BebraCheck

About

This simple extension is designed for users of anonymisers.
BebraCheck helps ensure the overall security and privacy of your browsing experience by showing possible flaws in your online privacy.

Here is a complete list of features.
BebraCheck:
• shows your approximate location based on your IP address;
• notifies about possible mismatches in your language or time settings;
• check if it is possible to detect the use of anonymisers;
• estimates your IP trust score.

The worse results you get - the more suspicious the sites will be about you. The more often you will have to pass captchas. The more often your freshly created accounts will get instabanned.
