Thread: Firefox not working after upgrading to Ubuntu 9.10

I have recently upgraded to Ubuntu 9.04 to 9.10. Currently the Firefox is not operational. At any time i attempt to start Firefox the window appears with the following msg:

<menupopup id="backForwardMenu"
----^
I tried reinstalling but didn’t help me.

Just aim to reinstalling Firefox as well as xulrunner:

sudo apt-get --reinstall set up of firefox-3.0 xulrunner-1.9
