A dot appears as i click on link-UI issue

Firefox- windows-XP- A dot is appearing as you click on like link.

1) When i Log in the si开发者_JAVA百科te, 2) Enter search criteria, 3) Now click on "Like" link, Result:-a dot is appearing only at the time of liking the response.

Its an UI issue, dot appears only when the link is clicked i.e when focus is on the link. Can anyone suggest?

It's possible that this is an outline which appears by default in Firefox when focusing on the element. If so, this CSS might be what you are after. As Jon says, though, it's impossible to say without a link or some code at least.

:focus, :active { outline: 0; }
