As with others I can't find my old profile. I renamed it long ago as my primary profile and have updated firefox many times since. On Sat 8/14 I updated Sahara and my profile won't reload, instead I'm getting a window claiming the profile is too old. I've been through and through the FAQs and am not enough of a successful user to get to the right folder to find a usable profile with my data still in tact. about:profiles, where I usually go now had 43 profiles in it including my previously renamed profile but that doesn't help. I refreshed ff without success. I tried to find help in the many profiles help pages that said click on this, copy this, click on the profile tab, go up one level and turn left and you lost me. Can anybody help me find my usable profile and simply explain how do I re-initiate it? Thanks.

The System Details list shows you are currently using a very outdated Firefox 68 version.

  • User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:69.0) Gecko/20100101 Firefox/69.0

Any specific reason for using this unsupported old version and not the current release ?

Firefox 67 and newer use a dedicated profile for each Firefox installation and lock this profile to prevent other Firefox installations from using this profile. Firefox also prevents downgrading a profile and warn you if you run a Firefox version that is older than the version that last used this profile.
