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. There's definitely elements of code improvement involved, but it's not the main reason why things are 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?
• Switching tabs while loading several tabs seems slow
