One easy configuration change is limiting animated images. Double-click image.animation_mode in about:config and change it to 'none' to stop all animated images, or 'once' to let them run through once. You can revert to the default behaviour with 'normal'.
yes sure google Chrome is the best browser, when i was using chrome, my internet browsing was running at a lighting speed, i
even checked my speed http://www.scanmyspeed.com/
and it was normal subscribed 5Mbps, i was using firefox which chocked my browsing capabilities .
But the only one advantage with firefox is that it has more add ons, which makes things much easier
