# Why is it not effective to use our proxies in a fingerprint browser？

***Note: When you use our proxy with a fingerprint browser, there will often be some problems that affect your use, such as the proxy does not take effect due to configuration errors, the conflict between the IP attribution of the user's self-test and the IP attribution at the time of extraction, and the random IP attribution caused by incomplete account password input. Since IP attribution judgment is a very complex process, in order to ensure the accuracy of the results, we provide a set of relatively complete and reliable detection mechanisms and solutions, and strive to minimize the error.***
