Scott Reilley who also goes by Coffee2Code is continuing his trend of releasing small but useful plugins for niche audiences. This time, he has released a plugin called No Browser Nag that removes the Outdated Browser nag found within newer versions of WordPress.
While it’s a bit foolish to condone the use of outdated browsers, sometimes users don’t have a choice. At least with this plugin, that user group will be able to remove the constant nag and allow WordPress to get off their backs about a situation they may not be able to control. However, if possible, you should upgrade to the newest versions of your browser of choice as they often contain important security updates, performance improvements, etc.
The problem with Browse Crappy is that it moans even if you’re on the latest version of your browser of choice for your OS.
e.g. IE8 is the latest browser for Windows XP
It also moans at you if you are using IE9 under certain circumstances.
