Environment: 
Devices: 
- Lenovo Yoga Tablet 2 (Android 4.4.2);
- Asus Transformer Pad (Android 4.2.1);
Build: Beta 52.0b4 build 1

Steps to reproduce:
1. Open Fennec;
2. Go to Menu -> Settings -> Search;
3. Choose a new search engine (e.g. Twitter);
4. Go to Beta Search Widget and search for something (e.g: abba);
5. Tap on Recent soft button of the device and close the Search widget from task manager;
6. Tap on browser.

Expected result:
Browser opens displaying the last accessed page: in this case the Search tab from the Settings.

Actual result:
Browser crashes.

Notes:
There were no crash reports displayed in about:crashes, so I manually tried to find them by accessing https://crash-stats.mozilla.com/topcrashers/?product=FennecAndroid&version=52.0b4&days=7&process_type=any
This is one of the crash reports: https://crash-stats.mozilla.com/report/index/b59b57ee-901e-4bcc-a8e0-0804f2170207
On Asus ZenPad 8 (Android 6.0.1) and Nexus 6 (Android 7.0) this is not reproducible.
Please see the Screencast attached.
Nightly, Aurora and Release versions have different behavior while following this steps to reproduce, for which I'll submit a new bug report.

The Search Activity is no more, but I'm not sure if we could somehow still run into this crash.
