Back Up Browser

I currently use Pale Moon as my default but as IE hardly works for me I am considering installing another browser for back-up. Can you guys recommend something that will work with Vista and is lightweight, secure and fast?

 

There aren't many (if any) more lightweight browsers than Pale Moon but this one could be a back up:

K-Meleon is based on the same Gecko engine as Firefox and is very fast.

Tor Browser Bundle is the best for privacy protection and is very secure, but not very fast because of those protections.

Thanks for your replies chaps . My bad, I didn't realise that there was a browser review on 'Geeks'. I will check it out.

 

Any thoughts on Comodo IceDragon?
