IE Tab was originally conceived by a Taiwanese medical student, Hong Jen Yee. He first developed the plugin and provided a simple demonstration page; he then released it to the forums of the Taiwan Mozilla community. Other Taiwan developers created an extension to facilitate the use of the plugin. With some instructions for XPCOM usage from Swiss Mozilla developer Christian Biesinger, the plugin and extension were integrated successfully, forming the prototype of IE Tab. The tool was initially released on mozdev.org and the MozillaZine forum.
The original developer, Hong Jen Yee, abandoned the project in 2006, but subsequent development has been carried on by Blackfish Software since 2009.
