ShortcutKey2URL is a cool firefox add on which lets you open any website in firefox with a keyboard shortcut you specify.
The shortcut you specify to open the website URL will be of the syntax [ ctrl + Q + any key ] , just like in my case I tested ShortcutKey2URL and specified a keyword shortcut as Ctrl + Q + E
Three kinds of methods can be specified for the method of opening URL, like opening it in current active tab, new tab or search the previously opened tab.
