1397909 - This page causes Firefox to completely hang for several minutes or even cause the phone to restart

Status: RESOLVED INCOMPLETE

(Firefox for Android Graveyard :: General, defect, P2)

Description

[Kostas]

The page is: 
https://brendaneich.com/2015/06/from-asm-js-to-webassembly/


Trying to load it in a clean FF 55.0.2 profile (no addons) in Android 7.1.2 (my phone is Nexus 5x)
it consistently causes the phone to: 
- either completely hang for several minutes (during the hang the screen becomes dim, I can' even reveal the notifications, or make the screen off/on via pressing the Power button), it has happened 3 times in a row, consistently. After 1-2 minutes, the screen becomes black and stays black, and a few more minutes later I can use the phone again by pressing the Power button to make the screen on again, and Firefox is not running anymore.
- or make the phone reboot (after hanging for several minutes).


In both cases there's no crash report in about:crashes, never.

The phone doesn't have malware, nor has any other issue - this only happened with this specific page.


I also tried loading the main page, https://brendaneich.com :
the phone seems to hang momentarily (for a few seconds) while the progress bar is about its 3/4, but then completes ok.


For reference, in Chrome 60 for Android it loads ok every time.


PS. I'm aware who Brendan Eich is, nevertheless, as I said, this issue happens consistently.

Hi, 

Was able to reproduce this issue on a Samsung Galaxy S6 EDGE (Android 7.0) on the latest beta (56.0b11) and latest Nightly (57.0a1) by following the repro stept mentioned with a little modification to trigger the crash each time (try scrolling the page while the page is loading). For the crash, I can confirm that no crash-logs were generated but I've attached a .txt file containing the log.
Could not reproduce on a Samsung Galaxy S8 (Android 7.0) by following the repro steps.

This is OOM, but not sure why. Overzealous layerization is usually the culprit.
