Rated 4 out of 5 stars

I am using version 3 beta on Firefox 4. Sometimes colors on tabs(probably the first one) do not appear until the tab is hovered once. Also with tabs on top it does not smoothly blend with the navigation toolbar and should be fixed for the active tab. Perhaps you may keep active tab in default color, or maybe you can extend the idea of tabs-bottom to the navigation toolbar. Also the title chenged notification for app tabs no longer holds. There should be an option to handle that. Keep up the good work.

When will this be updated for Firefox 4?
