Firebug, turned out to be a real bug

Firebug, an addon for the popular web browser firefox became a pain in the a** once at work. It helps you to monitor HTTP request - response, Web Design layout etc. We were trying to make certain changes in our javascript file and review the changes. Clear the private data ( Ctrl-Shift-Delete), restart the browser, we tried almost everything . Later on after breaking head for sometime, we found out that firebug maintains its own cache of all the images, js and other component files being loaded that needs to be cleared in the console and the net tabs.
So folks, if you use firebug with firefox , better be watchful else keep scratching your head. :)
