It looks very similar to Chrome but it's much faster that 3.6.

If anyone is using Roboform to manage their passwords, it will not work unless you purchase the upgrade to Roboform v.7.x. So, now I'm stuck until I can upgrade my Roboform. However, I do like the speed of FF4, although I'm not very enamored of the look of it.

I was having some serious lockup issues with Firefox 3.6. Firefox 4 is definitely much better.

I hadn't had any lockup issues with FF3.x. FF4 is definitely faster, but I still don't care for the layout of the tool bars. They take up a lot of real estate due to a lot of space between then that wasn't there in older versions.

I am using the Firefox 4 it's Best...

They still need to trim the empty space between the tool bars. If I could return to v3.x I would, but I've already spent too much money on getting one of my addons to work with v4.

Anyone notice that you cannot control cache size with FF4? Oh, it says you can override auto cache control and set the max size but does nothing. I noticed serious disc thrashing with FF and found the cache was over a gig. It took 20 minutes to clear the cache! The next time I used FF 4 the disc just thrashed and thrashed and still does it now and then.

Anyone else getting this behaviour?

I just checked mine and it's using just over a meg.

FF 5 beta is now available
