Hello,
while dist-upgraders get Firefox-esr, siduction will switch from Iceweasel to Firefox with the next release.
Firefox will bring new features every six weeks and we embrace the change.
This only applies to four flavours as listed below.
Desktop Browser
Cinnamon Firefox
GNOME Firefox
Mate Firefox
KDE Firefox (Konqueror for internals)
LXDE Midori
LXQT Qupzilla
XFCE Chromium
Xorg ?
We are aware that webkit-based browsers are a security concern.
GNOME already dropped its epiphany browser for this reason, but yelp has similar issues.
KDE's Konqueror merely is meant to be used as a filemanager or for reading internal docs with its kio-integration.
Other lightweigth browsers like Midori, Qupzilla or even Xombrero ("Built with security in mind") share the same security concerns.
The rendering engine of Chromium, Blink, has been forked from webkit to speed up the development.
greetings
