It's the green parts that look white / grey. I believe it's more of an illusions - if you have something to contrast it with, such as the moon, you can start to see a slight green tint. The pink I saw last night was very noticeable though.
It looks like it's the addon's fault, and has already been fixed in the github version. It's also been abandoned, so it's probably not worth keeping around anyway.
It seems to be caused by the FediAct addon, which doesn't make any sense. Disabling the addon fixes the page without needing a reload, so it must be a CSS issue rather than an exception. Edit: it seems the addon is overriding the fadeIn keyframe, but it looks fixed in the github version.

My dad had this same issue. He spoke to IT, and they sent him a security key he could use instead. Ended up needing a new phone a few months later anyway though...
Is there anything missing from Best-Before? It may just be finished. There is no mention of anything obvious (such as a dependency on an API) that would cause it to stop working.
