StayPut

Warns before you reload, leave, or close a page so unsaved input (e.g. grades) is not lost.

StayPut – Don't lose unsaved changes. StayPut warns you before a page is reloaded, left, or closed, so unsaved input (for example grades typed into a school system, a long form, or a comment) is not lost by accident. Features: - Change detection: by default it only warns once you have actually typed into an input, textarea, select, or editable field. -Warn even without changes: optionally always warn while a page is monitored. - Site patterns: restrict protection to specific addresses, or leave the list empty to protect all pages. Wildcards * and ? are supported. - Per-tab pause and "Mark as saved" directly in the popup. - Status badge on the icon: green ON = monitored, red ! = unsaved changes, off = paused. Available in English and German (auto-detected, with a manual switch). Privacy StayPut works entirely on your device. It does not collect, transmit, or sell any data. Your settings are stored only in your browser. Note For security reasons the browser shows a fixed warning text that cannot be customized. The dialog only appears after you have interacted with the page at least once (a browser requirement).
