Do you have the same issue with Firefox in Troubleshoot Mode?

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

What Desktop? X11 or Wayland?

I don't have that issue with my distro nor Mozilla version of Firefox. see screenshot

Also checked in ESR and no issues for me.

a direction arrow is clicked

Which "direction arrow" specifically? Keyboard arrow keys? The small compass arrows? The arrow target placed in the environment? The arrow directions for a route?

jonzn4SUSE. Thank you for your responses.

Troubleshoot mode made difference, the problem prevails.

X11.

Haven't tried your 2nd suggestion as yet. I'll keep you posted.

zeroknight. Yes, the keyboard arrow keys. Using the compass arrows works OK.

Does it still happen with the flatpak package?
