Have not seen this posted here and I believe it is new. Tried it out yesterday and could be very useful and protect people from fake websites etc so I thought I would share.
FMHY SafeGuard is a browser extension that keeps you safe by checking websites against the latest filterlists from FMHY Filterlist. The extension categorizes websites as starred, safe, unsafe, or potentially dangerous, giving you peace of mind while browsing.
Key Features
- Real-time Site Status: Instant feedback on whether a site is starred, safe, unsafe, or potentially unsafe, with visual toolbar icons.
- Updated Filterlists: Utilizes the frequently updated FMHY filterlist to ensure protection from the latest unsafe domains.
- Pop-up Alerts: Get easy-to-read pop-ups that inform you about the site status and allow further action.
Is the database of websites installed locally in the extension or is it calling home for every website I visit?
all three filter lists are fetched once and kept in memory when the extension is initialized (from what i can tell this happens when the browser starts), and then that local copy is used to match URLs.
For reference, the source file is background.js
URLs at the top, init calls at the bottom, and above that the event registering stuff (tab nav and nav).
Looks like the block list itself is maintained here
