[Sugar-devel] [GSoC] I need help for Webified - SSB activity favicons

[Lucian Branescu]

I've tried more methods from here
https://developer.mozilla.org/en/nsIFaviconService

getFaviconImageForPage() and getFaviconLinkForIcon() work and they
return URIs to the favicon. However, getFaviconData(
getFaviconLinkForIcon() ) still gives an exception.

I have looked at the URIs returned by getFaviconImageForPage() and
getFaviconLinkForIcon() and they're both the default favicon. This
means getFaviconData( getFaviconImageForPage() ) should work, but it
still doesn't. It also means that Browse doesn't collect favicons.


I could resort to getting /favicon.ico, but it's not very standard and
.ico is an annoying format. I would also not account for any <meta>
tags that may define icons. I was also hoping of using xulrunner's
image handling and get the base64 image from it instead of processing
an image file.
