I really dont know about IE6 issues. I've used Mozilla since v0.4 and switched to Firefox at v0.8.
Its like, the page is 'heavy'. Ok, I dont know the impact of my many extensions. Think the Tidy Validator and js console takes some ressources as well as adblock, theme and toolbars does.
hmm.
anyway, where's the server located ?
Note to self: Test phpBuilder.com/forum/ whenever firefox gets reinstalled. 😉
