Firefound - finds your stolen computer and cleans your personal data
Sometimes losing your laptop is bad, not only because it is expensive or full of necessary information, but also because there may be a lot of data that is meant only for you. Firefound is a handy Firefox plugin that will allow you to find your laptop and destroy all personal data on it in just a few simple clicks.
After installing the plug-in, Firefound uses geolocation to determine your current location and sends this information to (your, if you like) server. If your laptop is lost, you can get into the Fifefound web interface and find out where your laptop is now, as well as delete all your personal data.
Security levels are configured in such a way that you can, for example, receive letters if your laptop is used further than a certain number of kilometers from your location, but it is even more convenient to delete some or all of your personal information in the browser if the attacker fails to enter the correct password from the N-th attempts.
