Yes, this problem exists in old Firefox too. My desktop was not updated 
for more than 6 month, so I have

SeaMonkey 2.32:
Mozilla/5.0 (X11; FreeBSD amd64; rv:35.0) Gecko/20100101 Firefox/35.0 
SeaMonkey/2.32 Lightning/3.7

Firefox 35:
Mozilla/5.0 (X11; FreeBSD amd64; rv:35.0) Gecko/20100101 Firefox/35.0

Both crashed on mapy.cz and seznam.cz

I tried newer version in freshly installed VirtualBox VM with Firefox 40 
and 41. Results are the same.

I will try debug version in the next few days as time permits.

Thank you for your help.
