All FF-Portables are crammed together suddenly instead of several instances

Hi

For ages, I'm using Firefox_1.exe, Firefox_2.exe etc. having two separate instances of Firefox available.

But suddenly a few weeks ago, this wouldn't work anymore: Firefox instances are crammed in a single Firefox-Icon on the toolbar even though the exe-files have different names
Well, I had to add "-no-remote" in order to be able to start more than one of them...
Otherwise I haven't changed anything.

I tried to use Firefox-path instead of Firefox64-path but no difference as well as the ini-entry about always 32bit parameter.

I noticed that the profile path of the firefoxportable.ini doesn't seem to work anymore because the "about:profiles" shows the regular firefox profile path and not the "Data\profile" path.

Do you have any idea, how to fix this, so that there will be again several Firefox instances running and not everything crammed together?

Thanks for your help or suggestions
