Testing out LW now as well. Utilizing the keepassxc extension to switch over from protonpass, too.
Just in case you have any issues w/KeepassXC and LW (as I did, briefly): https://github.com/keepassxreboot/keepassxc-browser/wiki/Troubleshooting-guide
LibreWolf relies on Mozilla’s Gecko engine, so LibreWolf mostly doesn’t exist without Firefox/Mozilla. I wish there was a way to just donate to the Gecko engine maintenance to keep a Chrome alternative running without supporting all the other Firefox/Mozilla stuff.
I started using it as well last week, and so far it just feels like a drop in replacement. If you were using Firefox Sync, you can just enable it and your whole profile will get transferred over.
