Firefox is already running, but not responding - Bug?

NOK · 04-14-2008, 04:40 PM

I to am having similar issue. I just installed Fedora 8 on an Dell Optiplex 755 and I get the same error. I can close the program after I try to open it but get the very same error when I try to open FF again.

Same issue even as root.

And do you have a .parentlock in your FF homedirectory?
Can you delete it?

Hi,

hope this might be usefull..

run the following commands...[ofcourse as a user who has firefox problem]

rm -f `find $HOME/.mozilla -name lock`

rm -f `find $HOME/.mozilla -name sessionstore.js`

rm -f `find $HOME/.mozilla -name .parentlock`

I am so excited it worked!

rm -f `find $HOME/.mozilla -name lock`

ok so I know that rm is the remove command could you explain the rest of the command to me so I might learn from this please.

I think it is doing a search in /home that is looking for the lock file and then deletes it.

Unfortunately not. I got "Cannot delete .parentlock - File system is read only".

Why is your filesystem read only? That seems strange to me - last time that happened, my hard disk was failing.

What's the output of the mount command (with no arguments)?

I wish I knew. It surely wasn't until 2 days ago.

none on / type unionfs (rw)
/dev/hda2 on /media/hd3 type ntfs (ro,sync,umask=0022,nls=utf8)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
none on /sys/fs/fuse/connections type fusectl (rw)

But, by the way, although the error message says it is read-only, it isn't. I just typed

mount > file1

and this perfectly created a text file ...

pwc101 · 04-15-2008, 11:28 AM

hmmm... very odd.

Is there any output from this?:

Code:

lsof /path/to/.parentlock

It may be some process is still using the file, preventing it from being deleted. Although, I must say, I'm clutching at straws now...

bash: lsof: command not found

About processes: I searched with ps, and there is nothing firefox related ...

You might need to run lsof as root; it's generally installed on most linux distros.

Try running top as root, then press "u" and type in the username your running firefox as.

Look for firefox, firefox-bin, or anything that says mozilla.

Then press "k" and type in the pid number. If that fails you might be able to logout, but not reboot to kill that users pids.

if all else fails maybe try

ps -aux | grep 'moz*'
or
ps -aux | grep 'fire*'

and see if anything pops up.

No, even as root lsof is not found ... I'll check if I can install it.

Thanks, but no. Not in top, nor found anything by ls ...

The only programs that are running under my id are:
nspluginviewer, artsd, net_applet, startkde, dbus-launch, dbus-daemon, s2u and start_kdeinit ...
