I had the same issue. When I ran strace on it, it looked like it was timing out waiting for a socket it had opened to talk to pulse audio. I had pulse issues on my ubuntu machine.
Anyways, I found another suggestion about disabling esound in pulseaudio. That enabled pulseaudio to start, and then all the FF issues disappeared. In my case, I got things working by commenting out these lines in /etc/pulse/default.pa: ## .ifexists module-esound-protocol-unix.so ## load-module module-esound-protocol-unix ## .endif load-module module-native-protocol-unix My suggestion to the FF team would be to "remember" that opening the audio subsystem failed and not try to do it again. That would make the first right-click or audio-linked action fail, but not subsequent attempts. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/874260 Title: Firefox freezes when I right click or try to open up bookmarks.
