UBlock Origin shares the same codebase as uMatrix, which performs a similar job, but which is aimed at more advanced users. We cannot emphasize enough that uBlock Origin should not be confused with uBlock, the latter of which is now owned by Adblock Plus and participates in its "Acceptable Ads" scheme. Developer Raymond Hill “self-forked” uBlock Origin after transferring the original uBlock project to a different developer in 2015, after which time the two projects have been completely separate.

Usage: The big power button in the popup is to permanently disable/enable uBlock for the current web site.
