Removes the browser nag that appears in the admin dashboard when using a less-than-current web browser.
Since versions 3.2 of WordPress, when visiting the admin dashboard WordPress will alert you if are currently using an out-of-date version of your particular web browser.
Maybe you're made aware by your own means as to new browser releases and choose to upgrade on your own schedule. Or maybe you don't feel WordPress should be nagging you about your browser. Either way, you can save precious dashboard screen real estate otherwise taken up by a browser update nag.
Heretofore you haven't relied on WordPress to alert you to browser updates. In most cases, the browsers themselves will alert you to updates. And maybe you're tuned into tech news enough to learn of browser release updates. If you need/prefer for WordPress to alert you to browser updates then of course don't use this plugin.
Clicking the "Dismiss" link at the bottom of the browser nag admin dashboard widget only hides the nag for the person clicking it; you cannot otherwise proactively prevent other users from seeing the browser nag. Also, even if the nag is dismissed, WordPress still routinely performs the check, which incurs a network request.
