Better than SpeedDial Rated 5 out of 5 stars
One of my must-have addons. It's fast, easy and significantly helps to open up my favorite pages. It is much more convenient than SpeedDial or BooksmarkBar, and that's because I do not need to open a new page, and each additional bar takes additional screen height, which I would prefer to use the website. And since there are groups and columns, it is easier to classify links.
Apparently the Mozilla developers are planning, in the near new version of Firefox add SpeedDial to a new tab, but I think they should try to be more original and talk to the author of SiteLauncher to add this feature.
