Steps to reproduce:
1. Launch Firefox and tap the private browsing button

3. Tap the Settings button
4. Tap Done button

Actual results:
- The Done button has no functionality

Expected results:
- The Done button should have proper functionality

Note:
- Using the above steps to reproduce the application entered in an unresponsive state and crashed.

I'm not able to reproduce this. Can you attach a crash log? Which device are you using?

On my iPhone 6 (4.0 build 11)

=> Launched Firefox
=> Tapped the tab button, tapped the private toggle
=> Tapped Learn More
=> Tapped the tab button, tapped Settings
=> Tapped Done

Tapping Done works for me.

Do you have any missing steps here?

After tapping the "Learn more" button(visible in private browsing) and before the page is opened there is a shot time in which the user can still tap on the Settings button while in tabs tray. When tapping on the settings button while the page is loading the done button will not be functional. Please see a video of the issue for more information: https://www.youtube.com/watch?v=Xung5ixGZUc.
