Plugin Side Panel
The checks in the side panel. TagSpion reads the open page locally in your browser and shows what is missing, with ready-made code to fix it.
The panel opens via the TagSpion icon in the browser toolbar. At the top is the to-do list with all errors and warnings, below it the sections. Every row has a traffic light: green is fine, yellow could be better, red is missing or wrong.
Everything runs locally. TagSpion only makes external requests (DNS, certificate, your IP) if you allow it in the notice dialog.
