Hi,

We are 3 using RDProtocol to a remote machine. I just installed Firefox and what a surprise when everyone want to use Firefox in the same time, a problem happens : Just one can use it, while the others get this message: "Firefox is already running....Close the process" Isn't Firefox multi-process ? We tried some other browsers and oddly the problems does NOT happen. For my mind I'd like to use Firefox mainly for HTML developing and firebug. Is here someone able to help me?

Config: Windows 2003 server Firefox 13.0.1

Thank in advance

Does the error occur when everyone logs in as the same Windows user, or when they log in as separate Windows users, or both?

To run isolated sessions of Firefox, you need to make a few configuration changes. Please see cor-el's solution in this thread: https://support.mozilla.org/en-US/questions/925594#answer-327043

The multi user is a solution, But as we are loged with the same LOG/PWD, firefox try to launch the same user hence we have to "execute" the cmd "firefox -p" and choose a different user profile. Is there a option or tips to "change automatically " the user profile if someone is already using the default profile? Thanks

Each Firefox process that is started by another user needs its own profile folder.

If Firefox runs entirely on a remote server, including the profile, then it won't work unless Firefox is started by specifying a separate profile folder for each user.
