"Failing at everything" - should be the motto of this company:

Update: fortunately, QL works in Safari as good as under Chrome. Phew... Thanks go to Apple for choosing right technology to build their browser!

Update 2: For some reason my QL settings (sensitivity and overbright bits, possibly others) become messed up each time I start QL in safari. So now I use Palemoon and it is just as good as original chrome.
