Plasma Wayland session with git master everything. STEPS TO REPRODUCE 1. Open Firefox 2. Click and drag a link on a page (any link, any page) 3. Drop it a few mm away anywhere OBSERVED RESULT The cursor gets stuck as a grabbing hand while it's within the Firefox window
I can reproduce on Plasma 5.20 beta with Firefox running natively on Wayland. bug 400014 is a similar issue.
> while it's within the Firefox window This sounds like a ff bug. Can you reproduce this bug with other wayland compositors?
No, I cannot reproduce the issue with Weston. In fact, dragging a link in Firefox under Weston shows no grabby hand at all.
and I can't reproduce on Wayland session of Gnome 3.38.1.
Yep, can confirm.

Git commit aa42b54004d07f58253f7bd4f0e5d69b2466cd33 by Vlad Zahorodnii. Committed on 28/10/2020 at 17:42. Pushed by vladz into branch 'master'. Send a cancelled() event if the dnd data source is not accepted Currently, Firefox will stuck in "dnd" mode if you try to drag any of its tabs. The main reason for that is that kwin doesn't send the wl_data_source.cancelled event if the pointer button has been released and there is no target surface or if the data source hasn't been accepted by anyone.

So, the problem was that kwin didn't send an event to indicate that a drag has been cancelled. With aa42b54004d07f58253f7bd4f0e5d69b2466cd33, the cursor should be normal after a drop. However, I've noticed that dnd and copy pasting stop working in firefox after you use it for a while. What's more interesting is that I can reproduce the same issue with weston...
For the most part, dragging-and-dropping works fine with Firefox now, so I'm closing this bug report.

For the record: this is tracked in https://bugzilla.mozilla.org/show_bug.cgi?id=1622107 and a known issue, on all compositors.
@Robert Aha, that's good to know. Thank you! :-)
Verified fixed, but while testing, I found a similar issue for the desktop: Bug 428747
This is still happening for me (Arch Linux, KWin Wayland version 2.25.5, Firefox version 105.0.2, entire system up to date as of 2022-10-06). Dragging anything on the page (link, selected text) will cause the cursor to get stuck as a grabbing hand.
Can confirm. I assume this is a recent regression because it worked fine in the past.
I am affected by the issue too. I can temporarily resolve the issue by dragging a tab outside of Firefox (creating a new window)
Possibly fixed by this patch merged recently https://invent.kde.org/plasma/kwin/-/merge_requests/3110
