New dual boot Linux configuration and all new install. Ubuntu 22.04 (all updates). Firefox 105.0.1. I am trying to create a new profile on a shared (ext4) partition that can be accessed from either boot side. I have tried over a dozen different configurations. I can create profiles anywhere on my local disk (also ext4). I cannot create a profile on the shared partition. Error msg: "Profile couldn’t be created. Probably the chosen folder isn’t writable." I have checked/verified permissions/directories/access/etc, checked for typos, tried using links or direct access. I tried copying a profile I created on the local disk onto the shared partition and just point to that. Notably when I choose the directory from the partition in the FF profile tool, FF switches the path to the /run/user/(...) tmpfs instead of using the actual directory as chosen. I verified access via this path as well. I even tried modifying the profiles.ini file to the "normal" location. Sorry for the long explanation. I have been configuring new Linux installs since the 90's. I'm stuck. Help??

Why not keep it simple and use sync to have your Firefox profile on both distros. I have 3 laptops that dual boot XP, 7, and 11 with openSUSE and use sync. see screenshot

Thank you for the option. I will certainly consider it. To be honest a profile on a shared filesystem seems even simpler though. I was a corporate sysadmin on complex Unix/Linux systems for almost 25 years. I certainly do not know everything, but this "should" work easily and I hate not knowing. I do appreciate the response. It is a viable approach.
