the new Firefox button comes from Microsoft Office.
the space between tabs comes from either Opera or Microsoft Office.
the tabs on top, which is only a possibility at this point, comes from Opera first, but was implemented by Google Chrome down the line.
the use of so much transparency in the menu may come from Microsoft Office or Chrome.
the non-flat buttons can come from Opera or Chrome.
the use of only three buttons on the left, however, comes from Chrome. it should be mentioned that Firefox is playing with the idea of getting rid of a refresh button on the left by building it into the location bar. https://wiki.mozilla.org/Firefox/Projects/3.7_and_4.0_Theme_...
just want to give credit where credit is due.
Not that its a bad thing. Throughout its history FF have taken design ideas from IE, Opera extensively. For all we know, FF most likely wouldn't even consider such a drastic UI change if chrome wasn't in the picture. FF UI changes has always been incremental and subtle.
I like the way a lot of the cruft from 1990s Windows applications is starting to disappear from programmes that really don't need it like modern browsers.

By doing this they have set trends in how browser technologies should progress and thus had an influence on their ability to implement "html 5" webapps in the future that work cross browser. It was much more than "check it out we put tabs in the title bar guys".
Chrome saved space by getting rid of the title bar (a bar that would just say "Chrome"). From these pictures, Firefox still has a whole bar that just says "Firefox." Why?
Mozilla, please allow us to place tabs on the Title bar!
And if you really want to blow Chrome out of the water, explore innovative vertical tab options. Tree style tabs is an immensely popular extension for a reason.
The screenshot mockups don't tell.
Again.
