Adobe Flash Player crashes whenever accessing settings

[UnoriginalUsername]

• Your operating system & version: Windows 8.1
• Your web browser(s) & version:  Mozilla Firefox 33.1.1
• Your Flash Player version:  Shockwave Flash 15.0.0.223
• Explain your problem in step-by-step detail if possible:  When accessing the settings of a flash-player window, by right-clicking on the window and selecting "settings," or by simply opening up a webpage that automatically requests access to webcam settings, adobe flash-player will invariably crash.  Sometimes, this crash does not happen immediately and I'm allowed to access some of the settings, and other times I'm not.   This seems to be coorelated with adobe flash player accesssing my webcam.  
• A direct link to a page that demonstrates the problem:  An example of a page that allow me to access some of the settings before crashing:  The Pituitary Gland: Anatomy, Circulation, Hormones, and More! - YouTube An example of a page that crashes upon accessing the settings at all Twitch and an example of a page that crashes simply upon loading due to requesting access to settings Omegle: Talk to strangers!

It doesn't seem to be a problem in chrome...but I don't want to use chrome unless I absolutely have to.

Does the crashing occur immediately, or after the dialog has been sitting open for a while?

which dialogue are you referring to?  The crash occurs before the "stop script" comes up on twitch, and the instant that you tab to the webcam settings on youtube.  For omegle, only the video portion crashes (the rest of the app runs perfectly) but it also crashes any other running instance of adobe.

Does that help at all or do you need more information?

Hello?

Firefox will hang if you try to open the right-click context menu on Flash Player in Windows 8.1.  It's a known issue.  It's unclear at the moment whether its our bug or Mozilla's.  The bug is assigned to a developer for investigation in the Flash Player 16 timeframe.  Firefox is killing the Flash process, which causes the crashed plug-in dialog to be displayed, but it's really a hang, and the player is terminated safely.

In the meantime, you'll need to use Chrome or Internet Explorer as workaround.
