It looks like Facebook may be testing a new design for their “Like” buttons and boxes found almost ubiquitously on websites.
I first noticed the new button design, which looks a lot more like the social buttons offered by Twitter, Google Plus an others, while visiting Nothing Serious using Firefox. I still get the same design in other browsers and in Firefox on my other machines.
The new design features the Facebook logo to one side, followed by the word like, all in a blue container with the likes above. As I said earlier this brings Facebook’s button design on par with those of other providers.
As you can see from the image below, the design is also being tested on other Facebook widgets such as the “like box”.
