Announcement

**Schwarzer Kater** · Mar 30, 2023, 12:28 PM

Changelog

Version 1.2.1, released 2023-06-21
- improved code
Version 1.2.0, released 2023-04-25
- ADDED FEATURE to offer removing the Firefox Snap and strongly recommend to do
so, if Firefox from the Mozilla Team PPA is to be installed
- cleaned up code
- improved summary
- improved language
- renamed the project
Version 1.1.2, released 2023-04-07
- CORRECTED BUG IN CODE (now the "invisible" placeholder files for a former
installation from the Mozilla Team PPA are removed, if the user installs Firefox
from Mozilla.org instead after running the "reinstall_Snap_for_release-upgrade"
script)
- improved code
- improved output
Version 1.1.1, released 2023-04-06
- CORRECTED BUG IN CODE (now the firefox.desktop file for Firefox from
Mozilla.org is created in /usr/local/share/applications instead of
/usr/share/applications - otherwise in some situations the .desktop file could
be removed when (re)installing the Firefox Snap or release-upgrading)
- improved summary
- improved comments
Version 1.1.0, released 2023-04-03
- ADDED FEATURE to save summary as a text file for future reference, if the
script had changed anything
- changed version number to semantic versioning
Version 290323, released 2023-03-29
- initial public release

Something like a temporary FAQ can be found here: https://www.kubuntuforums.net/forum/...600#post669600

The script has been tested extensively, but I appreciate it if you report any errors you come across (concerning the coding or the English language).

Thank you very much!

# This is a little helper script for Kubuntu™ users who want to install the    #
# traditional Firefox from Mozilla.org like Debian suggests and use it         #
# complementary to / instead of the Firefox Snap OR for users who want to      #
# install the traditional Firefox from the Mozilla Team PPA like KDE neon does #
# and use it INSTEAD of the Firefox Snap.                                      #
# It has been tested many times with Kubuntu™ 22.04, 22.10 and 23.04.          #
#                                                                              #
# -> IMPORTANT:                                                                #
#    It is advised to run this script after a full upgrade of the system       #
#    (either with Discover or in Konsole with "sudo apt update && sudo apt     #
#    full-upgrade") AND a reboot.                                              #
#                                                                              #
# -> Firefox from Mozilla.org can simply be used alternatively with or without #
#    the Firefox Snap and no further actions are to be taken.                  #
#    If you choose Firefox from Mozilla.org you are asked to select your       #
#    preferred language first.                                                 #
#    This version of Firefox behaves roughly like the ones for macOS™ or       #
#    Windows™ do and updates itself independently from Discover or APT package #
#    management (and can ask you before updating - if you would prefer being   #
#    asked see the Firefox settings).                                          #
#                                                                              #
# -> Firefox from the Mozilla Team PPA should be used INSTEAD of the Firefox   #
#    Snap. This script will offer you to remove the Firefox Snap if it is      #
#    installed. Alternatively you could also use the "get_rid_of_Snap" script  #
#    to disable and block Snaps completely including the Firefox Snap.         #
#    If you choose to use the Mozilla Team PPA additionally APT pinning is     #
#    applied to prefer this Firefox to the Snap version e.g. during updates.   #
#    Updates are handled by Discover or APT package management like for the    #
#    rest of your system and you could ALSO get Thunderbird from this PPA.     #
#    Sometimes the Firefox and Thunderbird versions from the Mozilla Team PPA  #
#    are not yet officially released (kind of "release candidate" versions),   #
#    but so far nobody has reported any problems with them AFAIK. Mostly these #
#    versions are officially released only a few hours or days later.          #
#    The Mozilla Team PPA and appropriate APT pinning are both respected by    #
#    the "reinstall_Snap_for_release-upgrade" and "get_rid_of_Snap" scripts.   #
#                                                                              #
# You will be asked to choose between Firefox from either [1] Mozilla.org or   #
# [2] the Mozilla Team PPA before the download and installation is started,    #
# but if you choose [3] to cancel the installation no changes at all are made  #
# to your system. Personally I prefer Firefox from Mozilla.org due to its      #
# versatility regarding Snap and release-upgrades.                             #
#                                                                              #

I recommend De-Snapping your install prior to running this: https://www.kubuntuforums.net/forum/...et-rid-of-snap

**Schwarzer Kater** · Mar 30, 2023, 01:40 PM

-> Firefox from Mozilla.org can be used with or without Snap easily, regardless the Kubuntu version or if you want to release-upgrade or not.

-> For Firefox from the Mozilla Team PPA I indeed strongly recommend to remove Snap - either do it by the given option in this script or use the "get_rid_of_Snap" and "reinstall_Snap_for_release-upgrade" scripts (they will automatically take care of everything "Firefox from the Mozilla Team PPA"-related for you).

But one could also use Firefox from the Mozilla Team PPA additionally to the Firefox Snap version or Snap in general.
One of the problems then are the conflicting entries/.desktop files for the (KDE) application menu…
Also it gets a bit more complicated when you do a release-upgrade (due to the necessary manual removal of APT pinning for Firefox before and re-enabling of the Mozilla Team PPA and reapplying of the Firefox APT pinning and reinstallation after the release-upgrade).

If one wants to keep using Snap and manually removes the APT pinning for Firefox from the Mozilla Team PPA and deinstalls Firefox from the Mozilla Team PPA before the release-upgrade, the three necessary steps after the release-upgrade can be done with this "install_traditional_Firefox" script again.
