content: Consider switching from ABP to uBlock. ABP is backed by commercial interests due to their paid whitelist. uBlock supports all the same blocklists but is completely free/open-source and non-profit. Ghostery is also owned by an advertising company and the optional “Ghostrank” feature collects information on ad trackers and sells it back to advertisers. It may appear harmless but that is some serious conflict of interest. Alternatives to Ghostery are the EFF’s Privacy Badger and HTTPS Everywhere extensions which cover similar features. *Correction: Ghostrank collects information on ad trackers, not blockers.
