Google has made it so you can't watch youtube videos if you have this program active on your computer. By active I mean running at all even if it is disabled for youtube. If you go to settings and turn it off there so that it is not active for any websites then you can use youtube pretty reliably otherwise you will have buffering problems and slow videos.

Excellent blocker on Firefox

In a world full of trackers and corporate greed, uBlock Origin is the only fortress we can trust. It’s not just an ad-blocker; it’s a statement of digital independence. I'm giving 5 stars, but honestly, even they are too few for an application so perfect. Thank you, Sir Raymond Hill, for staying an idealist and giving us the power to reclaim our privacy. 1,200+ blocks in one session and still counting. Pure perfection!

most important thing on HyperTextTrasferProtocolSecurity

This is an essential tool for all Mozilla Firefox users; it's nearly perfect and comprehensive in providing the default browsing experience. It's free for everyone because privacy is everyone's right. Thank you.
