How to run 2nd instance of firefox without any profile (or with some dummy profile that will be deleted on exit) ?

iexcept

I use FF as my primary browser and I want to run second fresh instance of it for some testing purposes.

I am aware about: firefox -no-remote -P "Another Profile" but this is not suitable for me as it requires me to create a new profile first.

Hi

You may wish to try installing Firefox Developer Edition, a pre-Release version of Firefox that uses a separate profile from other Firefox versions installed on your machine. This means you can easily run the Developer Edition alongside your release or Beta version of Firefox.

You can learn more about and download Firefox Developer Edition from here.

thank you so much!
