FIrefox, Google-Chrome and Chromium don't work anymore

I'm running Firefox 26 on OpenSUSE 13.1 64bits.

I got problem in Firefox 26 to use IBM Lotus iNotes and the recommendation is to revert to Firefox 24.2 ESR. I tried to do this, but it didn't work.
Now i uninstall all Firefox and installed the latest version (26) again. Now Firefox won't load any web-page. It just saying "Connecting..." but nothing happens. No timeout nor error-mesg.

If i run Firefox in terminal, i get this message; (process:3072): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed
I also backed up the profile og recreated a new profil. I suspect that the version 24.2 ESR did some change to files, but i uninstalled everything, rebooted and installed new. Still it doesn't work :-(

So i then downloaded and installed Chromium. It doesn't start and it give error i terminal;
[1213/135331:ERROR:nss_util.cc(686)] Failed to load NSS libraries.
[1:1:1213/135331:ERROR:nss_util.cc(686)] Failed to load NSS libraries.

Then i downloaded Google-Chrome and installed it and i get excact same error:
[1213/135513:ERROR:nss_util.cc(686)] Failed to load NSS libraries.
[1:1:1213/135513:ERROR:nss_util.cc(686)] Failed to load NSS libraries.

The only web-browser that still works is Opera :-(
