I have downloaded firebug from this page:

(I use Firefox), but I don't know how to start using it - no icon on the desktop, no changes on the Firefox interface, so what should I do in order to start using firebug?

Also make sure you have restarted firefox first. – Sam Jan 6 '13 at 6:34

Since this is a firefox extension you have to install it into firefox. Cross-check in your addon settings.

Then you should see a small firebug icon in the lower right of your window in the status bar. Click it to open the interface. Usually F12 also opens it.

Firebug is a Firefox extension, not a separate application. If you load a webpage in Firefox, you can right-click on any element within the page and choose Inspect Element. The Firebug panel will open, with the HTML view highlighting the code for the element you right-clicked on. You can easily navigate the panel from there.
