Can prefetching “mess” things up?
Since prefetching is basically the same as clicking on a link, and clicking on a dynamic link can perform some action such as “logging you out” or “emptying your cart”, only static content is prefetched by Fasterfox. On top of the Mozilla prefetching limitations which are outlined here: Mozilla Link Prefetching FAQ Fasterfox further limits prefetching such that only files with the extension .gif, .htm, .html, .jpeg, .jpg, .pdf, .png, .text, .txt, and .xml are prefetched. This should eliminate all possibility of Enhanced Prefetching messing things up, however, if you should notice undesirable behavior, please file a bug or email me. Users who are behind a firewall which monitors web surfing habits (such as users at work) should note that all links which are prefetched will appear to the firewall as though they were visited by you (even though they will not appear in your history file). These users may wish to disable prefetching by disabling prefetching in the “Fasterfox” tab.
