How to automatically pause JavaScript in all Firefox background tabs without unloading them?

Question

Mozilla Firefox

I would like it to be simple: so that an inactive tab simply does not load the processor. And when I return to it, then to make JavaScript work again. On any page there can be, for example, the entered text in the input field, which should not disappear. In general, the state of the page needs to be saved. Memory consumption is not important.

Answer 1

no way))
