Like other old users of PC,testing for new stuff is a nice thing.FireFox 3 beta1 was released on past several days and these days I try to use it to test its enhanced performance.
Upon my testing,I feel that this version of FireFox is more efficient on loading pages than others(including Maxthon),and better on loading pictures too.But since it is a beta version so that some of bugs still exist.According to the official release guide,it will be another beta appeared at the end of December and one more beta on next quarter.After that the final version of FireFox 3 can be shown in front of us.I hope that the traditional problems of FireFox(high occupancy on CPU and RAM,compatibility on displaying websites etc) can be improved or solved.
My conclusion is it is worth testing it.
