Is uBlock Origin safe?

Blocks ads, trackers, malicious URLs, and other web content using configurable filter lists.

This extension applies built-in filter lists including uBlock Origin filters, EasyList, EasyPrivacy, Peter Lowe’s list, and an Online Malicious URL Blocklist. Users can enable additional lists for annoyances and host-based blocking, block JavaScript locally or globally, and create custom rules to override filter-list entries.
