How to clean cookies from a second/portable (!) Firefox?

On my Win7 system I have two independent Firefox installations:

- The first "normal" installation of v58.0.2

- The second, portable Firefox v52.60 Firefox ESR version

In CCleaner I defined a couple of Cookies which should be kept.

When I run now CCleaner it detects and cleans successfully the cookies of the first Firefox installation since it knows the profile path from registry.

Unfortunately CCleaner does NOT recognize and clean the second Firefox installation.

Is there a way to let CCleaner clean the second Firefox installation (especially the cookies which are not in the "keep"list) as well?
