IE

Because... to display a web page a browser needs to read certain elements, hence the opening line of the comic. In web design you have html, cascading style sheets, php, asp, asp.net, and the list goes on. Lets just say that if you ran all of the STANDARD styling elements past any IE version before IE 9 it was garbage. It couldn't even render web pages as well as a mobile phone, quite literally. There is a compliance test you can run on your browser called Acid 3.... 100/100 is normal which means is complies with all standard/basic styling elements. Every IE below 9 scored a 20 or lower. When Microsoft heard this they made an announcement and said the internal framework could score a whopping 32. That was their answer to the hate... That at best it could get a 32... Phone browsers could still score a 100.. This is why Microsoft put so much effort into IE 9. IE 9 can sometimes get a 100/100. Hope this answers your question. Cat picture for the long read.

It is a real answer indeed. Figured I'd try to answer your question.

EDIT: Though I must clarify that Acid 3 does pick out some odds and ends to focus on so it is not entirely accurate. It doesn't test "everything." But as of right now I don't think there is anything that does, so it is as close as we have to a real compliance test.

learn to CTRL+R (thats forcefully refresh and is a stronger function than f5) it deletes all old cache so there would not be any overlaying code. incase something goes wrong on a webpage, try ctrl+r next time, chats and livestreams should work correctly at that point. alwayse dont forget to modify your flash options
