Profile copied to different computer not recognised
I'm running Firefox 122.0.1 on a Windows 10 desktop PC, with a profile which includes a userChrome.css file which makes several layout and cosmetic changes.
I also have a laptop (also Windows 10) which has an old Firefox 97.0.1 installation, and I'd like to make the same changes on this machine which I'm used to on the main computer. I copied my desktop profile to the laptop, to the same directory as its present profile, but when I rebooted Firefox the transferred profile wasn't recognised.
While doing the transfer I received error messages about some of the folders: Destination path too long. This despite the fact that the registry flag to accept extended paths is set to 1. I had to skip several folders in order to complete the transfer.
Could this be the reason why the new profile isn't being picked up? Or is it because the two Firefoxes are of different versions?
I'd be grateful for any thoughts. Many thanks.

My guess here is the newer version profile has information that the older version can't read so it can transfer those information and data to a older version as that can not read the newer data. It has to be 1:1 matching Firefox version for the data to transfer over if your doing just "copy". So you need to do the proper Firefox FAQ data transfer methods just copying will not work.
A simple method is to start Firefox with the ProfileManager and create a new Profile with the name you want. Shut down Firefox then find the new Profile you created and delete everything inside the newly created Profile. Then copy and paste over the contents from the old Profile into the new Profile. Then start Firefox with the ProfileManager and it should be there as a Profile to use.

Thanks for the speedy replies. I'll try both approaches tomorrow and see what happens.
