Please attach about:support and about:memory measurement output as attachments.
When I open the link Firefox' Click2Play asks for running Flash - doesn your issue happen without flash being allowed?

It's not a firefox problem its a problem with this site.

Install Disconnect to protect you from being tracked.

as you can see in the pictures below, there are more than 30 tracker from google, facebook and twitter each
saving over 29s and over 3.4Mb without tracker.

Confirmed on various DxOMark pages, eg.:
http://www.dxomark.com/Cameras/Compare/Side-by-side/Pentax-K-3-versus-Nikon-D7100___914_865

Freeze Firefox 33.0.2 (and previous 32) on Windows 7 x64 with NoScript enabled and plugins disabled or click-to-play.

Could not get about:support or about:memory because of instant freeze.

Hi Sylwester, 

Are you still able to reproduce the issue on latest Firefox versions? E.g. Firefox 43 https://www.mozilla.org/en-US/firefox/new/ and Nightly 46 https://nightly.mozilla.org/.

I also tried but it worked fine for me.

Not reproduced with Firefox 43.0.3
Firefox remains responsive and memory usage is 245MB with just one tab showing the dxo page.

System:
Fedora 23 updated on Jan 8th 2016
Linux 4.2.8-300.fc23.x86_64 #1 SMP Tue Dec 15 16:49:06 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
HP EliteBook 8470p Core i5 3380m, 8GB RAM
