I know there's been more than a few posts about multiple instances of FFP but I don't recall seeing one that was my specific question. Most involved different versions or an installed version and a portable version. I am wondering if it is possible to run multiple FFPs of the same version just from different folders. I have tried the AllowMultipleInstances=true parameter in the past but that just resulted in a link being clicked from outside FFP opening Firefox in a new window void of extensions and theme and all that. That isn't what I am after.
If I can illustrate below what I am after, I will label them FFP1 and FFP2 to discern them.
D:\FFP1\FirefoxPortable.exe is the main browser that's used and set as default for opening links from other apps and the like as well.
D:\FFP2\FirefoxPortable.exe is used for a different specific purpose that is separate from FFP1.
When I click links from other apps I want them to open only in FFP1 and not in FFP2.
The issue I have come across in the past using the AllowMultipleInstances=true parameter in the .ini file is that it would then open a new window instead of a new tab in FFP1. That new window would also not have any extensions and for all intents and purposes be like a fresh installed Firefox install.
The problem I run into with this scenario though is that trying to start FFP2 detects FFP1 running and says Firefox is already running and to please close the already running one to run that one.
The other issue I guess I have is that I know its possible to do this cause Waterfox Portable can already do this just fine without issues and doesn't detect the already running version as running and opens the second one anyway.
