Could someone explain me the difference between these two entries: browser.sessionhistory.max_entries browser. sessionhistory. max_total_viewers

The descriptions found are not clear, especially for the second one. Thanks!

http://kb.mozillazine.org/About:config_entries

browser. sessionhistory. max_entries Integer The maximum number of pages in the browser's session history, i.e. the maximum number of URLs you can traverse purely through the Back/Forward buttons. Default value is 50.

browser. sessionhistory. max_total_viewers Integer Determines the maximum number of content viewers to cache for "bfcache" (fast back/forward navigation). Default value is -1 (calculate based on available memory). All values less than 0 are equivalent. Note: Firefox 1.5 and above only. Supersedes browser.sessionhistory.max_viewers.

browser. sessionhistory. max_viewers Integer The number of content viewers to cache for "bfcache" (fast back/forward navigation). Default value is 3. Note: Deer Park/Firefox 1.5b1 only. Functionality has been replaced by browser.sessionhistory.max_total_viewers.

Thanks but, with all due respect, this is what I've found on FF support and other sites. I would like to understand what does that mean from a practical point of view in the operation of FF (i.e. pushing buttons, clicking, etc.) I'm not an expert, this: "Determines the maximum number of content viewers to cache for "bfcache" (fast back/forward navigation). ..."means nothing to me. Thanks.
