Saviour of the Internet

The BEST tracker/ad blocker : completely open-source, managed by volunteers, and very light on RAM/CPU resources!

It's completely broken. After 30 seconds no data from any website can be loaded and my CPU goes into into overdrive. The second I disable Ublock the temp drops rapidly and everything starts loading again. Tested multiple times. Was great while it lasted but it is unusable in it's current state.

Really useful extension

Superb.

The extension often doesn't open when you want to disable restrictions for some sites.
