Same here for a couple months now. Firefox is my default browser if that has anything to do with it.

Same issue. KDE Plasma. Tumbleweed. I do not remember, when it stopped working, but I think few months ago.

Some logs:

Running on wayland. Qt WebEngine will disable usage of the GPU.
Note: you can set the QT_WEBENGINE_DISABLE_WAYLAND_WORKAROUND
environment variable before running this application, but this is 
not recommended since this usually causes applications to crash.

I think it is related to QtWebEngine. URI target to article displayed on OpenSUSE Tumbleweed on my VM.

I can confirm. My system info:

Last time I saw this it was this WebKit bug:

https://bugs.webkit.org/show_bug.cgi?id=230797

If you allowed Firefox to create default mime types for *.html and so on, this broke WebKit. Perhaps the bug exists in WebEngine as well and the fix needs to be ported.

Easy check is if you remove the Firefox files from ~/.local/share/mime/application/ (and recreate db with update-mime-database), does it work?

This workaround from Michael Catanzaro did fix the problem:
> > rm ~/.local/share/mime/packages/user-extension-html.xml
> > update-mime-database ~/.local/share/mime
Source: https://gitlab.gnome.org/GNOME/devhelp/-/issues/56

I found that it was already filed as a Qt bug, but they haven't made the connection or agreed it needs to be fixed:

https://bugreports.qt.io/browse/QTBUG-97392

Is this bug fixed? 
on TW and Leap I haven't had this issues anymore.

Just tested on current TW with KDE - still an issue

Have tested it again - well strange I got the same issue.
The DE doesn't matter in this case. It's on GNOME as well.

Further suggestions?

I don't know QtWebEngine well enough to understand if the WebKitGTK workaround applies directly. To recap there is a badly designed function in glib which causes Firefox to write malformed xdg-mime database files which then confuses WebEngine into not loading html files from disk. This is independent of desktop environment (see bug links in my previous comment).

This issue will appear on any system which has run Firefox at least once and allowed it to become "default browser".

Unfortunately as solving this properly appears to require cooperation across projects it is not receiving much attention ...

It is not repaired for me.

Well, indeed it's needs more attention. I don't know who's maintaining the welcome screen. Maybe it would make sense to chat with him and assign this bug.

This is an autogenerated message for OBS integration:

I updated Welcome Screen App from Plasma-Discover today. It seems to work, but no news bar is displayed. Maybe there is no news currently (server problems?) or somebody remove this functionality.

Sorry for previous post. It now working for me. Reason was I am use WiFI with password manager and I do not provide password before this screen appear. Previously I right-clicked and select refresh once connect via WiFI, but it do not work. Currently, I close app, connect to WiFI and launch it. News bar appear as expected.

Maybe submit bug refresh button not working properly or to add new update button to content of this window?
