Can we please talk about how bullshit this is? I love Mozilla and Firefox but it's not like there's a million lines of GTK code in there; what the hell constitutes 3 years of porting?
Also a good question: what does plugin-container have to do with GTK? Rather, what does NPAPI have to do with GTK that it cannot be built without linking to GTK2?
(at least that's what I've gotten from a brief look at the bug linked in the article)
