need suggestions about content filtering project

i'm thinking of designing and implementing a content filtering software as my graduation project. i want it to be a user contributed software. i mean, users can also add/categorize websites. it should be also a web project and extensions for browsers like chrome, firefox, ie..

my question is which programming language do you suggest for this project? i know that firefox extensions are javascript based maybe you can say use .net framework 3.5 because it's better in communication with extensions.

sorry for my bad english..

thx a lot.

I would use django or ruby on rails for the web app. I personally would use django but both work work just fine.

I've never worked with browser extensions so I can't suggest anything for that.
