RONL  It is certainly no wonder why Apple is not allowing this known buggy plugin to be used for its iPad, etc.

Adobe admits that there has been a known, exploitable, bug in this plug-in for 16 months and though they have released 4 minor updates during that period... they have not fixed it.

Adobe admits that even when it does work that it is way slower than on a PC and yet they have not bothered to even attempt to provide parity.

I use the Adobe Suite professionally so I know that they CAN create great products if they want to... so something is definitely going on here... i.e. mad at Steve Jobs and this is their way of letting him know. I do not see how they can simply be this lazy as Jobs stated.

RONL  Absolutely do NOT install this BETA if you watch Hulu or use Click-to-Flash.

It WILL break them!

BESTLAW  I hate this beta.

Kernel panic's alert message appeared four times yesterday on my Macbook.  
(Version 10.1.51.66)

ILGAZ  It could be adversely effected by Logitech Mouse drivers/applications. Not totally sure but on Mac Mini g4 with them installed, there is a huge crash party... On Quad G5 without them, there is no crash yet.

Of course, if Logitech adds a freaking Input Manager and couple of OSAX things to system, who to blame? Adobe? I don't think so.

SUF  Flash is the Real Player of the 2000's. You can't use the web without it, yet you can't use it with it. It consumes a large chunk of your computers resources unnecessarily and crashes so often it's beyond a joke.

During WWDC '09. Apple made a point that the number one cause of crashes in Safari were caused by web plug-ins, i.e. Flash. It wouldn't be surprising to find all browsers have the same stats.

Rant over, like I say, this is mandatory for the web user, but might I recommend ClickToFlash. It allows you to select which Flash components are allowed to load on any given page, and on YouTube, allows you to access H.264 Quicktime versions instead.

Until HTML5 gets widely implemented, we have to make do with this substandard plug-in.  
(Version 10.1.51.66)

ILGAZ  It is really a beta, when Adobe says beta, it is a beta not something like Google always betas.

Instead of coming here and flaming, you should report whatever crashes in what kind of circumstances to THEM. If you don't have patience or you don't care, you shouldn't be using beta but should be using final/stable version.

QUIIICK  Adobe Flash Player 10.1.51.66 crashes Safari every few minutes when playing flash-movies.

How can Adobe release crap BETAS like that to the public?  
(Version 10.1.51.66)

FRANKO  Yeesh, this beta version crashes faster than Woods' pristine image.

Back to stable version i go.

I do like how Safari isolates the crash instead of quitting altogether.  
(Version 10.1.51.66)

LIBERTYFORALL1776  I hoped for PowerPC G4 performance improvements, but QuickTime still more than blows Flash away in performance/CPU utilization and smoothness. *big sigh* Flash S U X!!!!!!!!
