Falkon is a very fast web browser that uses QtWebEngine, and aims to be lightweight on all major platforms. It has all the standard functions that are expected from a web browser, including bookmarks, history, sidebar, and tabs. Plus: integral AdBlock, and editing of the local CA certificate database with an SSL manager. Falkon has a wide range of features that are supported by KDE Frameworks, and many integration points with KDE Plasma. The "qtonly" flavor omits these features: - spellchecking - word completion - crash reporting - progress notifications - KIO (virtual filesystem) support - wallet integration - content sharing.
