User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.11; rv:51.0) Gecko/20100101 Firefox/51.0
Build ID: 20170125094131

Steps to reproduce:

Go to www.business.govt.nz/compliance-matters when NVDA is on.


Actual results:

Firefox stops responding.


Expected results:

Should have been able to use the site.
OS: Unspecified → Windows
NVDA : https://www.nvaccess.org/

Also, the compliance matters app is based on React.
Do you have a crash report (bp-...) in the page about:crashes? If yes, could you paste the link.
Flags: needinfo?(alexandre.saelens)
The www.business.govt.nz/compliance-matters redirect to https://www.business.govt.nz/Security/login?BackURL=%2Fcompliance-matters and says 403 Forbidden.

Sorry no crash report as for some reason Firefox does not crash. Just hangs for ever.(In reply to YF (Yang) from comment #3)

Unfortunately they have restricted the access for now, I'll keep you posted as to when it's going live again.

Thank you both for looking into it.
Marking this as Resolved - Incomplete due to the fact that the site is restricted for now and cannot test this.

Feel free to reopen this when you find other steps to reproduce the issue or if the webpage becomes available again and you can still reproduce it.

Thank you.
Status: UNCONFIRMED → RESOLVED
Closed: 7 years ago
Resolution: --- → INCOMPLETE
https://www.business.govt.nz/compliance-matters is now public and anybody should be able to access it without logging in.
With the new version of Firefox, the app loads without crashing the browser. However, the browser crashes when trying to interact with a drop down.
Still no crash report...

I am able to reproduce this with NVDA and loading pages on Bugzilla.

https://crash-stats.mozilla.com/report/index/8cf7a603-e5e8-4fde-8486-bd0782170313


Steps to Reproduce:
1. Visit https://bugzilla.mozilla.org/page.cgi?id=productdashboard.html

Expected Result:
Page should respond and open

Actual Result:
Page stops responding and Firefox crashes. (See Crash IDs)
Summary: Screen reader NVDA + react app make firefox crash → Screen reader NVDA causes Firefox to Crash
Blocks: 1258839
Status: UNCONFIRMED → NEW
Ever confirmed: true
Was able to reproduce a few more crash IDs on a different low-end computer.

These were with e10s on. 

Unfortunately, this is a blocker from being able to test further with the NVDA screenreader as any website with the screenreader on begins a crash.
