Firefox context menu and tooltip on wrong display?

[Roberto C. Sánchez]

I have recently decommissioned my main desktop workstation and switched
to using my laptop for daily work (rather than only when travelling). I
acquired a USB-C "docking station" and have connected two external
monitors (which were formerly attached to my desktop machine).

For some strange reason, when there is a Firefox window in the second or
third monitor context menus (from right-click) and tooltips do not
appear on the same screen as the Firefox window, but rather on the
primary monitor (the laptop integrated monitor). I tried searching, but
did not find anything recent or useful. Has anyone experienced this
same issue? I did not experience this at all on my desktop machine with
dual monitors (both the laptop where I am experiencing this and the
desktop where I did not experience this are running bullseye), so I am
curious if anyone has encountered this issue and if so how to resolve
it.

Regards,

-Roberto

This sounds familiar to me. I think I have observed this behaviour in the
past albeit never really reproducible. I thought it might be related to
starting on another screen than the browser is later actually used on, but I
could not trigger it with some simple tests here.

Back when it appeared I mostly did not bother trying to fix it because for
me it was only ever temporary in some situations and I could still control
the rouge menus with the keyboard and avoid moving the mouse cursor all over
the screens.

Just a datapoint, no solution though :(

Thanks, I tend to favor keyboard shortcuts, so this isn't as bad as it
could be for me.

It's too bad that there is not a straightforward way to pinpoint this.

For those following along, a little while ago the problem "went away".
That is, context menus, tooltips, and application menus now all show in
the expected places in Firefox. I really hope that this is not a
temporary situation and that whatever the problem was has just magically
resolved itself. :shrug:

And this morning the problem returned.
