[gentoo-user] Firefox crashes on some www-pages on a newer Gentoo system

[gevisz]

I have two Gentoo systems on the same AMD Athlon 64 X2 computer.

The old one was installed in July 2013 with
default/linux/amd64/13.0/desktop/gnome (stable)
profile and was updated till the middle of
July 2017. Initially it hosted Gnome2
but later I have switched to XFCE4.

The new one was installed in January-February 2018
with default/linux/amd64/17.0/desktop (stable)
profile and was last updated yesterday. From the
very beginning it hosted no DE, only Awesome WM
and dbus.

The home directory is the same and still remembers
Ubuntu 6.04 installation in 2006.

On the old system, I had the problem that chromium
very often (but not always!) asked me for some
(keyring?) password when I opened a new www-page.

Recompilation of it with different user flags did not help.

I thought that that was because of the gnome-keyring,
consolekit or policykit packages but without any proof.

So, while installing the new Gentoo system, I decided
to avoid installing any package that needs gnome-keyring,
consolekit or policykit packages.

I have also set -pam -consolekit and -policykit in my
/etc/portage/make.conf

Chromium indeed never asked me for the mentioned
above password on the new Gentoo system.

But I get another problem on the new Gentoo system:
Firefox and Qupzilla both crash on some (login) www-pages.

Namely, Firefox shows the "Gah. Your tab just crashed"
when I try to log into my Yahoo e-mail account.

This happens only after entering login and password,
so not good enough to reproduce.

However, it shows the same message just after staying
about 3-5 seconds on the following internet banking
login page: https://www.privat24.ua/#login
No login or password needed. :)

The last error messages sent to terminal by FF while I
try to open the last www-page are the following:

As to the Qupzilla, it crashes on the page https://www.privat24.ua/#login
completely, with the following messages sent to terminal:

The mentioned above crashlog file contains only the following:

#2: [0x7f3a3c18d2c9]

Strange enough, but on the old Gentoo system Firefox does not crash on
the said www-pages.

I initially thought that all that because
I have set -consolekit and -policykit use
flags in my /etc/portage/make.conf on my
new Gentoo system but unsetting them
does not lead to any recompilation while running
# emerge --update --deep --with-bdeps=y --newuse --backtrack=100 --ask world

Any thoughts about this?
