firefox process is already running, to create new close the application or reboot

[bvkrock]

hi fres,

i was experiencing this issue whenever firefox crashes abnormally and when i start firefox again it would show " firefox process running, to create new close the application or restart ur system". after googling abt this issue i found that its related to lock thts created with ur profile. to overcome this delete the file named lock or .parent lock in .mozilla/{profile_name}/.parentlock or in .mozilla /firefox/.parentlock located at home folder. you shld do everytime when firefox crashes and pops this message on revoke. bookmarks will not affected.

Hi bvkrock,

To ensure that the process on firefox or mozilla, only has one instance, use man ps from a terminal;

example A

user1@unknown $ man ps

Reformatting page. Please Wait... done

User Commands ps(1)

NAME
ps - report process status

DESCRIPTION
The ps command prints information about active processes.
Without options, ps prints information about processes that
have the same effective user ID and the same controlling
terminal as the invoker. The output contains only the pro-
cess ID, terminal identifier, cumulative execution time, and
the command name. Otherwise, the information that is
displayed is controlled by the options.


I hope this is of help.

HELLO JNIKE,

Hi bvkrock,

Next time the error happens try;

ps -ef | grep -i firefox

&

ps -ef | grep -i mozilla

or even

ps -ef | grep -i lock | more

This may provide better aid to determine, what processes are running under bold text.

I hope this is of help.

Have you tried renaming .mozilla folder? Firefox crashes because of misconfigured conf files or extensions most of the time.

mv ~/.mozilla ~/mozilla.bak

Firefox will generate new .mozilla folder in restart. You can copy bookmarks.html from renamed copy to new one easily.
