UBlock Origin

uBlock Origin ( "you-block") is a free and open-source browser extension for filtering content, including ad blocking. The extension is available for Chrome, Chromium, Edge, Firefox, Opera, Pale Moon, as well as versions of Safari prior to 13. uBlock Origin has received praise from technology websites and is said to use much less memory than other extensions with similar functionality. 
uBlock Origin's purpose is to give people the ability to enforce their own filters for blocking.
uBlock Origin is actively developed and maintained by its creator and lead developer Raymond Hill.
