Didn't work for Twitch

Works great on mobile, thank you.

Very useful!

works perfectly, this should be built into the browser itself, the user should have the option to choose if they want to allow or deny access to the Visibility API.

Works as advertised!! FFS, this was incredibly frustrating issue to have, but this fixes it.

Wors exactly as expected. Pages do not know they are not "focussed" anymore and don't pause the download countdowns.

Works like a charm! Thank you! :-)

very good

Great at bypassing that annoying "feature" on some sites that pauses a video if you tab away (for example during a commercial). The only thing that could make it better would be if it offered a toggle button that you could put in the toolbar to switch it on and off.

Thank you!

It also works on Instagram videos.

(so this is a good app if you get annoyed by stupid instagram deciding for me to automatically pause playing videos whenever I click another tab)
