I have used the same browser for years. I used Palemoon browser (firefox derivative) which has been optimize for speed and 64 bit computers. It does not have all the bells and whistles as Firefox, but it is my browser of choice. Examples of bells and whistles, parental controls, etc......
If WGT wants to get more information on this browser check out their website "Palemoon.org"
Secondly, I do not like using other browsers. It was WGT that suggested Firefox to begin with, back in 2009, and I am glad that I switched to this browser. I have had no problems surfing the net, in private browsing mode, or using this site.
