Problem with running two profiles simultaneously and opening external links

I am trying to run two instances of Firefox simultaneously with two different profiles so i changed AllowMultipleInstances to True and it worked but now if i try to open a link from external program i receive "Firefox is already running but not responding"

What i have to do so i can open external links and run two Firefox profiles simultaneously?

You Can't

When 2 copies of Firefox are running, it doesn't know which one to pass it off to. Firefox's multiple instance support is not meant for production use, just testing.

Sometimes, the impossible can become possible, if you're awesome!

So, if i want to launch a second profile i have to close the first one. Damn, that's not convenient...

Isn't possible to use -no-remote parameter for the second profile as this can be done with installed version of Firefox?

No

You can use two profiles simultaneously without issue. While doing so, however, you can not click links from other apps and have them passed to either Firefox. Normally, the firefox.exe accepts the URL and passes it to the already running copy. In this case, it can't since it doesn't know what instance to pass it to.

AllowMultipleInstances uses -no-remote. This is its expected and documented behavior.

Drag and Drop

@Peter8087

It isn't quite as convenient, but you can often drag-and-drop links from one window to another.

Next time you have multiple profiles open and want to open a link in one of them try dragging the link to the desired browser window. If you want to open it in a new tab, drop it in the blank area in Firefox's tab bar (or on the tab bar's plus sign).
