How can I tell which browser I'm using?

An easy way to identify which web browser you are using is by recognizing the header, or top of the browser. Compare your browser to the images below. Keep in mind that browsers may be skinned/ themed/ customized, and as such may not look exactly like the screens below.

Note: If your browser doesn't look like any of the ones above, please consult whoever installed the browser, or your computer's manufacturer.
