3. Click in urlbar
4. Press End key
5. Switch to the tab from Step 1 (click that tab OR press Ctrl+Shift+Tab)
6. Switch back to the tab from Step 2 (click that tab OR press Ctrl+Tab)

AR:
 When I leave the tab with long url (Step 5), the url is scrolled to the end. You can see word "end"
 When I go back to the tab with long url (Step 6), the url is scrolled to the beginning.

ER:  
 When I go back to the tab with long url (Step 6), url should be scrolled
 to exact place where it was when I left the tab.

Use case:
 There're many cases when I need to edit a long url (compared to urlbar). The simplest example is
  data: urls which I use as testcases to my 800+ bugs I filed about Firefox. Sometimes I need to
  switch to another tab to grab some string/url which I'm going to use in the long url.
 Caret is usually is already placed in the right place in the url. The only thing I need is to
  switch to another tab and grab a string. So when I go back, I expect is NOT to be extremely hard
  to find the exact place in url I stopped before switching to another tab.

 You can read about another use case in bug 1249330 (which is regression btw).

Note:
 I was surprised to find out that GoogleChrome actually does that with any scroll position of url

Mass bug change to replace various 'parity' whiteboard flags with the new canonical keywords. (See bug 1443764 comment 13.)
