Actionscript 3 :: TextFormat And TextFields Display Different Outside Of FlashPlayer

I have been using TextFields like this to render text for a game. I've been developing in FlashDevelop, so the SWF is compiled using the Flex compiler.

My problem is that this text is not displayed with the appropriate formatting when I view it inside the browser as opposed to a flashplayer (which looks fine). Different screen resolutions tend to vary in how they distort text in the browser.

var welcomeText:TextField = new TextField();
//formatText creates a TextFormat object, sets those values into TextFormat
//then returns after doing TextField.defaultTextFormat = TextFormatObj;
