Firefox only

I recently heard (via Lifehacker) of this GreaseMonkey script that will optimize your Google Reader window to fill 100% of the available horizontal space. This works not only for wide screens, but for standard screens as well. In my experience, Reader doesn’t maximize its horizontal space by default, but this script modifies the style for each article to fill that space.

To use this script, you must have the GreaseMonkey add-on installed. Download the script here and add it to GreaseMonkey. Then enjoy the pleasure of reduced vertical scrolling.
