Opening a tab causes the scrollbar to grow a border

Thanks for your bug. What version of epiphany/ubuntu do you use? Is your window
maximized? Is the border drawed? Could you make a screenshot of the issue?

Confirmed with 1.9.3.1 with FF/Deer Park 1.5rc3 on dapper. Upstream already as:
http://bugzilla.gnome.org/show_bug.cgi?id=112291

Probably the same as: https://bugzilla.gnome.org/show_bug.cgi?id=123408

Or https://bugzilla.gnome.org/show_bug.cgi?id=123408

the upstream bug suggests that should be fixed in the current GNOME version

Almost there...

On Xfce4.8... and Epiphany 3.0.4 and Gedit 3.2.3, I cannot GRAB or DRAG the scrollbar with the primary mouse button. However, on a mouse button down along the right edge of the screen on a maximized Epiphany or Gedit window, the app will PageUp / PageDown depending on where I click (mouse down).

But the standard, expected full control of the scrollbar (i.e. drag) is not there.

On a long document, try scrolling to the bottom so it cannot page down. Now bring the mouse to the right edge, but somewhere along the drag handle.

Expected: Without pressing button, the scrollbar handle should darken slightly to show the mouse is over it. Then holding down mouse will cause drag handle to change color (e.g. darken more) and allow dragging.

Actual: Mouse over (at edge) does not change handle color. Drag handle does not change color. No dragging is initiated.

I should add that MIDDLE mouse click/drag works as expected and consistent with other apps: scrollbar is taken to the mouse position and drags as long as middle mouse button is held down.

(Running Xubuntu 11.10 Oneiric)

Sorry, comment 6 behavior is for when there is only ONE tab.

MULTIPLE tabs on Epiphany Browser 3.0.4 still has the no-op border: right edge mouse does not do anything with the scrolling at all.
