and it's EVEN WORSE it's some shitty JavaScript click handler, because nor CTRL-CLICK, nor middleclick, nor rightclick works on them, they just reopen the exact same page :/ one option is to use "Duplicate tab" in Firefox and click manually
I know all too well about those too, including those that don't even let you copy paste or select some text and drag it to a new tab to start a google search... I mean, why make your pages so badly configured?:/
