What steps will reproduce the problem?
I'm not sure what is causing this, but firecookie seems to cause certain
web pages to reload when Back or Forward browser button is hit.  It does
not seem to happen on all pages, but seems easily reproducible on Red Hat
Bugzilla.

1. Visit any bug in Red Hat bugilla, no need to log in.  For example,
https://bugzilla.redhat.com/show_bug.cgi?id=1234
2. Verify that the cookie support is *not* enabled for the site in the
firebug's console.
3. There's a search text box on the top of the page.  Enter some random
text there, but do not hit Find.
4. Follow some link from the page, e.g. "Status:".
5. Hit back button to get back to the bug.
6. Observe the bug page to reload, once page is fully loaded, text in the
search text box disappears (not a big issue here, but as this resets forms,
it's quite annoying for pages with larger forms).
7. Disable firecookie, restart firefox, retry.  No page reload is observed
on Back / Forward.

What is the expected output? What do you see instead?
No page reload is expected when Back is hit.  Especially for sites, where
cookie monitoring support is not enabled.  Only workaround seems to be to
disable firecookie completely, and enable it / restart browser whenever
firecookie is needed to be used.

What version of the product are you using? On what operating system?
Firefox 3.0.5 on Linux, Firebug 1.3.0, Firecookie 0.7, no other extension
or local configuration.
