The Browser Lock από Edrees

THIS IS NOT supported or sponsored by any of the mentioned entities or any other entity. Some web forms lack a safety/warning mechanism to protect data. I designed it to support Smartsheet, Microsoft, and Google Forms. It prevents data loss when the user accidentally refreshes/closes the tab or browser. An alert message should appear to the user to confirm the refresh or the tab's closure. To work, the user must first interact with the page. At least click anywhere on the page.

End of Service
I am planning to retire the extension (End of support); the extension is completely free and has never been supported financially by any party, not by Microsoft, or Google, or Firefox, or Smartsheet, or even by any user. I designed it to solve a problem I have observed. I encourage you to seek another alternative. Feel free to uninstall it right away; I will release a new version to trigger uninstall as soon as possible.
