Another website that doesn't work in SeaMonkey, even w/ js enabled: chat.mozilla.org

The fact that they moved to matrix in the first place is bullshit, but the lack of an IRC tunnel is inexplicable, and the fact that they can't even provide a matrix webclient that is broadly standards compliant shows just how uninterested they are in user interface/support...

Matrix, where actually the only supported client is "Element"

(every single client I've tried for Matrix has been pure disappointment)

might as well rename the entire network to Element

tomman: matrix is everything xmpp promised to be except totally crap.
