Last night Google decided to change some UI elements in its homepage. This time buttons changed, getting bigger and more squared. They also got a new style class -correct me if I am wrong but I don’t recall that class- for their buttons named “lsb” (i wonder if lsb means something). Moreover the text field above the search buttons got bigger. However these changes take place only with Firefox under Mac OS. Safari and Chrome don’t seem to be affected by these changes.
