No white lines...

Oh, something else: the white lines disappear when the browser window is resized or firefox is behind another window and brought to front. Something with redrawing?

I can't reproduce your case but I can reproduce a possibly similar case and that bug is a regression from Bug 177805.

I couldn't reproduce it either with Firefox full-screen, but with certain widths I could. So this probably happens when that width is odd or something like that... Could you try resizing your window and try to reproduce it?

Resizing the window doesn't help. But when I hover over the menus I see white lines and that is indeed caused by Bug 177805.
That these menus don't expand is Bug 382479.

It is easy to reproduce on this page: http://www.nu.nl/
as you can see on the screenshot.

I can't reproduce this anymore. Haven't seen these lines in a long time. Closing WORKSFORME.
