After yesterdays (4/18) rawhide updates, firefox displays an NS_ERROR_FAILURE dialog when starting up and when opening a new window. Doesn't seem to affect anything else. I've included a screen shot of the window. Exact version is firefox-2.0.0.3-4.fc7.i386.

Same exact version works fine here, and nothing changed between -3 and -4 except for the manpage. A few things to try: * Does `rpm -V firefox` turn up any differences? If so, reinstalling the package might help. * Move your profile out of the way: `pkill firefox; mv .mozilla .mozbak; firefox` to see if that fixes things.
Moving my profile aside and starting fresh fixes the problem. Must be related to an extension or something.
Ah. Hopefully you can figure out which one. Closing since we don't ship the extensions.
