I forgot to confirm that setting dom.ipc.plugins.enabled.libflashplayer.so to false resolved the problem for me, but (obviously) only for pages that have flash contents.
I've developed a dummy HTML page with two links. The first one brings a plain HTML page (no JavaScript, no Java, no Flash) on a popup window and the second one brings a JavaScript alert window. When I click the first link, firefox freezes. When I click the second link, the alert window appears without any problem. I've made this test to make sure the problem is only when you need to bring a popup window, and not when you need to execute JavaScript code (because to bring a popup window you need to execute JavaScript code) -- Flash, Java, etc. does not work with out of process plugins and causes Firefox to become unresponsive https://bugs.launchpad.net/bugs/513887 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
