I like Firefox 4, it's pretty good, but frankly not good enough to turn me away from Chrome. I tried using FF4 for a day, but after about 30 seconds I missed the Chrome address bar, and how smart it is at figuring out which page I'm going to before I finish typing. I know that shouldn't be a game-breaker, but I'm so used to it now that going back is like losing a finger. I do like the new FF UI, even though it is embarrassingly close to Opera, like completely copied. I could make a big impassioned speech about how open-source is inherently derivative and never innovates, but I'll hold it in for your sake. All in all, I give it 4 out of 5. Good, but not OMG good.
My FF4 does the same by deafult. I've tried other browsers and got the exact the same feeling, it's called detachment to something and just the fact that you are used with one certain browser. Switching to new gets you slightly confused and makes instantly feeling that it is missing something since you are used to something different. Force of habits.
that's the same reason I can't leave Firefox...because of the awesome bar it's the best address bar in any browser and once I got used to it, I can't use an ordinary address bar anymore
I like to think Chrome is being done by professionals, and FireFox is being done by Enthusiasts. Both do a great job when you consider where they are coming from, and FireFox should be commended for doing a great job against IE6 and showing the world how bad it really was. But the fact remains, Chrome is more secure and it's where the professional devs are going. This is because of not only the 6 week release cycle, but also because they are fast. Not as fast as FireFox in all metrics at time of writing, but I bet in another 6 weeks it will be. And then FireFox 5 will come out and be faster, but then another six weeks after that Chrome will be faster again. I will pick Chrome over FireFox because even tho FF is now a Browser War Veteran (in much the way Britain was during WWII) Chrome is the USA (coming in late in the game) and will turn the tide against IE and win the browser war.
That being said, I am typing this from a Google Cr-48, so I might be a little bias.
Whoever makes a browser or OS that literally cannot be hacked/infected will make billions. Some say thats impossible but I don't think so. I can't imagine the future when our time-travelling quantum computers get redirect viruses. You want to go to Woodstock in 1969 and you end up somewhere in Russia in 1945.
