Hi rawrifficus, When you click on the padlock icon at the left end of the address bar, you can change the permission(s) for that site. This will create an exception in your Options -> Permissions. When you want to change it back, click on the icon on the address bar or remove the exception.

Here's an article: How to manage your camera and microphone permissions with Firefox

which can help with other questions, too.

Oh I apologize I wasn't clear in my request. I was wondering if it's possible to remove them while still having the microphone active?

I found this answer in another question -

There is no built-in way to remove that icon.

You can use a custom style rule in a userChrome.css file to hide it or to make it more transparent. I haven't experimented with this myself, but here are a couple resources if you want to give it a try:

• https://www.reddit.com/r/firefox/comments/78pjz1/how_do_i_remove_this_microphone_indicator/
• https://www.userchrome.org/how-create-userchrome-css.html

I hope it helps.
