FireFox very slow on Win and Linux

[techlists at phpcoderusa.com]

Hi,

I was thinking it was my machine.  I'm running and i5 with 8GB RAM and 
Kubuntu.  And I was also thinking it was my connection.

Right now I was trying to reach a website on my local dev box and it 
timed out.  I went over to my Win laptop and the site came up. So I 
decided to try an alternation browser on my Linux box.  It came with 
Rekonq.  WOW it was snappy.

I know others have complained also.  Maybe it is time to move on to 
Chrome or something else.  Both FireFox and Thunderbird have been slow 
for me.  I move from Thunderbird to KMail and it seems to work much 
better.

Any thoughts on why FireFox would be so slow?

Thanks!!

Keith
