Untick the option HWDecode in Flash-Aid tweaks to avoid instability. But then you need to disable hardare acceleration in Flash Settings.

That's because Adobe removed the last beta from their site. You need to click "Check Update" in Flash-Aid menu, so it can rfetreive the new ulr. However, since there is no more Beta, the downloaded file will be the same as the stable version from the repos.

Pros: The Flash player at the Youtube site no longer crashes, no longer has difficulties when jumping through the video's time line.
Cons: Wasted too much time trying other solutions.
Keep in mind this is the unsafe solution. Besides, you could simply puth the file inside ~/.mozilla/plugins.
