firefox not closing properly; Ubuntu 10.10

[scott]

I close firefox, try to reopen it and a popup says firefox is already running. I have to pgrep the pid and kill it.

Running firefox from a terminal I get :
** (<unknown>:3485): DEBUG: NP_Initialize

It appears in the "bool KillProcess(ProcessHandle process_id, int exit_code, bool wait)" function in process_util_posix.cc

// Attempts to kill the process identified by the given process
// entry structure. Ignores specified exit_code; posix can't force that.
// Returns true if this is successful, false otherwise.

and the error in process_watcher_sigchild.cc is a simple

line 162: LOG(ERROR)<< "Failed to deliver SIGKILL to "<< process_<< "!"
            << "("<< errno<< ")

Another time I did a memsat | grep firefox and got this after closing the firefox window:

It actually appears like it has to do with 'plugin-container'. Should I report it there, also?
