For ages now, whenever I watch a video on YouTube, it usually freezes up or slows down Safari a LOT. It only happens while the video is loading, so usually when it's a long video, Safari will be extremely slow until the video finishes downloading. However, I don't have this problem on Chrome.

Does anyone know what may be causing this? And how I could fix it? Safari is my main web browser, so I'd like to have YouTube functioning properly on it.
 
For Flash-related issues:
  • Find your Flash version and make sure it's the latest version available. Never install or update Flash from a pop-up on a website. Always go to Adobe's site to get Flash or updates.
  • Install ClickToFlash (Safari), Flashblock (Firefox) or FlashBlock (Chrome) to control which Flash content plays on websites.
  • Try using the YouTube HTML5 Video Player to watch YouTube videos, when available. (May impact fullscreen viewing. See link for details.) As far as performance impact, YMMV.

I have the latest version of flash.
I was on trial for HTML... I quit the trial, it seems to be helping. I'll give it a fe days though and see if videos in general are working properly again.

Thank you :)
 
Make sure Safari is running in 32-bit mode. That solved my problem.

On Apple's website, people being signed up for YouTube's HTML5 beta was the culprit. I was never signed up for that.

Find Safar in the Finder, right-click and click "Get Info." Select "Open in 32-bit mode."
