I was just testing that new version of FireFox, it is on a Beta stage, it was freezing as I was trying to use it here at L.P.
I don't know what the problem is, but either it is not ready yet or L.P. is not ready for it yet.
Either way, I just quit using it and deleted it, I was trying the portable version and I find that somehow it changed a little my 3.6.12 version of Firefox, it was not a good idea maybe to have both of them at the same time, even if I was only using 1 of them at a time.
I must say that this older Firefox version is also portable, whenever I can I use portable software instead of the ones that have installers, but no matter what, they don't seem to be completelly self contained on their own folder, some stuff seems to "leak" out of it elsewhere.
They say that Google's browser is the fastest now, but I have not tried it and I might not anyway as I like Firefox, at least so far I do.
