Crash in Firefox 29.0.1 + flash 13(or 11.7) plugin + dell venue 8 pro + windows 8.1 #8

hello,

Currently I am testing my web application in the dell venue 8 pro tablet.
When I try to open my scriptCam loaded page in firefox it shows Flash plugin crashed like this image : http://s.techairlines.com/wp-content/uploads/2010/06/Adobe-Flash-Crash.jpg.

Please Note : youtube and all other flash base sites work proper, Even ScriptCam works proper in IE 11 👍 and chrome 👍 but not in Firefox 👎 .
Edit:
Also test with Flash Plugin 11.7, but not working 👎
