why is Firefox getting a request to close Firefox to open a link from Facebook and from Thunderbird and Betterbird

Right click on any link in Facebook asks for me to shutdown Firefox to open a new page. What is causing this? The same thing happens if I am in Thunderbird or Betterbird. It's OK to open a new tab but not restart Firefox.

You may need to delete a lock file. See this article.

Are you starting Firefox with the -no-remote command-line switch ?

Yes, Profile was read only. Wish I knew how that happened. I'll let you know if it still happens.
