The new YouTube subscribe button is bright flaming red. How annoying, right? This extension fixes that.
YouTube recently replaced the 'Subscribe' button on video pages with an obnoxious bright red button. That's annoying. This extension's sole purpose is to swap it out with a less-annoying light grey version.
This extension only adds limited CSS properties to target the subscribe button. It does not access your YouTube data or data on other sites, and no data is transmitted to third parties.
