The latest version of Firefox is a welcome upgrade to most browsers. The reduced system resources load and improved rendering engine (making pages load significantly faster ) is well worth the upgrade by itself.
Firefox 3 looks slightly different than its predecessor (minor changes to the user interface similar to the minor changes from version 1 to version 2). However, in version 3 the browser buttons and window frames have been redesigned to conform with the look of whichever OS you’re running—Windows XP, Vista, Macintosh, or Linux.
