Some websites' signin/signout pulldown now impossible to identify and access, because only bottom half of the Tabs field displays. Top half is always obscured by a white bar (see blue arrow in attached JPG screenshot).

i am running Firefox on a Windows 10 Dell G3 laptop. I wonder if this is a problem with settings or with Add-Ons?

Hi,

Does the problem persist if you run Firefox in Troubleshoot Mode?

This is coming from an outdated addon that's trying to show some message and fails, like: support.mozilla.org/questions/1584701

Thanks, that is the solution. I removed Adguard and problem gone.
