**Note: this appears to be repaired in the latest release of the player – thanks to everyone who helped get the word out and tested!

Yesterday I was testing some Flash content after installing Firefox 3. I noticed that some of my movie clips which had events assigned to them were not acting like buttons. I also noticed that if I went above the normal hit area of the button that I could catch a pixel or two of the button. I thought that I had screwed something up in my code or layer structure somewhere along the line.

Later in the day a friend asked me if I had been experiencing any problems with Firefox 3 and Flash. “YES!” I said. Basically I have confirmed a bug which exists, at least on a Mac, involving Firefox 3 and Flash Player 10b. I looked up the bug in Bugzilla and there are some semi-related items (from old builds). I have documented this in a screen record which you can view here:

Get the Flash Player to see this player.

For the record here are my system specs:
Mac Pro with Leopard (10.5.3)
Flash Player 10b
Firefox 3

• This was confirmed on a MacBook Pro with the same.
• We checked a MacBook with Leopard and Flash Player 9 and the problem did not exist.
• It did not exist on my machine under FF2 and FP10.
• PC with XP, FF3 and FP10 the bug was not present.

If anyone has additional insight into this that would be great! Looks like it is mainly a Flash Player 10b issue though red flags were raised based on the previous bug related to Flash and Firefox 3.
