Have you tried "uBlock Origin Lite"? It is by the same author, Raymond Hill (gorhill). It has been working fine. I use "optimal" level for the filtering mode. (Note: I use Chromium on Linux)
UBlock Origin Lite pulled from the Firefox extensions after being flagged for policy violation, now only available from GitHub.

EDIT: But yeah, the Mozilla reviewers are very hostile, also had to fight with them for one of my add-ons. It's ridiculous that spam and malware add-ons get a pass but privacy-conscious add-ons get rejected.
