It's possible that this bug is filed already.  I couldn't find it though, and I
wanted to get this in while the steps are still fresh in my mind:

1. Make sure prefs are set to select tabs opened from history
2. Open history sidebar
3. Middle-click a link to open it in a new tab
4. _Immediately_ switch away from the just-opened tab.  You must switch away
while the content area is still gray, before the page background is painted.
5. Wait for the new page to finish loading (watch the load indicator in the tab)
6. Switch back to the new page
7. Try to scroll using arrows, tab, etc -- doesn't work

This bug is still present in Firefox 1.5.0.6 and 2.0b1. I noticed a slightly different approach for triggering the bug:

1. Go to http://www.google.com
2. Open a new tab and go to some slow site, e.g. http://sourceforge.net
3. Click a link and immediately switch to the first tab
4. Wait until 'Loading...' disappears on the second tab
5. Switch to the second tab and type some letters
6. Switch to the first tab and notice how the letters typed appear in the search field (that is, the wrong tab gets focus)

Could it be related to bug 314362?

Here's another set of steps to reproduce for what I think is the same bug (and I do a slightly more complex version of these steps every day):

1. bookmark a pair of tabs in a folder, with the second tab being
   https://lists.mozilla.org/admindb/dev-planning
2. open a new browser window
3. make the window small enough that
   https://lists.mozilla.org/admindb/dev-planning needs scrollbars
4. go to the bookmark folder made in (1), and select "Open All in Tabs"
5. once they load (and you're on the first tab), hit Ctrl-PgDn to select the
   second tab
6. click in the password field
7. type a password (incorrect is fine, although it also happens with the
   correct password)
8. hit Tab to focus the "Submit" button
9. in *rapid* succession, hit Space (to submit the form) and then Ctrl-PgUp to
   switch to the first tab
10. once the tab loads, hit Ctrl-PgDn to switch back to it
11. try using the arrow keys to scroll the page (either the invalid-password
    page or the list of moderation requests)

The arrow keys don't work, but they should.  (Note that find-in-page does work, though.)

My first patch to mozilla! Be gentle :)

With this patch, the 3 repros above (comment #0, comment #1, comment #3) no longer trigger this bug.

make sure browser remember & restore the correct focus

Obsoleting patch.
This causes a regression. Focus to elements within iframes are not restored.

Revised patch. Do not restore focus to elements, documents or windows that are detached.

make sure browser remember & restore the correct focus, v2

This isn't quite right.

This causes a regression. If the focus was on the url bar before switching tabs, we expect the url bar to get focus again when switching back.

Oliver, can you take another crack at this?

I was posting my comments at bug 311376 about loss of ability to scroll with the arrow keys, but was referred to this bug.

Steps to reproduce:
1. In about:config, set security.warn_submit_insecure to true.
2. Go to a page by submitting a form by hitting Enter twice (a Google search will do)
3. Note that you can't scroll vertically using the arrow keys. Clicking the page or clicking a link (to a page without frames) will not restore it.
4. Press ' and Esc to turn FAYT on and off.
5. Arrow scrolling works again.
