when surfing the internet, if gnome dark theme enabled, the text displayed by firefox may have the improper colors with no contrast to the background. such as, http://proftpd.org/docs/howto/NAT.html, or just www.bing.com, If the gnome theme set to white, nothing wrong. it should be a issue with upstream source, but maybe ,it's related to the use settings. Reproducible: Always

I find that with USE 'force-gtk2' enabled, this issue is solved, but it's still a problem for gtk3 support.
If you feel I have closed your bug and it is still a current issue, please reopen and update it completely. We will not work bugs that have no ebuild in tree any longer or can not be reproduced with a current system. Thank You for your support and understanding The Mozilla Team
