The original
Angelfish
A lightweight KDE web browser designed for mobile Linux devices that also runs on the desktop.
Replacements
Listings that take over the same core job as Angelfish.
Firefox
The main browser not built on Chromium, with tracking protection turned on by default.
Firefox runs on Linux desktops, Android and iOS with strong extension support and containers, but it is not designed around Plasma Mobile's touch interface the way Angelfish is.
GNOME Web
GNOME's browser, built on WebKitGTK, formerly known as Epiphany.
GNOME Web is another Linux-only open-source browser, using WebKitGTK instead of Qt and integrating with the GNOME desktop rather than KDE, with extension support that lags.
Falkon
Lightweight KDE browser built on QtWebEngine.
Falkon is a KDE browser on QtWebEngine with an ad blocker and password manager enabled out of the box, aimed at desktops and also available on Windows.
Konqueror
KDE's combined web browser and file manager, using Qt WebEngine for pages.
Konqueror stays within KDE and Qt WebEngine but combines browsing with file management and FTP/SFTP, fitting a Plasma desktop better than a touch-first phone.
Chromium
The open-source browser project that Chrome, Edge, Brave, Opera and Vivaldi are all built from.
Chromium gives you the upstream open-source engine packaged by most Linux distributions, with no Google sign-in, but it lacks Widevine DRM in most builds and any KDE integration.
Midori
Lightweight browser with an ad blocker and privacy-focused defaults.
Midori is a lightweight open-source browser with ad blocking and tracking protection enabled by default, available for Linux, Windows and Android, though maintained by a small team.
