I just yesterday downloaded the first beta for Firefox 4 and it seems like quite a new redesign. There is a all new layout and this thing is really fast. Lots of articles around which makes me think that I am not the only one that is really interested and excited about a new Firefox release. Lifehacker has an article about features, as well as an article about the new Firefox 4 layout, and Mashable also has some info on the new beta release.
I am sure we will see lots more about Firefox 4 but I was busy also playing with extensions in Firefox 3.6 yesterday and I found that with my 15 or so extensions running everything was slowed down from launch time to page load time so I disabled all but a small core and everything seemed to be a lot better.
One thing that I would like to see is a breakdown of the performance hit before I download and install an extension for Firefox. A kind of cost associated with a plugin to decide if I am willing to sacrifice a second or two or 10 of page load time to have that extra functionality. We all go through times with Firefox where we are adding lots of cool extensions and then just leaving stuff on that we do not really use until the next time that we get excited about extensions again. One of the real reasons that Google Chrome is so fast is that most of us are not adding extensions to it as fast and have a more pure browser with lots of speed still.
