[Bug 1576339] [NEW] Dialog boxes with black background display text also in black on Firefox. Other softwares don't.

[Paco_at]

Public bug reported:

When the mouse arrow is placed on any Firefox functionality (such as
thumbnail, link, bookmark, etc.) a small black box appears with text
explaining its purpose, which should appear in white. But the text
appears in black like the box itself, and is therefore unreadable. This
has begun just after a Firefox update. I guess it has to be a bug. I
don't have this problem with any other software. I checked with
LibreOffice, Mozilla Thunderbird, GIMP... and everything was normal.
Only Firefox presents this anomaly.

Best regards and thanks for your help
