Nice list, there Bitt. I will be trying a few of those out.

I personally don't like NoScript, as it's too intrusive and makes many web sites stop functioning properly. Everything that I'd want done with NoScript is handled already by AdBlock Plus.

My own addition: I giggled when I saw Filler Item yesterday. Don't know if I'll ever make actual use of it, but once you install the Firefox extension, it's easy to use. Brilliant idea.
