Firefox for Android v34 and v35 are crashing immediately on second opening in Samsung KNOX 2.0 and above.

Question

Within a proof of concept situation we figured out that only freshly installed Firefox versions (v34 and v35) are running fine in a Samsung KNOX container. We are running Android 4.4.2 with KNOX 2.1 on a Samsung S5 device. We are using MobileIron 7.5 for provisioning the devices and configuring the container.
The behavior is as follows:
1. Open KNOX container
2. Open Firefox within the container
3. Everything works fine without any problems (expected behavior). Intranet and Internet sites can be opened without any limitations.
4. Close Firefox completely (by multitasking screen)
5. Open Firefox again
6. Firefox crashes without any error message
After setting Firefox to factory settings by deleting all app data (with "System Info for Android" App because the "original" app setting is not available within the container) Firefox behaves like described under 3.
Unfortunately I do only have adb logs because the original Firefox logs can't be exported via USB out of the KNOX container as far as I know. If you have any ideas I would be really thankful for any advice. "about:crashes" can't be used as well because Firefox can't be opened after the first crash and has to be reset (including deleting all logs) by setting it to default.
Outside the KNOX container Firefox works well.
It seems that all KNOX 2.0 and above versions show the same behavior with Firefox which means that Firefox can't be used in a KNOX 2.x container.
We already opened a case at Samsung as well.
