Since that "JS Virus" thing a month back? ish, ive decided to take "no chances" - and came across a very nifty script called "Noscript" - Does what it says on the tin!
http://noscript.net/
(Btw, visited one of the sites that were affected today...anyone know if it was sorted out? - Im a bit paranoid about it still - **cuddles PC**!!)
Thanks, Avenger, a useful extension. I don't know whether all sites have sorted their problems, but the ones I visit have. Good old NOD. :)
Also try adblock for firefox with the updater..google knows where it is >:D
