Adobe Flash Player 188.8.131.52
Adobe has speedily updated the Mac version of the standalone Flash Player to version 184.108.40.206 to fix a crash that was introduced in Flash Player 13. It turns out that Flash Player 13 was crashing because it was trying to use CPU instructions that were not available on certain Macs produced between 2006 and 2008. If you’ve been affected by this bug, you should update immediately. Or, like many of us, you could uninstall Flash Player, and instead rely on the version of Flash Player bundled inside the Google Chrome Web browser (see “Isolate Adobe Flash by Using Google Chrome,” 8 February 2013). Chrome’s version of Flash doesn’t suffer
from this bug. (Free, 14.9 MB, release notes)
It's notable that I learn of this fix first from TidBITs and not yet from Adobe.
I've taken the good advice and uninstalled Adobe Flash Player from all my browsers (except Chrome, where it's bundled). I'll use Chrome for those occasional instances when I need a Flash Player.
Thank you once again, TidBITs!
