Firefox for Android, Adobe Flash Player, and Samsung KNOX conflict.

more options

Hello. I have a Galaxy Note 3. If I go to youtube.com in Firefox, play a video, and click on fullscreen, Firefox will crash and a notification will come up with title "Prevention information" and description "An application has been forced to stop for an unauthorized attempt to access system...". This notification is generated by "Knox Notification Manager", an app that comes preinstalled.

I know this problem is probably not exactly Firefox's fault, however some of other browsers are able to handle the exact same situation without any problem. Can you fix this problem, or is there a configuration that I can do to fix this?

My system info: Device: Samsung Galaxy Note 3 (T-Mobile) OS: Android 4.3 Adobe Flash Player ver. 11.1.115.81 Firefox for Android ver. 26.0.1

Hi feer56, Thank you for your reply.

It's interesting that there is no entry in about:crash page, and it's even weirder because I can't recreate the crashing situation anymore! I did some changes in settings, maybe it somehow have fixed it...

Anyway, sorry for this. PS: I tried to delete this question but apparently it's not possible.

Hi hamid_ss:

I also have a Galaxy Note 3 and I just played two videos in full screen on youtube.com using Firefox 26 and Firefox 26 didn't crash.

Please reply with a link to a video that crashes and also give us the crashids that feer56 (thanks feer56!) previously requested.

Happy Holidays!
