Comment (by daira):

 Replying to [comment:3 zooko]:
 > Is there a way to make the Javascript pause when the page doesn't have
 focus?

 Yes, using the {{{window.onblur}}} and {{{window.onfocus}}} events.

 (In ticket:1375#comment:3 it was suggested to use
 [https://developer.mozilla.org/en-US/docs/DOM/window.requestAnimationFrame
 requestAnimationFrame], but that seems to be designed solely for
 animations, since "The repaint may occur up to 60 times per second for
 foreground tabs, but may be reduced to a lower rate in background tabs."
 60 times per second clearly isn't appropriate here.)
