Streaming Torrents (Get a VPN before torrenting!)
Torrent Clients - Qbittorrent, Deluge, Tixati, Bitlord
Nyaa (Anime)
How To Stream Torrents - Copy magnet link of movie you want, open qBittorent, press ctrl-shift-o then paste your link. Start the download. Now right click on the file and select "Download in Sequential order." Give it a minute or two and when you're ready right click the file again and select "Preview." Most clients work similarly.
Adblockers
NOTE - Many streaming websites will swarm your computer with popups. With these tools you can turn even the most popup heavy website into a usable one.
uBlock Origin - Better than adblock in my opinion.
NoScript or uMatrix - If you have never used a script blocking addon before I recommend NoScript. That said uMatrix is much more powerful and precise if you can figure it out.
