Weird black circle in firefox

When I hover my main navigation to get my secondary navigation, 3 of the 4 images have a black circle on them, in firefox.

Never seen anything like this before, trying to google it but coming up pretty short of luck.

Well, I can’t see 'em.

Sorry, I meant to include one and forgot. Here you go:

It’s hard to see if you don’t highlight everything since they are black, but I noticed it originally because it was covering part of the first image.

I can’t see any circles - do you have a screenshot?

Ah, thanks! (by the way what you said yesterday worked I just didn’t wanna revive the topic)

It’s the list bullet on the nested ul.

Remove it like this:

#navbar ul{list-style:none}
