Every time I try to change the resolution of YouTube videos, it only provides 360p as an option, with a "Missing options?" message that redirects me to Google help page that just says my browser might be out of date (I'm on most recent Firefox and Windows 10 updates). The quality is still stuck in 360p when I reboot Firefox in Troubleshooting mode, and there are no quality issues when I use a browser like Edge. What should I be checking to resolve the issue?

The camera won't turn on in the Firefox browser for Google Meet or Zoom. It says it can't find the camera or that it's turned off. I have checked my Windows 11 settings and desktop apps have access to the camera. I have also checked the settings for each of the sites and use of the camera and microphone are allowed. Autoplay is enabled too. The camera works fine in other apps and in other browsers.

I'm trying to sync my tab groups across my desktop/laptop. I have sync enabled through the settings and I've checked every box, but I don't seem to see an option for syncing tab groups specifically. It syncs all of my bookmarks and active tabs, but the groups seem to be unique to each device. Is this feature available? I might be looking in the wrong spot so if anyone has any insight that would be great! Cheers

Hello, I'm having a problem on Windows 10. It's a fresh windows installation and I tried already some solutions: reinstalling firefox, deleting cache, refreshing firefox, private windows, no add ons, trouble shoot mod. Nothing helped. The problem seems to be with live stream, either on twitch.tv or youtube.

When I open any stream, it takes about 2.5 seconds from the start of the page loading to the appearance of the stream image and playback. For comparison, in version 137 it took about 1.0 seconds.

I tried to launch the browser (Firefox 138.0.1) in troubleshooting mode, and also created a new profile, but the problem remained.

I also downloaded portable versions: 137.0.1 - everything is fine. 138.0 and 140.0a1 - slow loading.

I also have Zen Browser installed (the latest version is based on 138.0.1) - everything is fine.

Why does the Bilibili website not display the corresponding screen when I try to move to it? Speed playback cannot be used at all, and there’s also the issue of not being able to use fullscreen on Firefox. Are you forcing me to use another browser?

Hi,

I have a Mac with Sonoma. Somehow a while ago I ended up with Firefox ESR, which I was told that will not be supported after September.

I am a non-technical user. While I do have Safari and Chrome, I would prefer to continue using Firefox.

Could you please let me know the steps to execute to somehow switch from the ESR version to the current normal version without loosing settings, bookmarks or ending up with problems? Thanks in advance.
