They re-wrote the engine. It's DOUBLE the speed of the one from 6 months ago. It also uses less memory.Did you do it yet? Wondering about any glitches. I sure hate the FF I'm using now. Freezes a lot and is slow.
Freezes may be from ad-ins.
But since this is a new re-write, I'd try it since it also does a new install, so it may "fix" stuff. As far as "glitches" go...who knows? But it's working so far for me.
And it's faster than Chrome.

one hour of weeding more than enough!
