Just got my rMBP and just switched from Chrome to Safari because of the retina support (not interested in using Chrome Canary builds... yet). I'm still getting use to it, but one of my annoyances so far has been Facebook's refusal to change the title of the page to "xxxxxx messaged you" when someone sends me a message on chat when I open the page from my bookmark. When I type the URL, it works fine but only then. It's a basic annoyance and my friend says he's had no such problems so I'm just seeing if anyone can help me solve it. Not sure how clear I'm being, so if you need more info just let me know.
