Firefox 社群討論區

I recently tried to connect to two different meeting sites. Both times I got a pop-up noting (correctly) that camera and microphone are blocked. I'm able to click to enable the microphone but I never get the option to enable the camera.

I tried going to Settings>Security&Privacy>Camera but that only allows me to remove previously-enabled websites.

Clicking on the settings button in the address bar shows audio and recording settings but no camera.

What am I doing wrong?

Fedora 42 Firefox 145.0

They play for a couple of seconds, then the panel they are playing in goes black. They used to work a month or two ago. Videos play fine in YouTube. They also play fine in apps like VideoPlayer and VLC. They play fine in Chromium based browsers Opera, Brave and Vivaldi. My graphics card requires switching acceleration off. I can’t find a switch for that in Firefox.

Problem Videos start playing, then after a few seconds the video panel turns black. Audio may continue. Refreshing does not help.

Environment

   OS: Fedora Linux 43
   Firefox 147.0.1 (also tested Firefox Flatpak)
   Display server: Wayland and X11 (both tested)
   Hardware acceleration: on and off (tested)
   Media Source Extensions: enabled (disabling MSE triggers an “unsupported device” error)

What works

   BBC News videos play correctly in Chromium-based browsers (Brave, Vivaldi)
   Videos play correctly in mpv/VLC
   Other video sites (e.g., YouTube) play correctly in Firefox

What I’ve tried in Firefox

   Disabling hardware acceleration
   Disabling VA-API
   Disabling WebRender
   Disabling RDD sandbox
   Running Firefox under X11
   Using the Firefox Flatpak build

None of these measures help. This suggests the issue is related to Firefox’s interaction with BBC’s player on Linux. Has anyone else seen this, or is there a known workaround?

With normal mice, when you scroll you typically scoll in steps which you feel as the mouse wheel feedback.

The issue here is with high resolution scroll wheels, whether that is a knob or a "frictionless" mouse wheel like on higher end logitech mice.

What happens: You slowly rotate the scroll wheel while nothing is happens in firefox, then you get to a certain point and firefox scolls one step, then you continue to slowly rotate the wheel, and eventually firefox scrolls another step.

What should happen: It continuously scolls as you rotate the wheel. This works in chromium browsers and other chromium based apps like discord, steam, etc, it also works in kde settings app, dolphin, okular, etc. But not firefox. It even works in terminal.

Both firefox and thunderbird are like this.

Is there a way to get this working or is it simply not supported in firefox? If so then feature request: get high res scoll wheels to work

Hi. There is a problem with video playback when skipping through the video using a playback bar. The video (but not audio) freezes at the spot when one skippes to another part of the video and re-establishes after a while (not so short while) to the part of the video that is currently played. I'm using Linux Fedora.

Firefox crashes randomly during video playback. I've submitted over 10 crash reports. Here's the two latest crash report (which includes my device's hardware information): https://crash-stats.mozilla.org/report/index/81eb1750-1dd0-490d-9eb1-d3c2c0250224 https://crash-stats.mozilla.org/report/index/6682a7f2-836a-4365-938e-c9ab20250224

I'm on Fedora 41 + gnome, but this issue persisted even in Windows 11, which caused BSOD therefore I made the switch to linux (At least in linux it doesn't crash the whole system, only firefox). If you need any additional information let me know. I can run journalctl/dmesg if required.

I've already tried things like restarting in safe mode (troubleshoot mode), refreshing firefox etc. Didn't work.

Thanks in advance!

Hello

I use Firefox 132.0.1 under Fedora 14 Linux. Whenever I click an urls in another application (e.g. Libreoffice, Keepass...) a new tab is opened in Firefox (according to Firefox's settings), but Firefox itself does not pop up in the foreground, it remains in the background. I highly appreciate the setting 'open links in tabs instead of new windows'. But FF only comes to foreground in case I deactivate 'open links in tabs instead of new windows'. How can I prevent FF to stay in the background in case 'open links in tabs instead of new windows' is enabled?

Thank you in advance

It says on https://support.mozilla.org/en-US/kb/about-picture-picture-firefox#w_keyboard-shortcuts that the hotkey to toggle `PiP is CTRL Shift ]`. When I play a video it shows the PiP button, but the hotkey doesn't work. The other PiP keys like seeking and volume work. I'm on Fedora 41 with KDE 6.3.3 & Wayland.

Was prompted for various system updates including apps(Firefox). Performance has been very sluggish. At some points, it feels like I'm browsing on dialup. I have a 1GB connection from my ISP.

Not sure if this is a Firefox issue or in conjunction with the other system updates.

Only on firefox, the music on apple music keeps changing volume. I can hear it sound fine for a second but then it changes the volume to around half of what its meant to be. I dont see any settings to change it, its fine on other browsers, im genuinely unsure of what to do.
