Hi. This extension works fine if you convert it with addon converter, all I did was change max version to 2.49.1 and that's about it really. Also helps if you download and install it manually. Right click on dl link and use "Save target location".

I really like this addon, this and classic ff (which btw also works if you convert it) theme turn sm into the firefox v 3/3.5, it's the first firefox version I ever used. Default sm is ugly for me, it might also be that I'm not used to the default sm style, since I've never used the "Mozilla" browser/internet suite. I have setup sm just the way I like, there are still some things that bother me (nothing to do with this extension however), but overall this addon helps a lot.

If you're considering adopting sm either as your daily browser or just as a backup, this addon is definitely recommended!
