Don't forget, the code for Firefox dates back to the late 90s and Firefox can only handle 1990s kinds of webpages, at least for my many years using Firefox.
That's just not true. It is quite the opposite the case. MS-IE is the browser how has the most difficulties in handling modern CSS/HTML-concepts:

BTW: Playing a flash has primary nothing to do with the browser itself. For this purpose exist so-called plugins: Extrenal programs called by the browser to display such contents.
BTW 2: When the mozilla-group took over the sources from Netscape they rewrote almost the entire code. I would be surprised if in the actual Firefox-code would be still a single line from the 1990's.
