Just upgraded to FF 4.0 . I had no idea I was about to embark an a new 'project' (learning all the changes and figuring out why my FF 4.0 does not look like the examples given). MOST IMPORTANTLY - I had no idea (I didn't say I was smart) that so many of my FF plug-ins would no longer function (like SEO quake). I want/NEED to return to previous version of FF unless someone can tell me my SEO Quake CAN work in FF 4.0 and also HOW to make it work. tia, semi-sunny
