Upcoming improvements: Cookie rewrite
Mozilla just keeps getting better and better. To quote from bug 195908:
to begin improving/optimizing/sanitizing the code, in preparation for merging
everything into nsCookieService. This is the last patch that'll have the files
separate, hopefully. Made things a whole lot more readable, created a new
prefobserver (ditched the old callback system), fixed cookies to be written out
in order (bug 188850), optimized some codepaths and refactored things...
