LibreWolf is one of the better Firefox forks but it doesn't have automatic updates and you're relying on a relatively small team to keep it up-to-date.
At that point, Mullvad Browser would be a better choice.
That's not accurate. LibreWolf has an automatic updater for Windows.[1] On Linux, updates for most applications are handled by the operating system's package manager, and LibreWolf also maintains a Flatpak.[2] On macOS, LibreWolf has a Homebrew cask.[3] Flatpak and Homebrew can be configured for automatic updates.
I've been very satisifed with LibreWolf and haven't experienced any significant issues.
> Mullvad Browser would be a better choice
Mullvad Browser is a nice fork, but it doesn't include any syncing (like Firefox Sync), which makes it a non-starter as a primary browser for anyone who uses that feature.
