Description

Here described this problems for timeouts, and in the same article described the solution for it:

Firefox 50 no longer throttles background tabs if a Web Audio API AudioContext is actively playing sound.

This small package initalize AudioContext on the page for modern browsers and using this tricky way all timers no throttling more. As easy as possible.

WARNING! Be careful and use this tool only if you really haven't any another ways, browser developers don't just put a lot of effort into optimizing and firstly try to experiment with:

• WebWorkers
• requestAnimationFrame
