I honestly wonder if the OP in that thread is in good faith or has some other problem screwing up his config. No, neither FF nor LW randomly change settings on you; you have some process, somewhere, that is either corrupting the sqlite db or straight up changing the config.
Anyway, if you literally did a web search
how to enable mozilla sync in librewolf
you would get the correct answer, which works for 99.99% of people 99.99% of the time:
To enable Mozilla Sync in LibreWolf, go to the about:config page and set the option "identity.fxaccounts.enabled" to true. After that, you should be able to log in to your Firefox account and use the sync features.
What are you even talking about? I use LibreWolf with the Mozilla password manager. It’s a one click enable
LibreWolf is what FireFox was supposed to be: no VPN ads, no telemetry, no AI, uBlockOrigin built in. It’s literally the latest FF release, but with the crap ripped out and decent privacy installed.
