Firefox Freezes on https://findajob.dwp.gov.uk/

[SergeGardien]

As per subject, every time I open https://findajob.dwp.gov.uk/ (new website) Firefox freezes.
I have tried to turn off the hardware acceleration (https://support.mozilla.org/en-US/kb/tr ... celeration) without success.

This is my system:
Mac OS X 10.11.6
Firefox 60.0.1

Can you please check if you have problems like me?
How can I debug it with the web-console or something else in such situation?

[SergeGardien]

I have found the issue by disabling all the add-ons (problem solved) and then one-by-one.
The problem was caused by Hola (Free VPN).

Glad you solved it. FYI current Mac OS is 10.13.4 - free upgrade.

Thanks, I know, but every time I update it is a pain to solve random issues with my code spread across various programming languages.

Understand. I have some custom things written in Perl, AppleScript and JavaScript. In the latter case I use it for web stuff which I test on the built in Apache web-server on Mac.. The only "pain" is updating the Apache config files with each major release.
