|There are a number of areas where the performance of the [http://code.google.com/p/skia/ Skia] 2D graphics library is better than that of [http://www.cairographics.org/ Cairo], which Mozilla uses. Find them, and improve Cairo to match or exceed Skia's performance.

|Our rendering of CSS border corners is very sloppy, particularly when the corner is rounded or when two styles intersect. You could code [https://bugzilla.mozilla.org/show_bug.cgi?id=382721 dotted and dashed rounded corners] and/or improve their [https://bugzilla.mozilla.org/show_bug.cgi?id=19963 interaction with other styles], or work on making other joins prettier.

|The [http://en.wikipedia.org/wiki/JPEG_XR JPEG XR] compression standard gives us better compression than JPEG and other useful features like HDR and alpha channels. The library should be as similar to libjpeg as possible. It would be a "from scratch", freely licensed version and will need a student that is very comfortable with image compression and as has ideally written decompressors from scratch before.

|Develop the base for an add-on that creates a unified messaging UI inside browser tabs, following the [http://wiki.kairo.at/wiki/RMD RMD concept]. This should work with feed display and twitter integration in the beginning, but be extensible to be able to support other communications later.

| Implement server-side [http://en.wikipedia.org/wiki/OCSP_Stapling OCSP stapling]. (A patch for client-side OCSP stapling already exists.) Implement client-side disk caching of OCSP responses.

| Add DSA with key sizes > 1024 bits (bug 475578); modes of operation for AES: GCM (bug 373108), CTR (bug 373106), CFB (bug 358219); and TLS 1.2 PRF to the NSS softoken.

|There are no MediaWiki parsers for Python with extensible syntax or multiple output formats. We've felt this pain in SUMO, which uses MW syntax in its knowledge base, resulting in hacks upon hacks to support features like platform-sensitive content, inclusions, and templates. We propose to implement [[Community:SummerOfCode11:MediaWikiParser|a new MW parser]] that generates proper parse trees, allows for pluggable syntax, and does not drive callers out of their minds.

|A WebGL-based 3D visualization of a Webpage. The developer will create a WebGL representation of a web-page that allows a user to rotate the page through axes to see the nesting of DOM nodes within the document. Floats and absolute positioned elements will be visible above and below the page based on their z-index. Tilt will be used as an additional visualization tool as part of a next-generation web page inspector.
