so as cross-browser compatibility basically means I am making a project which I am testing on Google Chrome and there is other browser like Brave or like your Mozilla where the application is not running so basically there must be a course issue cross-origin issue or something which has a different name in that browser then in Chrome basically but right now every browser is following a paradigm so that there isn't issue of cross-browser like like cross-browser issue there's none according to me there's none right now because they are all following a following of specific rules and paradigms in that
