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

[Lucian Branescu]

I've put that on hold for now. It's rather low-impact high-effort when
compared to userstyles and userscripts.

I'll try downloading the favicon with stuff in nsChannel, but I'm not
sure I can embed that in an SVG (especially since gtk's SVG support is
very bad).
