◆ The procedure to make Firefox the default application for Windows is complicated.
According to Mozilla, Firefox was developed with a focus on protecting user privacy. However, in Windows, the procedure for setting a web browser other than 'Edge' as the 'default app' iscomplicated, and the procedure for setting Firefox as the default app is more complicated than before. Mozilla countered Firefox by adding 'a function to bypass Windows interference and set it as the default app ' and 'a function to prevent Edge from forcibly starting with some links'. , Microsoft has also made changes to circumvent Mozilla's counter-operations, making it harder than ever to continue using browsers other than Edge.

◆ Cannot provide a browser that uses Gecko for iOS
Firefox uses Gecko as its rendering engine, but Apple does not allow web browsers distributed on the App Store to use any rendering engine other than WebKit . For this reason, the iOS version of Firefox uses WebKit instead of Gecko. Mozilla claims that Firefox for iOS is forced to adopt WebKit, so it cannot provide iOS users with features such as the 'cookie management system that protects user privacy' that Firefox has.
