Bug with www.digitheque-belin.fr url

[lerevecbeau]

When I'm go to www.digitheque-belin.fr web site and I add "www.digitheque-belin.fr" in white list, firefox crashes by consuming 100 % of CPU.
When I disable NoScript, there's no more problem.

I'm using firefox 45.3.0 x64 under mageia linux.

A weird site indeed.

In SeaMonkey, new Profile, I got nothing more then the "spinner".
Otherwise nothing ever loaded (displayed).
There was some non-stop https: error in Error Console.

In FF, nothing Allowed, got the spinner.
Allowed digitheque-belin.fr, the page displayed, & FF was eating CPU.
Stopped (from the FF warning dialog) the "page", then went to Options | Advanced & entered digitheque-belin.fr into 'Never force secure (HTTPS)'. Reloaded the page & all looked OK.

After that, not sure just what I saw?
Spinners. Sometimes a page load, most times not.
Plenty of CPOW warnings in Error Console.
+gutenberg-technology.com, not sure where that crawled out from?
fonts-gstatic.com (I think it was).
Other (including angular.min.js) Errors from the digitheque-belin.fr end.

Anyhow, it appears, that if you first Allow gutenberg-technology.com (adding it to your whitelist), then Allowing (temporarily or otherwise) digitheque-belin.fr, works.
