- Firefox 3.5 adds support for the HTML 5
audio and video elements. - Offline resources in Firefox
- Firefox 3.5 now fully supports the HTML 5 offline resource specification.
- Drag and drop
- The HTML 5 drag and drop API allows support for dragging and dropping items within and between web sites. This also provides a simpler API for use by extensions and Mozilla-based applications.
Newly-supported CSS features - Downloadable fonts support
- The new
@font-face @rule lets web pages provide downloadable fonts, so that sites can be rendered exactly as the page author expects. - CSS media queries
- Firefox 3.5 now supports CSS media queries, which enhance support for media-dependent style sheets.

::before and ::after pseudo-elements have been updated to full CSS 2.1 support, adding support for the position , float , list-style-* , and some display properties. opacity - The
-moz-opacity Mozilla extension to CSS has been removed in favor of the standard opacity property. text-shadow - The
text-shadow property, which allows web content to specify shadow effects to apply to text and text decorations, is now supported. word-wrap - This newly-supported property lets content specify whether or not lines may be broken within words in order to prevent overflow when an otherwise unbreakable string is too long to fit on one line.
-moz-box-shadow -moz-border-image -moz-column-rule -moz-column-rule-width -moz-column-rule-style -moz-column-rule-color -moz-column-gap - Firefox 3.5 adds support for these Mozilla extensions to CSS.

New DOM features - Using DOM workers
- Firefox 3.5 supports DOM workers to allow easy multi-threading support in web applications.

canvas elements - Canvas elements now support the HTML 5 text API.
