Are you bored of seeing the same old Gmail interface, here’s a Gmail design from Globex Designs called “Gmail Redesigned”, which reformats the whole Gmail display into a darker, more beveled design, leaving almost no design element, not even the loading message, as it was before (See the pic on right). The author is in the process working on this style almost daily, so it’s advisable to update it regularly.
It’s currently tested in “New Version” of Gmail using English (US). Also, it doesn’t support the "Better Gmail 2" or the “Remember The Milk” extensions. Support for these extensions will be added in the future.
Installation: To install the program, first install Stylish, restart, and then install Gmail Redesigned. To uninstall it, in the Firefox menu click on Tools —> Add-ons —> Stylish —> Options, and delete the Gmail Redesigned item (or completely uninstall Stylish)
