User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:22.0) Gecko/20100101 Firefox/22.0 (Beta/Release)
Build ID: 20130617145905

Steps to reproduce:

0) I upgraded from 22 to 23
1) I selected text using shift and the arrow keys.
2) I copied the text using Ctrl+C.
3) I pressed the down arrow to move to the next line.

Actual results:

The cursor went to the end of the current line.

Expected results:

The cursor should have gone to the next line.  That's what it did in all previous versions of Firefox and it's what it does in every other text editing program I've used.

Example (cursor represented with a "|" symbol, selected text is that text between the "*" symbols)
State 1:
*asdf asdf asdf*|
sdfg sdfg sdfg

Action: press down key on keyboard

State 2 (what happens in >23):
asdf asdf asdf|
sdfg sdfg sdfg

State 2 (what happens in <22):
asdf asdf asdf
sdfg sdfg sdfg|
The new broken caret behavior was introduced by Bug 859088.
At least on wndows7, the behavior did not mach another windows application such as notepad.exe as well as Internet explorer9.
