Browser / Version: Firefox 115.0
Operating System: Windows 10
Tested Another Browser: Yes Chrome

Problem type: Something else
Description: If I access this webpage with the RFP setting enabled on PC or Android, there is a problem where CPU usage soars to close to 100% due to canvas fingerprinting. Please note that this web page is just an example, and when Firefox+RFP is used on numerous web pages on naver.com, a problem often occurs where the CPU soars close to 100%. For reference, naver is the largest portal and search engine in South Korea, and I understand that it has a higher market share than Google. From the perspective of most ordinary Koreans, they can live without Google, but Naver's influence is so great that they cannot live without Naver. However, once RFP is activated, it becomes impossible to use Naver in Firefox, so Korean Firefox users may enjoy insufficient privacy compared to users in other countries. Please keep in mind that Naver is not just an ordinary site, but a site that enjoys a very dominant influence in SK.
