Is Firefox dead?

Far from it. Firefox 4 has hardware acceleration and a rebuilt java engine. Im from the show me state that said i been reading that IE9 is a hole new beast. But.... firefox is solid and the addons are just and solid........

I use Firefox, no one has the same add-ons that I want to use and it works fine, it does tend to crash every now and then.

I don't think it's dead at all. Firefox's extension still beat out Chromes and certainly beat out Safari's hands down. My Firefox is actually faster than Safari. I've tried numerous times to use Chrome and I just don't like it, and still to this day have problems with it not displaying information correctly.

So no, Firefox is not dead and will not be for a very long time.

A better question to ask is when the hell will IE die?

Update: IE 9 is actually very good especially for a beta

It won't die out, because sadly IE still hasn't died out.

I think the Webkit based browsers are too fast, but on the stability point i don't agree. Some apps based on plugins (like Flash or Java) just don't work on Chrome or Safari. For me they are just faster, but stability and reliability is still better on Firefox. With the growing of OpenWeb technologies (HTML5, CSS3, WebGL, WebM, and others) and the adoption of them on web apps development, i think the differences will vanish.

no way firefox would die. 1st its AWESOME. then it has so many addons and features that make it just good as(if not better) than safari or chrome. See speeds not allways the most important.

I hate Safari and I hate Chrome, but I love Firefox. No, it's not dead.

I do not think that it will die out for a long time however I do switch between browsers I like Safari and will be switching to a Mac soon which will have Safari on it. I love Firefox and do use it however when IE 9 releases that will probably become my main browser as I also like IE. I have always believed IE to be the most secure.

Firefox have upped the anti on their vulnerability finding mechanisms. They now offer 3000 pounds to anyone who can find a remotely exploitable vulnerable, up from the 500 pounds they previously offered. Firefox is far from dead. This is the incentive they needed. Firefox will improve drastically in quality.
