I posted a question of the forum, received a reply, tried to fix ff4 as was detailed in the reply, to no avail. Nothing suggested worked. So, rather than deal with a bad update, I want to revert to FF3.6 that worked fine. In my control panel it only shows FF4. If I uninstall it, will I be reverting to FF3.6? and if not what can I do to get back to FF3.6? Secondly, the user name and password I used when I registered several days ago, was not recognized today. So I created a new registration in my wife's name. This has enabled me to post this. Talk about frustration!!!
