¶ Firefox
Firefox Developer Edition is pretty nice for getting features early
jc's Nightly install script includes The Ultimate .desktop application files.
¶ Estonian ID-Card and CORS Preflight
Firefox does not do TLS Mutual auth for CORS Preflight requests as mandated by Fetch standard.
Chrome ignores that and some websites rely on this behavior (https://api.lhv.eu/psd2/ui/auth/login).
https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS#preflight_requests_and_credentials
You can turn on Chrome like behavior in about:config
network.cors_preflight.allow_client_cert=true

¶ Wayland and smooth scroll and zoom
- Create few environment variables to enable Wayland and new input handler
# ~/.config/environment.d/99-firefox.conf
MOZ_USE_XINPUT2=1
MOZ_ENABLE_WAYLAND=1
GTK_USE_PORTAL=1
NB you need to restart your computer for systemd to register those environment variables
- In
about:configenable
layers.acceleration.force-enabled
apz.overscroll.enabled
apz.gtk.touchpad_pinch.enabled
To prevent touchscreen zooming gesture triggering the 100%, 125% keyboard-like zoom, set browser.gesture.pinch.threshold to 99999.
