I use FirefoxPortable on my pc (other than my usb drive)
On the PC Firefox is set as the default browser but nonetheless whenever I click on a file or call an URL in any other external way (another program) I get the "Firefox already running" message.
To be precise I get this message: "Firefox is already running, but not responding. To open a new window, you must first close the existing Firefox process, or restart your system"
Now, this message is given when 1) firefox isn't running at all (verified to the processes), or 2) it is running and also responding very well!!
now, 1) I haven't renamed FirefoxPortable,
2) I have set to allow multiple instances in the ini.file
3) the ini file is in the same directory as FirefoxPortable and works (as correctly doesn't display the splash screen, for example)
4) Firefox is correctly set as default browser in the registry
I haven't found any other suggestion in the forum as a workaround to this problem, so here I am.
Please help! Thanks!
