Is uBlacklist safe?

uBlacklist filters search results on Google and other engines using user-maintained or subscription blocklists.

The extension injects into Google Search pages (and optionally Bing, DuckDuckGo, and others) to hide results matching domains or patterns the user has blocked. Users can sync their blocklist via Google Drive or Dropbox. The extension bundle ships Dropbox and Google Drive OAuth client secrets in plaintext, meaning anyone who obtains the XPI file can read those credentials.
