. Lately, I've been noticing that the Desktop Window Manager process is consuming a huge amount of RAM. At the same time, consumption completely disappears with the closing of Firefox windows. Video: https://i.imgur.com/pHCa7Hh.mp4 (I left it for a while then closed Firefox windows) After a while, I noticed that already 13 GB of memory is being used by DWM. I don't know if sites affect behavior, but most often I have https://music.yandex.ru/home open

OS: Windows 11 (Microsoft Windows [Version 10.0.22621.1928]). Firefox: 115.0.1 (64-bit) Screen setup: 1 - 3840 x 2560 with 200% scale, 2 - 1920 x 1080 with 100% scale.

I've noticed this issue happening randomly, some of my toolbar bookmarks listed on the sidebar just up and disappear from view. As if they were never there. But I know they're still saved because when I click to Manage Bookmarks and check them there, they show up fine. The toolbar just randomly hides them for whatever reason, and I can only fix it by closing Firefox and opening it again.

I'm on the current version. I remember accessing about:support and clicking on Verify Integrity while trying troubleshoot some other issue, but don't know if that could've caused it though.

Hi everyone, When i go to the website config.office.com in firefox there is just a white screen. Nothing more. Instantly white. I have checked if this is an issue at the side of Microsoft but it doesn't look like it is. The website does load correctly in Microsoft Edge.

I tried the following in Firefox: - Firefox is up to date (Version 115.0.2 64 Bits) , I have had this issue in other versions of Firefox too. It's not a new issue in this newest version. - Tried disabling all the security features in Firefox, disabling all add-ons, and disabling the extra security for cookies - Starting firefox in safe mode (Shift click on firefox, then open the website) - Checked the Network inspector. All packets have status 200 (See the first screenshot)

You can check the second screenshot for the white page.

Some help is appreciated :) Thanks!

In macOS you can set up a global keyboard shortcut for the Move Window to Right Side of Screen command via System Settings > Keyboard > Keyboard Shortcuts.... In most apps that support the Move Window to... commands, this will simply move the window to the desired side of the screen when the key combo is pressed.

However, in Firefox the key combo will start the animation as normal but the window will then bounce back to its original location. It's only when the command is activated via a keyboard shortcut that it does the bounce back behavior, though; the command works as intended when activated from the Window menu in the menu bar or from Option + green button in the top left of the window.

The key combo I set up was Shift + Option + Command + Right Arrow, but I've also tried a couple of different key combos and they all did the same bounce back behavior. I've tried it on machines with different versions of macOS (Sonoma beta and Ventura) with the same result. The bounce back behavior also effects the Move Window to Left Side of Screen command.

I've been attempting to use FIDO2 w/ PIN support to log into Okta. This occurs with a pre-registered security key (Yubikey 5C NFC on most recent firmware) that has a PIN already configured. This key works on all other browsers and devices without trouble. Firefox is unresponsive to Yubikey interaction after the notice "Touch your security key to continue with <company>.okta.com" and will eventually time out if I do not cancel.

On the other hand, I can register a new security key on Okta through Firefox on this device. When I go through the registration workflow, Firefox is responsive to all interactions, allowing me to enter my PIN and complete registration.

I have been able to replicate this issue on other computers and with a different user / security key.

I've been noticing for the last month that after a few hours in a browser window, I'll suddenly have a pinned tab for some random website. Some for promotional things, others in languages I don't understand, etc. At first I downloaded a webpage blocker, blocked the ones that were pinned, and deleted the tabs. However, after a short while (an hour or two) they would appear again in pinned tabs only this time it would say website blocked.

I uninstalled and reinstalled firefox in hopes that would solve the issue, but it is still happening. I unpin the tabs and delete them immediately after I notice them, but they keep appearing. I really like using Firefox and use it often for work, but I'm concerned for my personal and work security. What should I do?

I've been watching and following along with a Unreal Engine 4 Course on Youtube for some time now (mentioning in case the resource usage has something to do with it), and in the past couple days I've noticed a pretty serious and annoying bug. When I pause the video, tab (Cmd + Tab on MacOS) into Unreal Engine, do some things, then tab back and resume the video, it will play for one frame and then stop and buffer, but the audio will continue playing. The only way to get the video to resume is to skip forward/backward in the video (either with the arrow keys or the progress bar). I've also tried Troubleshooting/Safe mode and the issue still persits.

I download a file. It stops and speaks of a security risk. The website is https, but the file is http. Is there a location I can pre-approve all files from the url to override the objection? Thanks.
