uBlock Origin -> My Filters
anysite.com##+js(aeld, /blur|focus|afterblur|mousemove|visibilitychange/)

Works. Make sure to toggle it for the sites you need it to work on.

Works great for coursera.org courses on Rhyme

Thanks a LOT

Perfect. Just tried it on localhost and the event for visibilitychange (active) is only fired once during load

YOU MADE MY DAY

love your work. this one hasn't noticeably let me down like the other visibility api spoofers. ~ works perfect on multiple tabs on twitch, & youtube.
(but also need to disable browser-animation throttling in about:config.)

Great, it really works! Let keep it update! Thanks

Very useful when deal with net lessons that sucks.

thank you so much! does exactly as intended when i'm downloading multiple custom content for my sims games :]

If you open tabs in the background, you NEED this addon. Pages load and lay out just as if you're looking at them, so there's no delay or blinking when you do swap to the tab.
An absolute must with Dark Reader and similar.

Not to mention, added privacy, and consistent website behaviour regardless of your browsing technique. The most underrated addon.
