There is a new appliacation available for Sparkers: the first release of Falkon web browser 3.0.0.

From Wikipedia:

Falkon (formerly QupZilla) is a free and open-source web browser, intended for general users. Falkon is licensed under GPLv3.
Falkon makes use of Qt WebEngine to support modern web standards. It provides several icon sets and other elements to match the native look and feel of users’ desktop operating systems.

David Rosca said:

Falkon is a new KDE web browser, previously known as QupZilla. Following this release, there will only be one last final QupZilla release.

If you were previously using QupZilla, you can manually migrate your profiles to Falkon by moving the config directory (usually in ~/.config/qupzilla/).
There is no automatic migration.

sudo apt update
sudo apt install falkon

or via Sparky Web Browser Installer >= 20180307.

Then run the application from menu-> Internet

Due it needs Qt 5.9, the app is available to Debian testing/Sid and Sparky 5 only, but not older.
