I have more information on this. Symantec Antivirus causes Firefox to quit very slowly. It eventually quits, but it seems to take several minutes to do so. During this time, the error message "Firefox is already running, but not responding." appears, and Firefox won't start. I switched from Symantec to AVG and the problem went away.

You originally posted in the KB forum, that is where editors discuss articles being written.
If you need an answer or support with a problem may I ask you please to post in the support forum. Use link: /questions/new Sorry for any inconvenience but it will be easier to help you there.
If you are proposing a new article, and have enough information to write about the subject with a verifiable solution to it please expand on the information you have and I will endeavour to help or pass you on to someone else who will be able to do so.
Without knowing anything else about your problem, or attempting to research it, my first suggestion would be that you
ensure that any Anti Virus software is fully updated.
look at whether anything else is, bundled with it ? (There could be a delay in getting bundled applications/binaries to work with new Firefox versions) If so just use the basic AV & any firewall.

I'm moving this back to the Knowledge Base articles forum since it is more about offering solutions and improving the Knowledge Base then asking for Firefox support.
Interactions between certain Internet security software (firewall, anti-virus software) is reported to cause hangs on some systems. You can try to configure your firewall to see if it helps the hang go away.
If you want to improve the existing Firefox hangs or is not responding - How to fix article (instead of proposing a new KB article) you can either make a revision to that article or else add your suggestion in the article's own Discussion forum, by posting a new thread here:
