   Test.

1. Load
https://example.com/browser/browser/base/content/test/redirect_bug623155.sjs#BG
   in a background tab.

2. The redirected URI is <https://www.bank1.com/#BG>, which displayes a cert
   error page.

3. Switch the tab to foreground.

4. Check the URLbar's value, expecting <https://www.bank1.com/#BG>

5. Load
https://example.com/browser/browser/base/content/test/redirect_bug623155.sjs#FG
   in the foreground tab.

6. The redirected URI is <https://www.bank1.com/#FG>. And this is also
   a cert-error page.

7. Check the URLbar's value, expecting <https://www.bank1.com/#FG>

8. End.
