As time goes I spent quite time making the nsplugin work on 3.4 release. My fix was not optimal enough and it caused various regressions (like launching libreoffice everytime you launched browser and so on). In the end we managed to sort this out around 3.5beta2, it was a great shot, it worked perfectly with firefox-3.6 and we were happy.
But now with 3.5.4 it is building the plugin and it fail to register itself in the firefox-10 itself again. And with 3.6 release the plugin even fails to show up in the list of extensions in firefox.
As I never did working plugin for firefox I have no damn idea what is wrong in there. Same applies for the the rest of the developers whom don’t even care much about that extension. So if you are one of those who really like the idea of embedding your documents within browser and you understand (or at least want to work on) the plugins please poke me, or send me some patches right away. As of now you can grab even 3.5 code to hack on because the extension does not work anywhere.
Otherwise I will just drop the useflag from 3.6 on.
