A recent design idea from Mozilla had eliminated the browser's title bar for the more nearer firefox 3.7 mockup. This was replaced by two drop down menu buttons on the right of the new browser...the same that Google Chrome has natively since its debut.

Mozilla says the advantages to this is that it saves vertical space and removes visual complexity.
On the other side, it is new and a bit different and might confuse people who look for the usual File and Edit Menus. Also, the users see a part of the original title of a page at any point of usage.
For Firefox, putting tabs on top meshes conceptually with Electrolysis, aka Content Processes, an under-the-covers change that will make each tab a separate computing process. That carries potential performance, stability, and security advantages, but requires more memory.
The Firefox 4.0 mockups also show a combination button to the right of the address bar that changes behavior depending on what the browser is up to. The button can be used to start loading a page whose address has been typed, to stop loading if it's in the process of doing so, and to reload it if it's finished loading.
An example of Chrome's latest interface.
