Firefox
Firefox is a popular, open-source web browser.
Installation
To install Firefox, firstly enable the Community repository, then type in the terminal:
For the Extended Support Release (ESR) (firefox-esr):
# apk add firefox-esr
For the current release (firefox):
# apk add firefox
Alternatives
The Alpine packages do not disable most telemetry and similar tracking shipped by upstream. Consider using librewolf, a privacy-centric fork which disables Mozilla's first-party spyware and analytics:
# apk add librewolf
Stability
If tabs crash, then try disabling hardware acceleration, in the Preferences - Performance menu.
Notifications
For Firefox to use native notifications (e.g.: via a notification daemon) the libnotify package is required.
DRM content using Widevine workaround
As per #16783, to play DRM content using Widevine(i.e Spotify and other streaming websites) you will have to manually configure it up. Install the necessary packages:
GMP sandbox needs to be disabled on launch:
$ MOZ_DISABLE_GMP_SANDBOX=1 firefox
Now open about:config and enable media.gmp-widevinecdm.enabled and media.gmp-widevinecdm.visible.
Open a DRM Stream test to load the plugin then patch the library:
$ patchelf --add-needed libgcompat.so.0 ~/.mozilla/firefox/*/gmp-widevinecdm/*/libwidevinecdm.so
Finally, reload the page and it should be working.
Once the above steps are carried out once, use the command $ MOZ_DISABLE_GMP_SANDBOX=1 firefox to launch Firefox whenever DRM content needs to played.
$ MOZ_DISABLE_GMP_SANDBOX=1 firefox only when playing content from trusted sites.
