Firefox caches information across all windows. This means that if you view a page in one window, no matter how many new windows you open up it will still be drawing from cache until it updates its view. The way to change how often it updates the view is described below:

*SHORT FORM*
Open firefox.
Type "about:config" in the URL window.
Change integer value of "browser.cache.check_doc_frequency" to 1.


*LONG DESCRIPTION*
To quickly and easily access a whole range of customizations and preferences for Firefox, simply open Firefox then go to your Firefox address bar and enter the URL "about:config" (without quotes), then press Enter. Instantly Firefox displays a large range of preferences sorted alphabetically.

browser.cache.check_doc_frequency [Integer] (3) - This setting determines how often Firefox checks for newer versions of the page you are viewing. This setting is similar to Internet Explorer's 'Check for newer versions of stored pages' setting.

If set to 0 Firefox only checks once per browser session; if set to 1 Firefox checks every time a page is viewed; if set to 2 Firefox never checks (i.e. it always uses the version stored locally in your browser cached); and if set to 3 (the default) Firefox checks at automatically determined intervals.

If you browse mostly pages which update their content often (i.e. daily) or have a lot of dynamic content you may wish to set this to 1 though it may slow down browsing speed, especially on slower connections. Otherwise the default of 3 is best for fastest browsing on most connections. You can experiment to see if 0 suits your needs, but don't use a value of 2.
