Available immediately is a new super-simple WordPress plugin, Logout Clear Cookies, which does just what it’s name says — when you log out of your WordPress site, it will clear all the cookies that WordPress has set in your browser. Because leaving a trail of cookies behind you is bad!
The plugin is actually just one line of code (more or less), so it’s super easy to install and use (and to uninstall). There aren’t any options or configuration screens. I’ve been running it for the past couple of years without any problems, so you shouldn’t have any, either. But if you do, just let me know!
If you’re still wondering, why would I want this? Well, do you like it when you visit a website that sets cookies in your browser, but never clears them when you log out? If that’s not enough of an explanation, please see the plugin page.
