Thanks for those links. While the earlier versions for Safari (like v0.8.2.0, found here https://github.com/gorhill/uBlock/issues/117) work well on Safari 5, these new versions on your Safari link do not. They crash the browser during installation.
Seems to be this issue: https://github.com/gorhill/uBlock/issues/547
Safari is on version 7, why would you care about v5?

Yeah, I've used it on Chrome for half a year now. The news is that it's now available for Firefox.

Opera: https://addons.opera.com/en-gb/extensions/details/ublock/
Safari: https://chrismatic.io/ublock
Haven't tried it out myself yet but it's nice to see effort put into lowering the memory & CPU usage of such blockers.
