When visiting some Chinese commercial websites with firefox, I often encounter errors as shown in the screenshot. But other browers like Chrome have no such problem. I know this is because the websites didn't obey the protocol, but does anybody know how to resolve this problem? Some example webpages are listed below: https://www.jianshu.com/p/1e09fbcfe21b https://m.bilibili.com/video/av9833732 Any link in this page: https://m.huxiu.com/moment/1721.html I know the reason: more and more Chinese business websites are trying forcing users to install and visit their websites via their own apps rather than universal brower, so that they can raise their visiting flow, and then they can attract more investors.
