1248270 - Continual crashes while using New York Community Bank web site : mynycb.com

Status: RESOLVED INVALID

(Core :: Hardware Abstraction Layer (HAL), defect)

Description

[Michael Sinz]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.11; rv:44.0) Gecko/20100101 Firefox/44.0
Build ID: 20160210153822

Steps to reproduce:

Was navigating the https://onlinebanking.mynycb.com site for my mortgage.  Just clicking around in the various things (history, balance, payment, etc) will cause Firefox to crash in a rather nasty manner.  It happened 8 times for me today.  I finally switched to using Safari to complete what I needed to do - it worked without problems.

Note that I have flash set to not run except when clicked on and other plugins mostly disabled.

I can not give you my account information to do the browsing and there is no easy way to get to this that I can see without a login.


Actual results:

Sudden crashes in Firefox


Expected results:

No crash - be able to actually use the we site.

I am somewhat concerned about the crashes as they could be an indication of a potential data leak or remote execution.  In a way, I am glad it crashed rather than doing something bad but it would be better to not have the problem in the first place.

The crashes appear to be in a GeForce graphics driver. Does disabling hardware acceleration help (in Preferences > Advanced). You might also see if there are updated drivers for your graphics card.

If you note, this is on a MacBookPro Retina - no 3rd party drivers.  I will try turning off the discrete graphics chip.

Comment 5

[Michael Sinz]

Turning off the hardware acceleration feature in Firefox seemed to have made things work.

Turning off the discrete graphics chip also seemed to have made things work.

In both cases, it was faster than when I turned on hardware acceleration again.  Something strange about the fact that acceleration is actually a deceleration.  (Don't have measurements as I was trying to get/prove a repro)

Will try to recreate next with everything back to default.

PS - While trying to reproduce the crashes, I noticed some rendering glitches as I switched views on the web site.  Whole parts of the page did not render until I moved my mouse over the now hidden links (and thus they displayed/highlighted)

This did not happen with acceleration off.  Almost seems like some race in the system (either in Apple's GPU switching code or in Firefox's hardware acceleration code)

Comment 7

[Michael Sinz]

The crash happened again after having written the above.  It happened after logging into the account and trying to go to the specific sub account page there (I only have one account there so it could have gone there directly but their web site does not do that)

The crash was:  bp-4bfc0827-33d7-46a8-bae6-8400d2160214

Closing as INVALID since it appeared to be a GPU driver bug and besides it didn't belong to the HAL component.
