Task manager - Firefox - only one icon shown in task manager

[John Horne]

Hello,

Using plasma/wayland on Fedora 34, I have noticed recently that if I invoke
Firefox, then an icon (with text) appears in the task manager. However, any
subsequent invocations of Firefox, via the system tray, do not appear - no
icon, no text.

For my set up, I have configured the task manager such that applications should
show an icon with text, no grouping and no sorting, and using 2 rows maximum.
(I rarely have many applications open at once.) I have added the Firefox
application icon to the panel.

This used to work fine, but some recent change must have occurred. The problem
does not occur, for example, with konsole or chrome, they show multiple
icons/text if invoked multiple times - it just seems to be Firefox that only
appears once. I can, of course, get around the problem by using Alt-Tab to show
open windows.

Has anyone else noticed this? Or anyone any ideas of how to get the former
behaviour - multiple icons/text? I wouldn't have thought that Firefox itself
has an option to deal with the KDE panel/task manager. I have tried looking
(googling) for something specific to Firefox and the task manager, but can't
really find anything relevant.

O/S: Fedora 34
Kwin-wayland: 5.22.4
Kf5-plasma: 5.83.0
Firefox: 90.0.2



Thanks,

John.

I just recently noticed this as well.  There appears to be a new(?)
Task Manager Behavior setting in the "Clicking grouped task" drop-down.

I changed it (or changed it back) to "Shows textual list" to restore the
old behavior.

Thanks for that, but sorry, no, that made no difference.

I ran up a KDE Fedora 34 spin under kvm. No patches applied, I configured the
task manager how I like it and it worked fine. Firefox showed multiple times if
I clicked on it multiple times.
I then applied the F34 patches (via dnf) and rebooted. Again, the task manager
and Firefox worked as expected.
I have also checked this list archives as I feel that the problem was reported
before. Couldn't find anything relevant though. I also checked the current KDE
bugs, but couldn't find anything, although my searching may not have been good.
I'll have another look later on.

Hello,

For Fedora it seems that there is a 'firefox-wayland' package available. What
this does is provide a small shell wrapper which sets an environment variable
- MOZ_ENABLE_WAYLAND=1 - and then invokes the main firefox program.

I have replaced the standard firefox panel shortcut with the one from the
firefox-wayland package (it looks exactly the same).

This works fine. If I click on the icon 3 or 4 times, then I get 3 or 4 items
appearing in the task manager. If I click on the standard firefox package
shortcut 3 or 4 times then I get 1, maybe 2, items appearing in the task
manager. I then have to use alt-tab to switch between the different browser
windows.
