I'm trying to get my wife's firefox browsers synced - mainly her laptop and phone. I've got the phone signed in and working fine, but on her laptop there's no option to sign in and the sync option is missing from the settings menu? It seems to be profile related as if I create a new blank profile the option is there - but if I copy all the data from her original profile the option goes missing again. Short of manually copying all her data over, I'm a bit stuck for what to do next - any ideas? I've tried disabling any addons, restarting in troubleshooting mode etc. I've also looked at all the other solutions I can find from here (mostly related to group policies, there's nothing enabled on this) and everything seems as it should be. I haven't tried reinstalling, but it seems like this is a profile issue rather than an installation issue? It's a Win 11 laptop (upgraded from W10 if that makes a difference), FF version is 135.0 64 bit. Thanks!
