I'm pretty sure it used to be possible to have two separate Firefox Portable instances (Different folders with different profiles in them) and use them simultaneously with AllowMultipleInstances=true in the settings file. This seems to not work any more. Is there another option to have two separate instances of FF portable and having them run simultaneously?
Thank you!

A few options here:
* If you want to run multiple profiles: https://portableapps.com/support/firefox_portable#second_profile
* I believe it's also possible just run Firefox and Firefox ESR together without additional configuration.
* You can also open the file FirefoxPortable\Other\Source\FirefoxPortable.ini in a text editor and change "AllowMultipleInstances" to "true" and then save changes.
