Chrome does conditional breakpoints - just edit the breakpoint and type your condition in - but it massively slows down the page of that code gets hit a lot.
So much so that I prefer to put the condition in my local build as source code then put a normal breakpoint on that after it has rebuilt (a few millseconds with a good watcher)
