It is possible that your security software (firewall, anti-virus) blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.

Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

Sometimes when FF is closing, not all of it shuts down properly. On Windows, start the Task Manager (Other systems may have different names). Select Applications (list of what user programs are running). If you see Firefox listed, try to shut it down normally. If it does not shut down, then on the Task Manager right click FF, and select End Task. However, if FF still does not shut down, or FF is not listed as running; on the Task Manager, select Processes. Look down the list for Firefox. Right click and select End Task. If this problem keeps coming up, ask for more help.
