Constant issues with Flash plugin!

For unknown reasons, my Flash plugin stopped working properly about 2 weeks ago. If I start to play a video, it works fine for about 5 seconds, but then it causes the CPU to jump to 110%+, and the video starts to stutter/freeze. It makes content unwatchable.

This happens in both Safari and Firefox. I have both browsers fully updated, and I have Flash 13.0.0.182 installed. I tried reinstalling Flash, but that did nothing. I do not experience any playback issues on my PC.

I'm using a 13 rMBP. Any help would be greatly appreciated as I'm at the end of my rope. Thanks.

 

Nope, the only extension I have installed is ad-block, and it uses the standard block list. Any other ideas on what might be the culprit?

 

The issue actually started with Flash 12, and I only upgraded to 13 about two days ago. So, any other suggestions?

 

I don't doubt that for a moment, but if the content is only available in flash, then...

There has to be a way around this! Apple must know that, however inferior, Flash is still widely used by a vast majority of their customer base. If I have to constantly use my PC, then why bother with a MBP at all?

 

No one is disputing the fact that Apple hates Flash. That said, people still use Flash - I am among them.

I don't care to learn about the politics, I simply want a solution to these playback issues. So, again, I appeal to the MR readership to help me find a solution. I know that several MBP owners do not experience these playback issues, and so I'm confident that a solution can be found.

Any help would be appreciated.
