Hello Paul!
Not a KDE user on my Arch Box, but I was able to achieve somewhat what
you want on my Ubuntu 21.04 tablet with Plasma 5.21.4 under X11. It's
a way to basically trigger certain actions (or not) through keystrokes,
depending on the active window (among other things). This feature is
hidden in the Settings under Shortcuts > Custom Shortcuts.
There you can define a group that matches certain windows, like Firefox,
and remap Ctrl+W via a so-called global shortcut (which is misleading,
since the group defines that only Firefox windows should be
matched). Some documentation I found online is this PDF from KDE [1].

Has anyone been able to figure out how to disable the Ctrl-W shortcut in Firefox? As a Vim user I'm constantly accidentally closing tabs when I want to delete the last word in a text field.
It seems to be _very_ difficult to find a reliable method to do this short of recompiling Firefox. I use Plasma Desktop. If there's some way to filter events going to the browser window, that's a viable solution too, but I haven't found any way so far.
Many thanks, Paul
