1567189 - Crash in [@ java.lang.NullPointerException: at org.mozilla.gecko.BrowserApp.showHomePagerWithAnimator(BrowserApp.java)]

Status: RESOLVED INCOMPLETE

(Firefox for Android Graveyard :: General, defect, P5)

Description

[Marcia Knous [:marcia]]

This bug is for crash report bp-1e1a1506-611e-4ce2-9fa1-e1cf10190718.

This seems to be a regression in Fennec 68 that started back when Fennec was in 68 nightly: https://bit.ly/2LYUxJC. It has become a bit more visible since we went to release and was seen during nightly crash triage.

One comment: just started Firefox from the search bar widget on my android OnePlus homepage

Huawei ANE-LX1 is the top crashing device, followed by Samsung SM-G960U.

Although this isn't terribly high volume, it would be interesting to understand what we regressed here.

Crash rate is too low to address.
