Firefox 4.0 is out

Pic somewhat related. :P

The official, non-beta Firefox 4 was released yesterday...
http://www.mozilla.com/en-US/firefox/new/

"a new look, super speed, and even more awesomeness!"

If you're running 3.6 you'll have to manually upgrade to the new version.

It is quite a bit faster, but the new hardware accelerated rendering makes my MacBook Pro switch from Integrated to Discrete graphics which drains the battery.

And scrolling is messed up. You can scroll, but in the background, you can see parts of text/code scrolling down with you. Just try it on F, scroll down a little while looking at the sides. It's... annoying, to say the least. Unless it's just happening to me... :C

LEGN....wait for it.......DARY!!!! The Gremlin likes. Firefox 4 gets my seal of approval anyday. No problems whatsoever, and I like that they compressed that somewhat bulky and unwieldy bar setup at the top of the page. Moar room to view pr0n and anime!

Hm, haven't really dabbled with it much, but so far it seems alright. I haven't seen anything yet that makes me go "Ooh wow! This is so much better than Firefox 3!" but I haven't seen any problems either. Hopefully I'll like it even more as time goes on.

It was a bit annoying upgrading on Linux but its enjoyable so far.

The new font rendering is still a bit weird for my eyes, but i'm starting to enjoy it. A nice update, but not really a revolution. (I though i was on Opera 11 after updating ^^;)

Updated it tried it kept getting error messages tired of it now

I tried it yesterday, and it runs nicely on my office PC. Has a minimalist mode similar to Chrome, and runs faster (Chrome keeps messing up Shockwave and crashes on it quite often)... I'd switch to it for now since I'm getting tired of reconfiguring the proxy settings for IE (and subsequently, Chrome since it uses IE's proxy) every restart of my office PC. And I program web applications, so a new Firefox browser will be another new platform for me to test my application for browser issues going forward.

But my personal laptop, I'm sticking with Chrome. FF4 has no Hatsune Miku skin yet.

Lol I use chrome and I barely get any plugin problems unlike firefox where it keeps having problems it's pretty odd

I installed Firefox 4.0 1 hour before. I have to say it´s quite the same just the graphic display have changed (looks nice). It have some new additions, didn´t check them out yet.

Wait, I'm using one. In fact, it's the top rated skin on mozilla's persona page.

The real upgrades this time around are under the hood...

...and yay! HTML 5 beat Silverlight... one more fiasco that was averted.
(Anyone remember the shit around ActiveX components?)

Why do I mention HTLM 5? 'Cause that's pretty much what FF4 is about. Expect some nice & dynamic things done with it when the technology propagates among web-developers.

Yeah. That's what I assumed. I'm seeing nothing spectacular about it, but I don't claim to be a web-nut, not in the slightest.

My only problem is... I always end up opening a new link in a new window rather than a new tab with the right click button.

...use middle-click. It opens whatever you click on in a new-tab. Middle -clicking a tab closes it.

CTRL + Click. Works too for those who don't use a mouse or strangely don't have a scroll wheel

just updated ive been using google chrome for a bit

Still like chrome more, although the 4.0 is still pretty nice.

Yeah, the same with me...
