Likely regression from Bug 1513040 - but it appears it was backed out so the next build should no longer have the crash.

Crashes on https://mobile.twitter.com/

I thought Android got twice-daily updates too? The Play Store tells me there's been no update since 17h ago.

We were able to reproduce this with build from 12-18 and we can confirm that Nightly is no longer crashing when visiting Twitter using the build from 12-19.

Work for me, too, now.
