firefox not responsive when typing in address bar or web based search box

[Bevan]

Firefox 87 by Ubuntu in plasma Wayland 21.04 is not responsive when typing in the address bar or text boxes.

I am trying to type a URL in the address bar or text for searching. I will only let me type 2 or 3 characters of text then it seems to lock up. Can't even select text with a mouse.

I think it is doing this in the background but doesn't display on screen as me doing anything.

I don't have this issue with the Firefox which I downloaded directly from Mozilla. Furthermore, I just unzip the file and run the Firefox bin file.

If I run Ubuntu Firefox in x11 I don't have these issues.

Running firefox from terminal gives them message
(firefox:74754): Gdk-CRITICAL **: 21:15:01.027: gdk_wayland_window_set_dbus_properties_libgtk_only: assertion 'GDK_IS_WAYLAND_WINDOW (window)' failed

I get the same message even in safemode and the same issues.

cpu is between 5% and 30% with firefox
