This has been one of my main arguments against the continuing trend of over-simplifying the layout
of the user interface on a browser. While you may be gaining a few extra pixels of display space for
viewing pages, by removing or hiding toolbars that some might consider surplus to requirements,
other aspects, such as deciding where to best place your Bookmarks, becomes a problem.
Anyway ... here how the setup of my current SeaMonkey installation usually looks . . .

On the far left of the toolbars, a UI element that's been around since Netscape 4.x, called "grippies".
Back then, you could click the grippies to hide any of the toolbars, or swap around their positions.
On SeaMonkey (since Mozilla Suite v0.x - 1.7) the swap around option is gone, the click to hide
option is still available. If I want to hide the Menu Bar, which is extremely rare, one click and
it's gone ... well, not so much gone, but folded away under the main toolbar . . .

Same applies to the Personal Toolbar (Bookmarks) and the main toolbar . . .

Click the grippies again to bring the toolbars back.
And just for the sheer heck of it, let's put the main toolbar buttons on the Menu Bar . . . !

(BTW ... Grippies are not available in Firefox, but AFAIK, can be added ... with an add-on.)

SeaMonkey = Swiss Army Knife: It's versatile, reliable, and contains useful tools.
Windows Internet Explorer = Old Swiss Cheese: Full of holes, and it stinks!
