Nope, not always.

I already had those nice bugs, when a code was 100% valid, that FireFox displayed it incorrectly.

But the best thing was sometimes it displayed the page wrong, then after a reload correct, after another reload wrong again.
Definitelly a bug, and it was very annoying as i had to rewrite a lot to still keep the page 100% valid, and looking as it should and does on IE.

Well, as said, no browser is perfect...

my biggest problem is i use firefox, so i make it work perfectly with firefox and w3c, then i view in ie and its borked so have to start all over :P

definitelly ^^

the trick is to check both as you go along, then you can kill the bugs as they come up not when you think your finished only to see what a mess it looks in another browser, we've all been there at one point or another :)

I've never had a problem with Firebird (fox, I know, but I refuse to call it that :p)

Satan

well the problem isn't firefox itself, its the fact that you have to constantly check both about 4 browsers to get a site working in all :p

Not if you learn to code correctly :) ^^

Ditto what dean said, code to standards, errors wont be many :)

firefox is my default browser and i can say it even renders some ++++ely done sites, it's worth the download

although Tab Browser Extensions don't work with vBulletin

I stick to IE and I think many people do the same as I do, that makes the difference ;)
