But first, this does not appear to be a How To question. As such I can't give you a How To reply.
When FireFox updates it checks the add-ins and add-ons for compatibility so you will find toolbars to vanish and things to head back to stock settings.
For now, for today this will be how things have to work.
Last time I updated, Firefox seemed to take over my systems. The tool bars, etc.
I use att Yahoo and it was a real pain. Did I do something wrong or check the wrong box?
