Was a once great extension. Now I'm seeing really annoying behaviors. For one, the color of the tabs constantly change in Windows. In Linux it causes it to rapidly jump from one tab to another. I understand that this may not be entirely the developers fault. Part of it is the buggy framework Mozilla has set up for extensions, which is unfortunate. What separated Firefox from other browsers used to be my ability to customize Firefox to work the way I want to. As it stands now, other once great extensions no longer work correctly or are severely crippled. Not sure why I should continue to use Firefox over Chrome
