Why Firefox (Only)?

SynchroEdit currently works under Gecko-based browsers only (Firefox, Camino, Flock, etc.), which means it does not work for Internet Explorer users or Opera users. The reason for this isn't that we think these browsers are beneath contempt, but rather that SynchroEdit is based on a technology that these browsers do not support -- a technology that is described in the W3C specification for DOM Level 2.

The technology is called mutation events. Mutation events can be used to detect when nodes or node content is modified in a page, and this is more or less what SynchroEdit is all about. Thus, we are hoping that the developers of Internet Explorer will implement mutation events, and we are hoping that the developers of Opera will fix the bugs related to mutation events, and when this happens, we will be the first to cheer.
