Re: My favorite Firefox/IceCat extensions
You have to try FoxMarks... no more bookmark copies between computers. If you don't trust handing out your bookmarks to strangers, FoxMarks lets you use your own server ! (http://wiki.foxmarks.com/wiki/Foxmarks:_Frequently_Asked_Questions#Using...).
FoxyProxy helps me bouncing on my home proxy from my job ;)
Re: My favorite Firefox/IceCat extensions
The third-party server was exactly what was keeping me from using that extension.
I just installed it since I now know that I can run everything from my home server. :)
