#: Use the '''-no-remote''' and '''-profile''' command line switches. The '''-no-remote''' switch will allow multiple versions of the browser to run at the same time (i.e., otherwise it will open another window for your currently running instance). The '''-profile''' switch allows you to specify a path to a profile (e.g., a directory). This profile directory doesn't need to exist--it will create it if it is not there:<br/><br/><code>$ mozilla/''objdir''/dist/bin/firefox.exe -no-remote -profile some/path/testing</code>
