Excellent alternative to AdBlock and similar extensions, because of lower CPU/RAM usage and better support for 3rd-party lists.
However, by using the latest stable release (v1.22.2) I lose periodically all subscribed lists, so the browser navigation freezes until I disable/reinstall uBlock.
The issue is fixed in v1.22.3.x beta, I hope you'll release them in stable branch asap.
Actually I'm downloading uBlock beta from the official Github repo.
