Biblioteques de Barcelona WiFi Auto-Login by lfarina

Automatically logs you in to the public WiFi at the Barcelona metro-area libraries (Xarxa de Biblioteques).

Save your carnet/DNI and PIN once in the extension's settings. When the library WiFi login page (xsf-biblioteques.diba.cat) opens, the extension fills in your details, ticks the terms box and submits the form. If the login fails, for example because of a wrong PIN, it shows a banner instead of retrying in a loop.

Privacy: your credentials are stored locally in your browser and are only sent to the library portal itself, as if you had typed them in. There is no analytics, telemetry or third-party server. Note that Firefox stores extension data unencrypted, so don't use this on a shared computer.

Unofficial: this project is not affiliated with, endorsed by or supported by the Diputació de Barcelona.

Vibe-coded: this extension was almost entirely written with an AI coding assistant and has had limited human review. The source is four small files.

Tested at one branch so far (Centelles). Reports from other branches are welcome on GitHub.
