1246829 - Closing many tabs quickly can break page loading

Status: RESOLVED INCOMPLETE

(Firefox for Android Graveyard :: General, defect)

Description

[Ben Kelly [:bkelly, not reviewing]]

STR;

1) Load twitter in many tabs.  (I just did 6 using my home screen bookmark on FF44.)
2) Go to tab view and notice that many are not loaded since FF oomed while loading such a large site many times.
3) Swipe right on all the tabs as fast as you can from the bottom to the top.
4) Try to launch twitter from the history.

Expected:

Twitter loads.

Actual:

Loading bar moves, but site does not render and url bar does not show twitter.

Definitely intermittent.  Took me a few tries to reproduce this time.  Screenshot of the loading bar and no other rendering.

This sounds like something in our tab state is getting out of whack. I'm worried that this will be a difficult issue to debug and fix.

Ben, can you try to capture a logcat the next time you see this happen? I'm interested to see if there are any JS errors causing gecko bustage.

I'm sorry, I haven't seen this since the open-same-tab-from-homescreen functionality was fixed.
