<h3 id="User_experience">User experience</h3>
<dl>
 <dt>
  Location aware browsing</dt>
 <dd>
  If you choose, you may allow Firefox 3.5 to share information about your current location with web sites.  Firefox 3.5 can use information about the network you're connected to to share your location. Of course, it asks for your permission before doing so, to ensure your privacy.</dd>
 <dt>
  Open audio and video support</dt>
 <dd>
  Firefox 3.5 supports embedded video and audio using the open Ogg format, as well as WAV for audio. No plugins, no confusing error messages about needing to install something or other that turns out not to be available on your platform anyway.</dd>
 <dt>
  Local data storage</dt>
 <dd>
  Web applications can now use Web Storage's local storage capabilities to store data on your computer.  This is great for anything from site preferences to more complex data.</dd>

<h3 id="Security_and_privacy">Security and privacy</h3>
<dl>
 <dt>
  Private Browsing</dt>
 <dd>
  Need to use someone else's computer? Switch on Private Browsing mode and nothing will be recorded about your session, including cookies, history, and any other potentially private information.</dd>
 <dt>
  Better privacy controls</dt>
 <dd>
  The Privacy preference pane has been completely redesigned to offer users more control over their private information. Users can choose to retain or discard anything including history information, cookies, downloads, and form field information.  In addition, users can specify whether or not to include history and/or bookmarks in the location bar's automated suggestions, so you can keep private web addresses from popping up unexpectedly while typing in the location bar.</dd>

<h3 id="동작_속도">동작 속도</h3>

 <dt>
  더  빠른 JavaScript 동작속도</dt>
 <dd>
  "AJAX"에서 "J"를 뜻하는 JavaScript가 Firefox 3.5에서 새로운 TraceMonkey JavaScript 엔진을 이용해 더욱 빨라졌습니다. 웹 애플리케이션은 Firefox 3 보다 더욱 빨라졌습니다.</dd>
 <dt>
  더  빠른 페이지 표시속도</dt>
 <dd>
  "speculative parsing" 기술로 Firefox 3.5에서 웹 콘텐츠를 더 빨리 표시하게 되었습니다. 사용자들이 기술의 의미하는 바를 알 필요는 없습니다. 단지 "더 빨리 보여준다."고 알면 됩니다.</dd>
