>From one duplicate: "However the function (NS_CStringContainerInit) is part of the Mozilla libraries, so this may be a firefox/mozilla problem.
The output from firefox is: /usr/lib/firefox/firefox-bin: symbol lookup error: /usr/lib/totem /libtotem-narrowspace-plugin.so: undefined symbol: NS_CStringContainerInit A couple of objdump runs show that the function needed is provided by /usr/lib/firefox/libxpcom.so. Perhaps there are link problems in how the totem firefox plugins are being built. There is a work around. Run firefox with: LD_PRELOAD=/usr/lib/firefox/libxpcom.so:/usr/lib/firefox/libxpcom_core.so firefox This forces the right libs to be linked in. I am using Feisty of 2007 02 17." Looks like that's one change from the new firefox packaging ** Changed in: firefox (Ubuntu) Importance: Undecided => High Status: Unconfirmed => Confirmed -- Firefox crashes after watching embedded video (undefined symbol: NS_CStringContainerInit) https://launchpad.net/bugs/85112 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
