Highlander

When you click a Link to an url that`s already open in another tab then you`ll switch to that tab instead of actually opening the link. However, some sites using heavy JavaScript may not work correctly with this, so the extension also offers a whitelist of urls not affected and the ability to disable the extension at the click of a button. The whitelist supports wildcards, * is the wildcard character and will be interpreted as any character zero or more times
