If you're not happy with FireFox, use Opera.
..."Firefox is getting more and more bloated and buggy with each release, and their bookmark manager sucks farts from dead goats (in 3.0 beta as well damnit)"...
So use Opera. No need to download all these sodding "extensions" to do simple things like blocking ads or JavaScript or iframes etc. etc. either for a site or globally - Its all inbuilt in opera, aloung with ither useful features likes notes, the ability to apply a custom CSS style to a page and a zoom function which actually *works* (allows you to zoom images and controls too, not just text).
Pity so few people use it - personally I've always rated Opera far above the likes of IE, FireFox (which is by no means bad, but I preferred "Phoenix" when it existed) and Safari.
Such is life.
