Status: VERIFIED DUPLICATE of bug 398928

(Firefox :: Toolbars and Customization, defect)

Description

[David Reitter]

User-Agent:       Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9) Gecko/2008061004 Firefox/3.0
Build Identifier: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9) Gecko/2008061004 Firefox/3.0

I can't drag Firefox windows with the mouse from anywhere near the back/forward icon.  It appears there is something wrong with its mask.  In most applications, one is able to drag the window on any toolbar background.

This is most relevant when, after switching from a two- to a one-display setup (taking the laptop home from work) only 10% of the Firefox window are visible on the right edge of the screen.  In that case, it is very difficult to grab the window and drag it over.

Other applications do not display this issue.

Reproducible: Always

Steps to Reproduce:
try to drag&drop a window (with toolbar visible), using the toolbar background area to the lower left of the "back" button.
Actual Results:  
window does not move at all

Expected Results:  
as in all other Mac applications

Isn't this normal due to Fitt's Law ? The edge of the button extends all the way to the edge of the window or screen. If your window is maximized, then you can just throw your mouse to the left hand side, without worry of "overshooting" the button. You can't grab a window so close to a button.

no, the clickable area of the button doesn't extend to the toolbar edges, and it shouldn't.  only the masked portion is clickable, and unfortunately a little bit more.

Clicks need to be passed down to the system so the user can actually move the window.

I don't understand your report.

I can't drag an FF3 (or FF2) window by anything but it's titlebar (the
top 22 pixels, containing the Close, Minimize and Zoom buttons on its
left).  This is true on all platforms (OS X, Windows and Linux).

I _can_ drag a window by its titlebar even if I click between one of
the buttons on its left (say between the Close button and the Minimize
button) -- which is (of course) just above the back/forward button.

steve, I think your "titlebar" is my "toolbar". 
Either way, dragging doesn't work if you've got the mouse cursor to the left of the leftmost icon. That region, albeit toolbar background, is dead.

The consequence is that it's extremely difficult to drag the window back into the screen once it's stuck on the right edge (off screen, mostly).

Let's call it by its correct name -- the titlebar.

A toolbar is something else altogether -- a "bar" containing icons
that (when clicked on) perform commands, open dialogs, or open menus.
By default Firefox (both FF2 and FF3) has two of these -- the
"Navigation Toolbar" just below the titlebar, and the "Bookmarks
Toolbar" just below that.

You mean to the left of the red Close button (in the titlebar)?

I can't reproduce this, either -- I have no problem dragging a window
by the little bit of the titlebar to the left of the Close button.

Thanks for the lecture.  Are you at all familiar with the UI of the latest version of the operating system that I am reporting this bug for?

No, I meant what I wrote.  To the left of the leftmost icon.  That is the "back" icon (with the tooltip "Go back one page").

You're supposed to be able to drag a window by clicking on the background of the toolbar (which is visually one unit with the title bar).  
In FF3, dragging by the top portion of this element (which you would call titlebar) works, while dragging by the lower portion (where the icons are, which we both would call toolbar) doesn't.  Right now it's actually anywhere, not just on the left edge.

If you try this out with another Cocoa app, such as Mail.app or Camino, you can see that dragging should work.
