  • Fedora’s Thunderbird Flatpak shows generic Wayland “W” icon in KDE Plasma

    Just a little annoying issue that has buggered me for many months without any solution in the updates.

    When launching the latest Fedora version of Thunderbird Flatpak (128.6.0esr), it does not display its usual stylised blue swallow icon, but instead the generic yellow “W” icon of Wayland.

    This system runs Fedora Kinoite so the bug probable does not affect a RPM installation of Thunderbird. Additionally, there is also a Flatpak version of Thunderbird in Flathub which I have not tested whether this bug is present or not.

    This issue appears to be due to how the Thunderbird Flatpak is packaged. Specifically, the Fedora provided Flatpak is not setting the expected desktop file metadata when it launches under Wayland. As a result, KDE Plasma falls back to the generic “W” icon for the running window, even though the menu and pinned icon are correct.

    There is a specific commit to the underlying Flatpak container.yaml which may be responsible for this bug. The changing of the name string from “org.mozilla.thunderbird” to “net.thunderbird.Thunderbird“. This hint is also what is used to work around the bug:

    1. Start by opening Thunderbird
    2. Press Alt+F3
    3. Select More Actions > Configure Special Application Settings
    4. Add a new property called Desktop file name
    5. Select “Force” in the property drop-down
    6. Change the property value to “org.mozilla.Thunderbird“
    7. Click “OK“

    Now the taskbar icon should be back to the same as the one in the menu, the correct Thunderbird blue swallow icon, with no sight of the wrong yellow Wayland “W” icon.

  • Running several Firefox versions simultaneously

    Ever been in the need of running more than one instance of Mozilla Firefox? Well, I have. Multiple times.

    I use Firefox for my browsing and development. Combining both in the same profile has been a pain many times especially when ones development is intensive leading to high memory and CPU consumption unfortunately ending with a browser crash.

    Some time ago I starting using Firefox Beta since it included the Sync feature built-in. At some point I wanted to revert back to the release version again as the add-ons needed to be ready for Beta as well and it could take the add-on authors some time to update leaving them disabled till then.

    The easiest thing is to run two or more versions simultaneously of Firefox which provides you with increased flexibility, especially if you do web development of any type.

    To proceed simply download another version of Firefox and install selecting the custom choice. Make sure you install it in a different path than your current Firefox installation.

    The key to get more than one instance of Firefox running is to use multiple profiles. To create an additional profile for your next version open the command prompt (if on Windows) and type the following:

    "C:\Program Files\Mozilla Firefox" -profilemanager -no-remote

    Obviously change the path to match your own system if needed.

     

     

    Now the profile manager should be open and you can simply create a new profile and call it something else like e.g. “BETA”. Then click “Exit” afterwards to quit the profile manager.

     

     

    Next you need to edit the launcher of your newest installation of Firefox, by right-clicking its icon in the Start menu and selecting Properties. At the first text box add the following to the path:

    -P yournewprofilename -no-remote

    So it looks something like this:

    "C:\Program Files\Mozilla Firefox Beta\firefox.exe" -P BETA -no-remote

     

    Save and launch your second instance of Firefox by clicking on the same icon. You should now see two different “Firefox.exe” processes in your task manager.

     

     

    In that same screen you were before you can also change the title and icon itself so that it is easier to distinguish which version is which.
