Perceived Performance

The aim for the "Perceived Performance" effort is to identify changes we can make that will make Firefox feel faster — as opposed to the classic optimizations that generally involve rewriting code to make it faster.

Add your ideas for things we should look at to make Firefox feel faster below:

• Load the frontmost tab on startup before the others (filed as bug 496458)
• Don't show the progress spinner for the address bar until 200-300ms have passed (it currently appears instant, and makes it feel like you're waiting for results).
• Color changes when creating a new tab
• Startup order, what tasks are performed on startup, and is there anything we can defer to make the startup experience faster?
