Display Loading Progress in Address Bar

I’m sometimes astonished that I never heard about a Firefox add-on before. Fission is one of those add-ons that add a real cool effect to Firefox. It displays the loading progress in the address bar of Firefox which means that it becomes more visible this way.

The display effect itself looks nice as well and can be customized further. The transparent color that is used to visualize the loading progress can be changed and an image can be used as well. Instead of using the full address area users can opt to only use the right side of it.

I prefer to use the full address bar location though because it does look nicer and it is at the same time easier to spot.
