Or, as I found on a BBC news page earlier today (and reported via feedback), my middle mouse button on link to open in new tab wasn't -- the page was opening in the present tab.
Don't break user controls.
Seriously. Fucking. Annoying.
The tendency of sites to also force all links to open in a new tab is similarly annoying. I've got the means to choose. Leave it to me.
Another argument for disabling JS pretty much everywhere.
