Starting with today's Nightly Whatsapp Web crashes the tab on loading. Mozregress is pointing to https://bugzilla.mozilla.org/show_bug.cgi?id=1440144 Let retained-dl ride the trains It seems strange that it would suddenly cause a crash when the retained layers has been on Nightly builds for awhile now ? Something wrong with patch perhaps causing crashes on Nightly ? Tested on Win10 x64 Today's Nightly cset: https://hg.mozilla.org/mozilla-central/rev/ea3da643422c58d65335f1778dd6c89c09911585 https://crash-stats.mozilla.com/report/index/2bd40b2c-f93e-4bef-9ce1-79a2a0180222

Maybe a dup of https://bugzilla.mozilla.org/show_bug.cgi?id=1436904

Marking as Dupe - backout of bug 1436904 and testing with the latest Tinderbox build on m-c with the backout fixed the crash at Whatsapp Web
