Rated 5 out of 5 stars

This Extension is an excellent time-saver for Firefox up to 3.5.*, and dovetails beautifully with Personal Menu 4.2.1 (no bugs on Firefox 3.0.19 on Ubuntu 8.04.4 or 3.5.8 on MS-Windows 7.0.8001). Recommend update for compatibility with Firefox up to 3.7a3-pre for proper testing on Minefield.
