Hosts file are a useful redundancy when coupled with ad blockers like uBlock Origin and uMatrix - while debugging or 'Temporarily Allow All on this Site' with Noscript can open you up to underlying attacks or privacy intrusions.
In-browser filters won't protect you if the browser itself is phoning home.
If you have an up-to-date hosts file, the risk is severely lessened.
Auto Hosts will automate the setup process for maintaining an up to date hosts file, by:
- Installing a weekly cronjob to pull a copy of Steven Black's Host file (default is every Sunday at 7:22pm) - Appends Facebook trackers, Linkedin ads, Google fonts, Firefox telemetry and other harvester sites that curated lists for whatever reason, have not added to their blacklists - Refreshes DNS to instantiate the re-routed changes (Mac Only) - If Devdom is installed, append all local virtualhosts
