I don't get a re-direct in Firefox 41.0.2 in Yosemite 10.10.5, but the WARNING still pops after/with each page access with the latest update (for which I don't particularly care) . . . subtle hint that we should subscribe to avert ads . . . ?Safari, 9.1 on iPad Air 2
I keep getting this weird flash warning, which is odd so must be some of the ads, because after twice clicking Ok it tries to redirect me to that site on the second screenshot.
