@burnout426 said in Why is the red circle flashing on the tab?:
If you did not give permission for recording (via microphone and or camera), maybe some extension did it. At the URL opera://extensions, you can disable your extensions one by one (testing after disabling each) to see if one is causing it.
Yes it's true. Yesterday I checked one extension for sound in the browser, when you turn it on, this circle appears. thanks for the help
