I've followed https://github.com/lhl/chrome-ssb-osx to setup a SSB instance of Chrome for Gmail. It works amazingly well, except that links within email open up in a new window in my SSB instance of Chrome, leading to all sorts of confusion later one. Anyone know how I can lock chrome to a single domain? Ideally, attempts to open URLs outside this domain will open in my "default" Chrome instance. But just blocking them is ok.
