You can use pretty much any browser that supports wayland. The default is chromium.

▲ sign> echo "#!/bin/sh
URL=http://example.com/
--enable-features=UseOzonePlatform --ozone-platform=wayland \
--start-fullscreen --noerrdialogs --disable-infobars --disk-cache-dir=/dev/null \
--disk-cache-size=1 '\$URL' &
while true; do
# after a while all browsers begin to stutter. Here is a crude fix
sleep 600
WAYLAND_DISPLAY=wayland-1 wtype -P F5
done" >
=== setup browser (falkon) ===
In case you don't want to use chromium you can also use another browser. For instance falkon.
* install and autostart falkon
sign> apk add falkon font-noto
▲ sign> echo "#!/bin/sh
URL=http://example.com/
sleep 600
WAYLAND_DISPLAY=wayland-1 wtype -P F5
