The new browser is out, and with about 7 million downloads and 3 or so hours left to set a new world record, Fx3 has managed to eat more memory than Fx2 ever did.  With Fx2, I capped out at ~70mb, even with multiple tabs left open overnight.  Fx3, in mere minutes gets up to 100mb and surpassed the 200mb mark.  I did notice that a huge jump happens when watching video.  YouTube may just bring Fx3 to its knees.  I have no idea what the guys over at Mozilla did to make it where video takes up so much more memory, but they did it wrong.

The pros are that it gives back the memory fairly quickly.  After getting away from YouTube and CommandN, and logging into WP, I’m back down to 53mb, which is acceptable to me.

There is a big push for IPTV going on with companies like CommandN, TWiT, Revision3 and others, but Mozilla may be trying to put a stop to it singlehandedly.  Hopefully they’ll get this resolved.  Fx3 still works when using 100k+, but no other programs do.

UPDATE: Just installed Fx3 on my laptop and it’s exactly the same.  Jumped to around 90mb when watching a video off a Yahoo! site and 6 tabs and then back down to mid-60mbs when I went down to only one tab.  The problem here is that Fx3 may not be able to run well on older machines that have less than a 1Gb of RAM unless they fix this.  What happened to using less memory?!?!
