Same problem on Ubuntu 12.04 with KDE installed. I used rekonq to find this page, and then downgraded to v45 as follows:
1. Google for 'firefox 45.0.2 deb 0ubuntu0.12.04', this yields a pointer to the original Firefox 12.04 binaries for Ubuntu 12.04 (the ones in http://security.ubuntu.com/ubuntu/pool/main/f/firefox/ don't work in older Ubuntu releases such as 12.04). The result is https://launchpad.net/~ubuntu-mozilla-security/+archive/ubuntu/ppa/+build/9572863 . 2. Download the necessary binary packages from there. 3. # dpkg --remove --force-all firefox firefox-locale-de firefox-locale-en # dpkg -i --force-all firefox_45.0.2+build1-0ubuntu0.12.04.1_amd64.deb firefox-locale-de_45.0.2+build1-0ubuntu0.12.04.1_amd64.deb firefox-locale-en_45.0.2+build1-0ubuntu0.12.04.1_amd64.deb # apt-mark hold firefox firefox-locale-de firefox-locale-en -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1575781 Title: Firefox 46 crashes on Ubuntu 12.04 (precise) with Oxygen-GTK3 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1575781/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
