AJAX Spider crashes Firefox

[Stephen McCants]

Hello All,

OWASP ZAP 2.6.0

Firefox 53.0.2 (32-bit)

I'm able to successfully run Firefox configured to use the OWASP ZAP as a proxy and can see my page hits show up in the OWASP ZAP UI.  From the OWASP ZAP UI I can successfully run Active attacks and Spider attacks against my web application and all of this is using form based authentication successfully.  However, if I run the AJAX Spider it runs for a little while and then Firefox crashes without any error messages or error reports.  I get two identical dialogs concerning the crash (see screen shot "firefox_crash.png"):

I looked in %AppData%\Roaming\Mozilla\Firefox\Crash Reports, but there was nothing about the crash there.  

I did find two messages about it in the Event Viewer:

Firefox has no add-ons or extensions.

Any ideas on why this might be crashing?

I'm going to try Chrome or something else in the mean time. 

Thanks!

Hi.

That might have been fixed already (I recall some crash reports in the
geckodriver issue tracker).

I'm not sure if using latest Firefox (Nightly) and geckodriver (0.16.1)
would work (although that's the recommended), since we are still using
Selenium 2.x (one more reason to do the migration to Selenium 3).

Best regards.

Thanks for the suggestion.

I'm not using nightly builds of anything and would rather not if it can be helped.

I switched to Chrome and that seemed to work for me.
