Rated 3 out of 5 stars
This is an impressive and beautiful theme that impersonates IE7/IE8 quite well. I'm using the latest version (184.108.40.206) with FF v3.5.2. :)
This theme will, however, turns your browsing experience into a crawl one. When compared with other FF 3.5.x themes, or even the default one, myFireFox theme is Monstrously SLOW!
Sincerely hope that developers will pay some attention into performance issues too, in future releases.
Rated *** (3) because of slowness.
