This happens only when middle-clicking links, but not right-clicking and opening them in a new tab. It also doesn't happen when I middle-click a tab to close it.

I'm using Firefox 112 on a KDE plasma archlinux session using wayland, the system is all up to date.

I've recorded a profile of the ~10 seconds while the UI is frozen: https://share.firefox.dev/41wL4Na

While inspecting it it looks like it wait for exactly 9 seconds in a call to retrieve clipboard contents, but that's just what it looks like and I could be wrong, hope it helps!

Try downloading Firefox from Mozilla and run it from the folder and see if you have the same issue. https://www.mozilla.org/en-US/firefox/all/#product-desktop-release

X11 or Wayland? I don't have this issue.
