And attention and privacy.
This notice is a great idea.
I might remove the "like" from the notice, since "uBlock Origin" is good, but some others are questionable or even outright malware.
BTW, note that the `ublockorigin.com` Web site that is linked to isn't by Raymond Hill, leader of uBlock Origin. It looks well-intended, and is nicely polished UX, but good practice would be to be careful (since it doesn't appear to be under Hill's control, and is an additional point of potential compromise in what would be very valuable malware). Hill seems to operate from <https://github.com/gorhill/uBlock>. One link that isn't too bad to view <https://github.com/gorhill/uBlock/blob/master/README.md>. Another that isn't great but OK is <https://github.com/gorhill/uBlock/wiki>.
