Setting multiple interval timers to run simultaneously causes the timers to become completely unreliable in Mozilla/Firefox and iCab.
In most browsers there is a slight variance between the requested timeout and the actual timeout (a few miliseconds per one second timeout). This is normal.
In Mozilla/Firefox, using multiple interval timers causes the intervals to be far too short (a fraction of the requested time), followed by one extremely long interval to make up for the short ones. This pattern then repeats.
