I installed two versions of Firefox on my PC. (I did this because an update caused me to lose my data!) Now, I would like to uninstall one of the 2 versions! The situation, however, is this: Mozilla Firefox (x64 it) - 91.0.2 : acttual version: 115.6.0 (7/1/2024) installation of 28/8/2021 (\exe91)


Mozilla Firefox 85.0 (x64 it) - 85.0 .  : acttual version: 115.20.0 (5/2/2025) installation of 3/3/2024 (\exe85)


Mozilla Firefox ESR (x64 it) - 115.9.1 : installation of 29/3/2024 (\exe91)


Mozilla Firefox ESR (x64 it) - 115.20.0 : installation of 5/2/2025 (\exe85)


Each installation was done in different directories. I hope this trick will allow me to uninstall a version without causing any problems... Can anyone confirm this? Thanks for the reply! Regards.
