I couldn't logout of WordPress until I excluded all WP sites from being used: http://*.wordpress.com/*. There are a bunch of link-changing extensions and many more websites that use redirects and javascript to do certain actions. If you think WP is a very common one, please include it in the default exclusion list.

Perfect! There is an annoying "off site warning" on a certain forum I visit, and so I removed the * for included sites, and just added that forum. Works like a charm, thanks!

All scripts that unconditionally change links like this, presuming it knows the semantics of any part of the URLs without being hand coded for every site of the web runs the risk of breaking things. http://www.userscripts.org/scripts/show/1897 does the same things, but requires you to click a "unzip <number>" icon that pops up on pages with links containing embedded URLs.</number>

Not bad, but it broke a proxy site I was using.
