Android and reverting to older Firefox version

[RaceQ]

I have Android 5.0.1 and Firefox 56.0 installed if I uninstall Firefox 56 and reinstall Firefox 54.0.1 will what will happen to my profile data will it still be available after going down to version 54.0.1? And yes I know the security implications of doing that but I need to be able to move firefox to the external SD card. The Smart phone does not have root access.

Uninstalling Firefox on Android will remove your profile.
