Firefox Development Edition added new features

Just removed 3 plugins from my dev Firefox we do not need anymore! Just press F12 and hit the settings button. At the left bottom, you see some amazing options, like: Colorpicker, Ruler, Screenshot. Another interesting thing ist the "Scratchpad" a JavaScript console, who can store and run JS snippets.

The activated tools are now available at the top right.

Typesetter aka gpEasy - Remove user lock

Simply navigate to your main directory, open the "data" folder, and delete the temporary "lock_...." file.

Adaptive background (color taken from an image via JS)

Take a look at this amazing thing. Love it.

The library take´s the "primary color" of an image, and set it to the image container as background color. Similar to the tv technique "Ambient Light".

Webfont "Amiri" wrong underline position

In a current project we used the beautiful looking font "Amiri". After hovering the first link, i saw the underline appearing way too to far at the bottom.

As we can´t fix this via CSS, i modified the font with FontForge. The result is called "Amirifix" and is attached to this post.

Amiri is an Open Font by Khaled Hosny & Sebastian Kosch.
