The problem looks same as bug 1044400.
(In reply to [:Aleksej] from comment #1) > The problem looks same as bug 1044400. Yes, but note that the summary of bug 1044400 doesn't say that FF is unresponsive, which is the main problem.
[bugday-20140818] Replicated this on firefox-34.0a1.en-US.linux-x86_64 (17-Aug-2014). The browser did freeze on the third try but after the page was loaded, and CPUs took significant amount of load. OS: Ubuntu 14.04 Hardware: x86_64

http://www.cinemapassion.com/lesaffiches/ is inaccessible do you have another testcase example??
Indeed, the web page no longer exists (I've looked at the site whether the page moved somewhere else, but this doesn't seem to be the case). I don't have any other testcase.
Thanks for checking
