Firefox running on plasma-mobile

Firefox 52

Install firefox-esr package from alpine. It is currently firefox 52.9.0-r1

Specific firefox config

Go in your profile directory (.mozilla/firefox/xxxxxxxx.default/) then exec:

echo 'user_pref("dom.w3c.touch_events.enabled", true);' >> prefs.js
echo 'user_pref("browser.gesture.pinch.in", "cmd_fullZoomReduce");' >> prefs.js
echo 'user_pref("browser.gesture.pinch.out", "cmd_fullZoomEnlarge");' >> prefs.js
echo 'user_pref("general.useragent.site_specific_overrides", false );' >> prefs.js
echo 'user_pref("general.useragent.override", "Mozilla/5.0 (Linux; Android 5.1.1; Nexus 5 Build/LMY48B; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/43.0.2357.65 Safari/537.361");' >> prefs.js

And restart the browser.

Configuration on gtk

Edit ~/.config/gtk-3.0/settings.ini with:

gtk-icon-theme-name = Paper
gtk-cursor-theme-name = Paper
gtk-fallback-icon-theme = Gnome
gtk-font-name = Sans 10
gtk-cursor-theme-size = 0
gtk-toolbar-style = GTK_TOOLBAR_BOTH
gtk-toolbar-icon-size = GTK_ICON_SIZE_LARGE_TOOLBAR
gtk-button-images = 0
gtk-menu-images = 1
gtk-enable-event-sounds = 1
gtk-enable-input-feedback-sounds = 1
gtk-xft-antialias = 1
gtk-xft-hinting = 0
gtk-xft-hintstyle = hintfull
gtk-xft-rgba = rgb

Make sure to install gnome-icon-theme and paper-icon-theme packages

You may ajust Font size for your screen.

Environment variables for starting Firefox

You can start firefox with:

MOZ_USE_XINPUT2=1 GDK_SCALE=3  firefox %u

You may ajust scale to your device screen size, but it may only be integers.

You can edit your desktop shortcut /usr/share/applications/firefox.desktop :

[Desktop Entry]
Exec=MOZ_USE_XINPUT2=1 GDK_SCALE=3  firefox %u

User agent

If you would like to switch between mobile and desktop page editions easily, the User Agent switcher extension will allow for easy switching between different user agents.

Upcoming versions

With upcoming versions (> 55) we will be able to use the multi-touch zoom extension to get fluid zooming. https://github.com/haxiomic/firefox-multi-touch-zoom
