Does not work to stop Facebook auto refresh.

very nice extension

Worked for one day only.

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

I install this add-on only for one thing - to disable auto refreshing Facebook news feed. It work well! But when I found one side effects - you can't make posts on web version of Instagram. Always have a error "Your post could not be shared. Please try again". So sadly I can't use it(

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

Works great for coursera.org courses on Rhyme

doesn't work

Thanks a LOT

it is greyed out and couldn't use nor pin it

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.
