Hmmm, well, I'm at a bit of a loss, there. When firefox reloads your previous session, it should only be loading from a cache or offline session of sorts. Without seeing the site in question, I can't be sure, but I almost think that perhaps what you need is an add-on to prevent pages from auto-refreshing. It could be a case where the site you are talking about has code in the header that automatically refreshes the page, and then from there, it follows a meta redirect to the site home.
IF the site you are using is auto-refreshing by META code, then you may want to try this addon:

If that does not work for you, you might also try
NoScript. This is a much more 'intrusive' addon, however, it can block javascript redirects and auto reloads, and has a built in whitelist so that you can still allow these things on trusted websites.
There are about
:config options for auto-reload, however, I think that these make browsing quite difficult, as most websites utilize an auto-reload (such as banks, and shopping carts), and will no longer function correctly if they are disabled.
