uBlock Origin is the only browser extension I use on Firefox, Even after loosing trust on browser extensions in general after witnessing a recommended Firefox add-on indulge in malicious activity[1] and reading numerous stories of how browser extension publishers with large number of users are routinely approached to integrate malware.

The reason why I cannot do away with uBlock Origin is because its not just an Ad-blocker as its philosophy states, I need it to make websites usable by blocking elements like auto pop-up news video player, Blocking side bars to resize the websites to preferred width (When playing videos), Disable tracking and often just to load the websites faster.

To those familiar with the HTML DOM I recommend uMatrix from the same author as uBlock origin. It makes a good companion to uBlock Origin and provides much finer control.
