my system aint slow by all means but Chrome works so much better for me on this x6 AMD Core 8Gig Ram PC than Firefox does, i dont mind Australis, but i have my doubts that i'd like this New in-content stuff, bookmarks etc in it.
Even I don't like Australis design and this change is bumper for me. I agree if only for one or two cycles, Firefox dev try to look into old dead code cleanup and less importing of new and new libraries then they can make a good improvement, like less code less maintenance code, faster build times but structure detailed code, C++11 compliance as much as they can and what not. So there is no doubt yes Gecko is bloated.
I personally don't like Chrome but on laptops where you set Power plan I noticed severe degradation of performance from Firefox Nightly even although that lappy was of i5 and 4 GB RAM. So I think several things to be done before Firefox could reach its prime time again.
i dont wanna be the first to say it but Mozilla is a Dying breed of Browsers, they have left it to long to play catchup and are losing users in the mean time. ( i still love Firefox dont get me wrong ) its just sad to see a once loved Browser turn to ****. they implement unfinished features which turns users away to another browser. but at the end of the day i think all they care about now is Mobile Browsers etc, the Desktop Browser is nearly Dead. . Google Chrome is the New Firefox whether you like it or not.
all Firefox Desktop will become is like Thunderbird at the end when they implement all Desktop Features, if Bug Fix's which is kinda Generally happening now. even Lijnux Browsers do not use Gecko. only Browser i can think of that may use Gecko in Linux an that's Galeon.
