Tabbar Broken Rated 5 out of 5 stars

I'm using Firefox4.0b11 with "tabs on top" disabled. When I install Webmail Notifier it breaks the Windows (7) interface integration and it makes the background of the tabbar the same blue solid color as the WN-toolbar. Even when I disable the toolbar through "View -> Toolbars -> WebMail Notifier". I really like the extension, but I don't want it messing up interface components that have nothing to do with it.

Had a nicely quick response from the developer and this seems to be a problem with Firefox itself and also occurs for other add-ons with toolbars.

This review is for a previous version of the add-on (2.7.4.1-signed).
