V 1.5.0 - Bug Fix: Muted websites wait for the site to complete loading before muting. So if an audio starts playing before website has completely loaded, the sound comes through. This has been fixed.

Bug fixes:
Fixed icon width
Changed icon color with outline to be better viewed in dark themes.
Fixed wrong icon seen on websites with mute and unmute reversed

New:
Added shortcut ctrl + alt + m to toggle unmute and mute, based on a user's feedback.
