Guarda-Frames 作者： willehersomo

Guarda-Frames is a defense layer against malicious artifacts commonly found on web pages.
What it does:

Detects and removes invisible overlays and iframes that hijack your clicks (clickjacking).
Blocks popunders (windows/tabs opened without your consent).
Holds unsolicited redirects and shows a confirmation screen before sending you to another site.
Neutralizes abusive meta refresh and back-button hijacking.
Optional domain blocklist and an exportable log (JSON/CSV) of everything blocked.

Privacy: all processing is local. The extension does not collect, transmit, or sell any data. Interface available in English and Portuguese.
