Tip about fastest Firefox version for a slow old PC?

more options


The new firefox 20 is a recommended PC requirement on a p4 and 512mb.. I have an Pentium 4, and ive tested some of the new versions but theyr really shiit compared to 3.6.28 wich im still using.. The new firefox is running 140mb memory more then the one im using in a Game through the web. It annoys me alot, but still ill like to have an upgraded version due to security etc.

Can someone recommend me the best / fastest version for a very slow PC?

IMO, stick with Firefox 3.6.28. I have a similar old PC and found that it couldn't handle Firefox 4.0 or higher versions.
