+title: Bypass HSTS (HTTP Strict Transport Security)
+date: 2025-06-09
+---
+
+Got an annoying error, like this:
+
+> `WEBSITE-YOU-ARE-ACCESSING` has a security policy called HTTP Strict Transport
+> Security (HSTS), which means that Firefox can only connect to it securely. You
+> can’t add an exception to visit this site.
+
+And you really need to access the site, and don't really care that whatever you
+are sending is encrypted?
+
+Just `Ctrl-H` to go to history (`Command-Shift-H` if on MacOS), search for the
+site, and right click and press `Forget About This Site`.
+
+This will make your browser completely forget about that site and thus not be
+able to recall the HSTS header, and let you connect insecurely.
