I am running CENTOS 7 with all updates, so FIREFOX is version 38.5.0

Since last update I can't open a browser window from an application, when I am already running firefox. This worked before without any problems.

Error message: Firefox is already running, but is not responding. To open a new window, you must firest close the existing Firefox process, or restart your system.

You can use the -no-remote command line switch instead of the environment variable if you need to start another instance with a separate profile.

I had set MOZ_NO_REMOTE=1, because somtimes I connect via x2go. After removing it, everthing was fine.
