Firefox★★★★☆I still have a soft spot for Firefox. At times it’s been the best web browser on Windows and Linux. It’s still good, has a solid extension ecosystem, and serves as an important bulwark against one company dominating browser tech.
Firefox Sync★★★★☆Works on nearly every Firefox-based browser and can mix and match. Even IronFox and LibreWolf recommend using it, as it’s encrypted end-to-end.
GNU IceCat★★★☆☆Firefox minus all branding and connections to Mozilla services, plus add-ons to block non-FSF-approved JavaScript.
IronFox★★★★☆A privacy-hardened Firefox variation for Android, comparable to LibreWolf on desktops. Removes Mozilla tracking and services like Pocket. Locks down features that can leak data, but those changes can break some sites.
LibreWolf★★★★☆Customized Firefox, with an eye toward security and privacy. Follows the stable release channel. Works well most of the time, but privacy features can break some sites.
Regarding Mozilla and BraveOn Brendan Eich’s brief promotion to CEO at Mozilla, the fallout for Mozilla and the creation of Brave.
SeaMonkey (Internet Suite)★★★☆☆The old Mozilla Suite lives on! Featuring web, email, news, an HTML editor, IRC client and more. Recent work has mostly been to keep it working and backport security fixes, so web app compatibility lags way behind even the ESR Firefox.
Thunderbird (Email and Calendar)★★★★★Stable, capable desktop email application, works well with multiple accounts including Gmail, Nextcloud, easy to set up and use but with advanced settings when you need them. FLOSS.
Tor Browser★★★★☆When you really want (or need) to stay private while using the web, Tor is the way to go. Just keep the drawbacks in mind when you do.
Waterfox★★★★☆A Firefox fork aimed at improved performance and privacy, without sacrificing usability. Also available on Android.
Zen Browser★★★★☆Similar to Arc, Zen has a non-cluttered design that stays out of your way. Unlike Arc, it’s built on Firefox, runs on more platforms, and doesn’t require you to log in just to use it!
