Mozilla is great, I've never had a pop up using it and I can block almost all of the ads on every site I visit . But, I can't stand the flash ads:|. Until now I have been changing the file permissions on npswf32.dll so that I can not access the file but other users on this computer still can. As flexible as mozilla is there has to be a line that I can add to my prefs.js or userchrome.css file to disable flash without messing with file permissions or deleting files. Can anyone help me out?
