Rated 5 out of 5 stars

Very cool. I created a screen recording addon, not yet released due to issues with upload. But it shows this rtc indicator. This allows us to turn it off. I'll link this addon from my addon as soon as it uploads. My addon is here for now - https://github.com/mozilla/addons/issues/145

This review is for a previous version of the add-on (0.1.3.11).
