Reload web pages with Firefox add-on

I have found one of the best Firefox add-on for eBay it’s called Reloadevery 2.0. As the add-on page says it."Reloads web pages every so many seconds or minutes. The function is accessible via the context menu (menu you get when you right click on a web page) or via a drop down menu on the reload button." Is great for watching eBay auctions. You can get it at this link  ReloadEvery :: Firefox Add-ons
