running portable firefox
i've spent some time on making my own version of portable firefox (locales, plugins, additional search plugins etc.). After i had compiled launcher using NSIS 2.22, i spotted a problem: Portable Firefox opens another instance of already running regular firefox instead of showing a message, and closing. Everything seems to be OK, when regular firefox is turned of. I think, the solution is in the INI file(s), or in *nsi scripts, but i can't find it. Does anyone had same / similar problem, and solved it? Please help.
