Craptastic.. at least I now know what happened to our plugin. I inherited this browser plugin (and it's IE equivalent ActiveX control) and know next to nothing about FF plugin/Extension dev. Our brilliant over-lords axed the original developers rationalizing that all that would be needed was minor currency work. Can anyone else that's rewriting their plugin please outline what they intend to do to re-write their plugins now that the XPCOM API has silently disappeared and what sort of sizing I should estimate on our doing so? We used our plugin to do several things like a custom file picker, access/upload/read files from the file system. Any guidance would be greatly appreciated.
