Windows 8 Metro Browser won’t run any plugins but you probably won’t be missing out on too much thanks to advances in HTML with HTML5.
How The Windows 8 Metro IE10 Browser Would Affect Your Daily Browsing Experience
There are a lot of regular Windows users who are panicking at the thought of losing their capability to use Flash based interfaces on a daily basis on Windows 8. Well, rest assured that if you are running the x86 version, the desktop version of IE will be just like the Internet Explorer you now know — it will accept plugins, have the conventional tabbing option, etc. This is where you will have to go if you want to use sites that require browser plugins.
However, if you are planning to use the Metro browser then you will have to prepare for a life without browser plugins. Which means no Flash because there are very few other browser plugins that a majority of Internet users need.
Not being able to use Flash is actually not as bad as you think. Most of the sites that matter, like YouTube, Vimeo, Beatport, etc. have switch to HTML5. HTML5 is native to your browser and it can do a lot of things that were previously only possible through Flash. This includes sophisticated UI (like YouTube’s video player), games, web apps, etc. And most sites will offer the HTML5 version automatically when the server detects that you are using a browser that does not have Flash but has HTML5 support. You will not have to do a thing. Others have options to switch between the old Flash and the new HTML5 interface as part of the account settings, like on Beatport. You can choose which one is loaded by default after you login.
So unless you are addicted to Flash games, life will go on as normal. And as time passes by, there will more HTML5 games and more games will be ported to HTML5. So you won’t be missing out on gaming either. The bottom line here is that future is plugin-free and that means speedier browser performance everywhere.
