Website - menus on the right side impossible to use on Firefox

[Zahari]

       
As the subject: the menus on the right side of the web map can't be used on Firefox (142.0.1 64-bit). 

On mouse-over, the menus open, but they close as soon as the mouse leaves the menu icon.

They're working as designed, for me, on the same browser version. Otherwise try the Blitzortung Map:

You running pop-up blockers, or third party extensions to block adverts, etc.?  Try turning them off on the map page.
