(Talked about this at FOSDEM'09.)
KompoZer (which is based on Nvu code) is currently built using Gecko 1.8.1 ... and would like to upgrade to Gecko 1.9.1.
SeaMonkey(/Composer) v2.0pre is currently developed using Gecko 1.9.1 ... and would be interested in bug fixes and new features from KompoZer.
Verbosio: An Extensible XML Editor Architecture
might be of interest too !?
Forget about Verbosio for now, it's nowhere near ready.
Summary of EU MozCamp 2009 discussion:
KompoZer 0.8 should soon be available,
SeaMonkey 2.0 should soon be available,
after that, both teams should (be able to) work toward un-forking future KompoZer 0.9 and SeaMonkey 2.1 codes as much as possible.
As KompoZer's lead, I confirm I can start working on this as soon as bug 477845 is solved.
What's the status here?
Shouldn't this be closed as WONTFIX in favor of backporting Blue Griffin (http://bluegriffon.org/)? Development of KompoZer effectively stopped in 2011 (http://kazhack.org/?post/2011/06/13/One-Year-At-INRIA), which is now nearly five years ago. The last stable release of KompoZer was 0.7.10, released in August 2007.
Ian: If this bug is indeed WONTFIX, then the block should be removed from 256570, I guess.
