This way alll you have to do is download, install and use an alternative web browser, instead of upgrading your entire Mac OS. My internet browsers (Safari, Firefox, Chrome - tried everyone) can't show a frame with streamed video. The ESR version 45 of Mozilla Firefox is still completely secure. I'm working on a iMac 12.1 and i'm really happy to have my favourite Snow Leopard 10.6.8 OS, althought there are several problems with Adobe Flash Player. Mozilla will issues ESR (security) updates to OS X10.6-10.8 for the version 45 of Firefox, but will not get ANY new web browser functionality feature updates. Mozilla will keep issuing security updates for Firefox in the form of their Firefox ESR web browser (Extended Security Release web browser program, vers. OmniWeb runs on PowerPC and Intel Macs running OS X 10.4.8 Tiger or later, and the development version is adding OS X 10.10 Yosemite support. If you need a more secure and compatible web browser that'll use the current Adobe Flash Player, switch to using Mozilla Firefox's web browser version for OS X 10.6.8- 10.8.5 here. Of the browsers that claim to still be in development for the Mac, it has the oldest most recent version. To our surprise there was nothing out there. If you are still using the version of Safari for OS X 10.6.8 Snow Leopard, that Safari version is very old, hopelessly out of date and no longer secure and you should stop using it ASAP, if not sooner! There was a separate track for each Mac/Windows/Linux and several manual and error-prone steps along the way.
Here's a much easier option for you until next Spring.
