If you have been getting “Missing plug-in” error while accessing Flash content on some websites, this addon solves your problem.
Technical explanation of the error:
Google Chrome has a bug in which it does not render flash content when the “embed” tag doesn’t contain attribute type=”application/x-shockwave-flash”. This error is common on Linux more than on Windows or Mac. This extension will use jQuery to add the needed attribute and reload the content, thus Chrome can display it.
