Did you check your mic settings? see screenshot

my mic settings have never changed. its always worked without changing any settings. its not a mic issue bc if i go to google chrome or any other browser ppl can hear me fine using the studio display monitor audio

Post a screenshot like mine showing your setting in GM. You can see from my test that voice works. see screenshot

if i clap the blue audio bar doesnt move when i make noise, but works fine on google chrome. its a firefox issue.

What OS? Verify what Firefox is using for the mic. You can also test here. -->https://mictests.com/

macOs sonoma 14.6.1 (if i go into google chrome, which is also using the studio display microphone, it can hear me. but when i go into firefox and have that same microphone chosen, its not picking me up any more, but it used to work a few short weeks ago and nothing has changed besides firefox upgrades). Firefox 130.0 (64-bit)

more proof that firefox isnt picking up the microphone for some reason. makes no sense. it worked for months, then stopped working and i filed a bunch of reports and they fixed it on their end, and now its back to not working again.

On the site, click ctrl+I to get the screenshot and check permissions.

On google meet.

As a test, you can install an older version in a different directory and see if it works. Make sure to go into the setting and change the setting so that it doesn't auto update.

I'm not willing to mess with figuring out what directory to install it to, and going into settings to try and figure out how to fix auto update. too much margin for error. I'd like Firefox to issue a browser update to fix this.

Understand. Did you post a screenshot showing Google Meet settings? Did you try Firefox in Troubleshoot Mode? Maybe someone here has similar hardware to also test. If not, you can open a bug to see what devs can find.
