Don’t want your IP address to appear on sites you visited?
By default, firefox will do something called link-prefetching:
Link prefetching is a browser mechanism, which utilizes browser idle time to download or prefetch documents that the user might visit in the near future. A web page provides a set of prefetching hints to the browser, and after the browser is finished loading the page, it begins silently prefetching specified documents and stores them in its cache. When the user visits one of the prefetched documents, it can be served up quickly out of the browser’s cache.
If you do not want it to do that (think about all the sites that pages refer to that you may never visit but will have your IP address in their access logs):
- type “about:config” into your URL bar and press ENTER
- search for “network.prefetch-next” and double-click to de-activate
