Dialog boxes with black background display text also in black on Firefox. Other softwares don't.

[Paco_at]

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
