FAQ

1. Is there a way to do profiling of what is going on in Mozilla? Is there a framework for this?

A. If you're on Linux, then you can try using jprof.  Instructions  are available at    
Jprof Readme  On more recent linux versions sysprof can also  
be used. [1] also lists some profiles.

2. How do you findout if there are any reflows that are pending and wait to show the view until afterwards, but if none are pending, show the view immediately? What is the best way to determine whether there are any pending changes?

A. On the reflow branch you could check the DIRTY and DIRTY_CHILDREN framestate 
flags.  That won't help with pending style changes, but it'll work to detect 
cases when the popup or something in it needs to be reflown.
