Pale Moon

It has a lot of the bloat from Firefox stripped out of it but its biggest weak point is the dev's refusal to use WebKit addons, so you will have to spend a little extra time to make it work (lots of people ported some addons to work with Pale Moon), but the dev is fucking autistic about making the browser free of bugs and security holes.

The browser has a shitload of options and you can make it look almost exactly like Firefox 3.6 before they went into that stupid rapid release cycle

Pale Moon is no longer a full fork of Firefox as well. The dev actually ports the security fixes from the primary Firefox branch, but internally apparently Pale Moon is very different from FF aand has its own UserAgent string as well.
