火狐4.2最快这个月的13号到15号发布

1. Tab multi-select similar to a feature that has recently become available in Chrome nightly builds (Chromium) as well. Users can simply select more than one tab and close or move them – or convert them in app tabs.

2. There will be a new tab page (no public mockups yet)

3. Add-ons will get standardized toolbar support

4. There will be a file upload indicator

5. The Home button will completely disappear. Instead, Mozilla will be adding a permanent Home app tab. This appears to be an evolving feature and Mozilla is exploring ways how to get rid of the home button, while not damaging the usability of the browser.

6. In-browser preview: Firefox will also get an integrated PDF viewer (like Chrome) and will extend this capability to more popular file formats, including MP3.

7. Taskbar web apps: We have discussed this feature already previously, but have not seen any more developments around it. Tabs will get their own context menus that can be configured by website owners. Websites will act much more like traditional apps and core features as well as navigation items will be accessible via the site tab.

8. Identity management: We have also written about this feature before. Firefox 5 will be able to keep you signed in to websites via an integrated identity manager and even support multiple sign-ons at the same time.

9.  The sharing features appears to be the big deal in Firefox 5 –  there will be a new paper plane logo in the URL bar that provides access to your social media accounts, such as Facebook, Twitter and we assume other services such as Reddit, Digg or StumbleUpon as well. You can add social accounts and “share” websites directly from your URL bar. there is no need for clicking a “Like” button.
