User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; be-BY; rv:1.8.0.4) Gecko/20060508 Firefox/1.5.0.4 Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; be-BY; rv:1.8.0.4) Gecko/20060508 Firefox/1.5.0.4 I moved profile directory on the flash disk(for share firefox data between work and home computers). When I run firefox WITH flash disk, it works perfect. When I run firefox WITHOUT flash disk(i.e. profile directory can't be found), firefox reports : "Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system.". It happen in firefox 1.5.0.4 and Firefox 2 beta1 Reproducible: Always Steps to Reproduce: 1. Remove profile directory(but leave it in profile.ini), or change Path in the profile.ini into non-exists directory 2. Run firefox Expected Results: Seems to firefox should report other message.

This is a dup.
