We always say that the best feature of Firefox is the unrivaled customization the browser offers. Even if you don't like the UI and default look of Firefox, addons, themes and personas can change it. Accessing extension options in Firefox is cumbersome today. Firefox opens a separate addons page in a new tab to manage them. It takes several clicks to access extension options and then you have to close the Add-ons page every time. This is where an extension called 'Extension Options Menu' helps.
