Screen-readers, if the feature works properly, return

you wouldn't want a screen-reader to return you to a link.
Whether or not this can be done depends on how you leave the page.
Generally, you leave a page by following a link, button or clickable.
We rely on Firefox to return the scroll position and focus to the
correct position, which unfortunately seems to be a little broken. There
are a couple of reasons for this:
* The browser has a much better idea of history than does a screen
reader. The only way for a screen reader to uniquely identify a page is
to use its URL. In the web today, where many pages can have the same URL
but present different data based on other inputs such as post data and
cookies, this is not reliable.
* This information should be maintained for the entire browser session.
If you quit your screen reader, you should not lose your page position
for historically visited pages.
