Просто необходимое расширение, сильно помогает экономить оперативку, расход батареи и износ SSD диска из-за браузера.

Fixed my YouTube live chat on Opera, thanks!

Please, make it OSS.

Pretty good, thanks for this. Saves space and internet. No issues so far in my used sites

till now ok... But the context menu should not show "add domain to the whitelist", better "allow Service worker". There are many whitelists in my addons ;)

Finally found something to prevent websites from pretending my browser is online when it most certainly is not. I can finally browse hastle free, knowing that if my browser fails to connect to a server, that it won't load a webpage in it's place, so that I can actually diagnose an internet outage whenever it happens without fiddling around wondering why YouTube loads up it's page as if it's online, only to taunt me by telling me that it i'm offline. I miss the days when websites display as offline whenever they are offline. Web developers need to stop messing around with us internet surfers. We don't need zombie websites haunting our web browsers.
