So, I can freeze my firefox (no addons) when going on a specific page (which is not malicious, I guess)
how can I debug what happens ?
(when launched in strace, it freeze on those instructions: http://sprunge.us/gfRE
(no addons enabled)
(it doesn't use a lot of computer ressources)
(using refreshfirefox didn't help)
and I cannot use https://support.mozilla.org/en-US/kb/firefox-crashes-troubleshoot-prevent-and-get-help since about:crashes is not a recognized url.
(which means the version from my distribution doesn't come with the crash reporter)
