    Cons:

    • as base is used a very old version of Firefox
    • bad user experience (interface)
    • an very old (and probably already unsupported) version of Sync
    • no support for modern plugins, extensions and themes

    Good for working with dated web technologies or operating systems. Extensions are much easier to find, as they're based on old Firefox APIs.

    It's a relatively new fork worth trying. It already has a sizeable community.

    Not as overkill as Tor Browser, but still a bit hostile for everyday use.

    Falkon's really fast even on low-end hardware. Add-ons are still really sparse though, and I haven't found a good way to sync bookmarks or connect it to KeePassXC yet.

    It isn't really bad, but not a lot of add-ons and based con Qtweb (chromium). Not fingerprinting protection like Firefox but also no telemetry by default. It is ok, but it could be better.
