Updating FirefoxIf you would like to update to a new version, simply download the new Firefox AppImage.The Firefox AppImage also can be updated using AppImageUpdate. Using this tool, Firefox can be updated by downloading only the portions of the AppImage that have actually changed since the last version.
From FlathubMozilla provides an official FlatPak at FlatHub.If you haven't already set up flatpak, runsudo apt install flatpakflatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepoInstall it:flatpak install flathub org.mozilla.firefoxRun it:flatpak run org.mozilla.firefoxIf you have added /var/lib/flatpak/exports/bin to your PATH, you can also run it with the commandorg.mozilla.firefox If you want to use your Firefox flatpak as the default DebianAlternatives browser (x-www-browser), run sudo update-alternatives --install /usr/bin/x-www-browser x-www-browser /var/lib/flatpak/exports/bin/org.mozilla.firefox 200 && sudo update-alternatives --set x-www-browser /var/lib/flatpak/exports/bin/org.mozilla.firefoxFlatpaks don't support native messaging. Therefore, add-ons which rely on it such as KeePassXC Browser don't work. A workaround for KeePassXC is described in the Flathub forum. Since the KeePassXC's socket has been renamed in KeePassXC 2.6, for this version you need to tweak the solution as described in comment #3
h2o bedankt voor je advies, zo heeft elk voordeel ook weer zijn nadeel.Maar nou weet ik nog niet waarom ik die melding krijg wanneer ik "AppImageupdate" uitvoer.
