ADDITIONAL INFORMATION
Where clipboard works:

I believe this issue is NOT related to bugs:

I vaguely remember that the issue with wayland firefox clipboard in plasma wayland session was connected to (don't take my word for it) 'multiple presented clipboard interfaces' from firefox but I cannot find the related bug report. This was already fixed so maybe the one clipboard read but plasma is the wrong one now? I've no idea.

Or should I report this to mozzila since their update broke things? :)

After more testing I can see that this problem is only related to address bar in firefox. Copying from within browser viewport is fine. Even from native GTK widgets (such as textfields) rendered in page.

I will investigate further.

It's not just Firefox's address bar. The password vault also does not allow you to copy (in my case to XWayland applications). Copying from the main viewport works however.

I remember this issue. After updating to 84, it's gone.

Comment 4 Martin Kostolný 2021-01-26 23:33:01 UTC

I've now tried Firefox 85 on Arch Linux and cannot indeed reproduce this issue anymore.

However problem persists on Gentoo. I'll ask there.

Closing issue here, thanks for your input! :-)

For anybody who wander here seeking solution - updating gtk+ from 3.24.22 to 3.24.24 fixed the issue for me.
