实现了新的<main>元素(bug 820508).

-moz-user-select属性的属性值在设置为none时和设置为-moz-none时效果等同于,这样才能让Gecko和其他内核WebKit(Chrome, Safari),Presto (Opera)以及Trident(Internet Explorer)中的表现相同(bug 816298).
On XHTML content, the auto value of -moz-hyphens incorrectly applied hyphenation rules when the language was not explicitly declared. This is fixed by (bug 702121).
CSS属性-moz-orient现在支持新的值auto.当应用到一个<meter>元素或者<progress>元素上时,auto就等同于horizontal(bug 835883).

更新CSP实现到最新的CSP规范1.0(CR):
- Support for the spec-compliant Content-Security-Policy HTTP header (in addition to the experimental X-Content-Security-Policy) has been added (bug 783049). Note: the patch for this new header landed in Firefox 21, it is disabled on builds (bug 842657).

FUEL applications cannot use the Livemarks service anymore (bug 834492). The Livemarks service is deprecated and phased out in favor of the new async interface.
History API saw numerous deprecated API being removed:

  - nsIFaviconService::setFaviconData
  - nsIFaviconService::getFaviconData
  - nsIFaviconService::getFaviconForPage
  - nsIFaviconService::setAndLoadFaviconForPage
  - nsIFaviconService::getFaviconImageForPage
  - nsIFaviconService::getFaviconDataAsDataURL
- Replaced by mozIAsyncLivemarks:
  - nsILivemarkService::*
  - PlacesUtils.itemIsLivemark
  - PlacesUtils.nodeIsLivemarkContainer
  - PlacesUtils.nodeIsLivemarkItem
- Removed only third argument:
  - PlacesUIUtils.showBookmarkDialog
- No more implemented by Places, use mozIAsyncHistory instead:
  - nsIGlobalHistory2::addURI
  - nsIGlobalHistory2::isVisited
  - nsIGlobalHistory2::setPageTitle
- No more needed, use onDeleteURI or onItemRemoved:
  - nsINavHistoryObserver::OnBeforeDeleteURI
  - nsINavBookmarkObserver::OnBeforeItemRemoved
- Never implemented properly:
  - nsINavHistoryFullVisitResultNode
- Deprecated, use mozIAsyncHistory::updatePlaces instead:
  - nsINavHistoryService::AddVisit
