Review: Firefox 1.5, Thunderbird

Most browser users are familiar with this situation: You load a page in the browser, then click a link that takes you to a new page, and then return to the original page -- and you have to wait for the browser to render the page that you were just looking at.

Firefox 1.5 tackles this problem with a fast backwards and forwards navigation feature (bfcache) that speeds up browsing pages that have already been rendered. Previously, Firefox would save data for a page to cache, but re-render the page each time you navigated to it.
