Never more firefox ...
... because when I open the following site
a mask appears asking for login, while using other browsers like chrome, edge, opera, this doesn't happen, why so with firefox ?
Ďalšie informácie o systéme

This is their fault. This image triggers the admin prompt: https://www.inmeteo.net/blog/wp-admin/images/w-logo-blue.png
They shouldn't use the image from the restricted admin area.
If you want, you can block this request in uBlock, the admin prompt won't show anymore.
Thank you for reply, so I ask you why this fault manifests itself only on firefox browser and not on the others ??
