Sorry for the poorly-worded summary. This only appears when running plasma-wayland. If a keyboard press causes a previously-focused window to become unfocused, and makes Firefox the newly-focused window, the key-press is passed to Firefox as a duplicate. To reproduce: Example 1 1. Make Firefox the selected window. Focus a textarea HTML widget. 2. Open plasma's default Application Launcher. 3. Hit "Enter" to open any selected item. Expected behaviour: No key press is passed to Firefox and the selected item is opened. Actual behaviour: The "Enter" keypress is passed to Firefox, creating a newline in the text area. If Firefox has a HTML anchor element selected, it is activated, potentially switching pages. Forms can be unintentionally submitted, etc. Example 2 1. Make Firefox the focused window. 2. Open a new application window, e.g. Kwrite or Konsole. 3. Use Alt+F4 to close the new window and make Firefox the focused window again. Expected behaviour: No key press is passed to Firefox and the previously-opened window is closed. Actual behaviour: The window is closed and the Firefox application menu (file, edit etc.) is focused.
Which XWayland version are you using?
Sorry, how would I go about finding the version number? Thanks.

Hmm I thought that XWayland version has this bug fixed...
Ok, I just compared. I'm already on XWayland 1.19 on Neon. Please update XWayland, it will fix this issue.
