Changelog

1.0.0 — 19 October 2026

Complete rewrite (Manifest V3), desktop and Android.

Addresses are checked before the page loads, so fake sites are caught even when they do not answer. Version 0.0.5 only checked pages after they had loaded.
A full-page warning stays until you decide, instead of a notification that disappears. Buttons to go to the real site, go back, or open anyway (once or always).
Far fewer false alarms: legitimate international names are no longer flagged as phishing. A page is stopped when its name mixes alphabets, uses only look-alike letters, or imitates a well-known site or one of yours (Unicode UTS #39 data).
Also catches plain-letter tricks against well-known sites (paypa1.com, rnicrosoft.com).
Explains the trick: highlighted letters, Unicode code, alphabet and the letter they imitate.
Toolbar icon in three colours; panel with the verdict, “trust this site” and a manual address checker.
Options: three protection modes, trusted sites, your own sites to protect.
Works in Firefox for Android; light and dark themes.
No notifications permission and no network requests.

A content script compared the page address with its Unicode form and showed a notification.
