If you downgrade to an earlier version you will have to go through the update process again. Much easier with incremental changes. What you see in Firefox 4 will probably last up to or through Firefox 7. The changes will probably take you 10 minutes plus perhaps 5 minutes to get the Google Toolbar working. Google Toolbar * http://kb.mozillazine.org/Problematic_extensions * https://support.mozilla.com/en-US/questions/837473 You can make Firefox '''Firefox 5.0''' look like Firefox 3.6.18, see numbered items 1-10 in the following topic [http://dmcritchie.mvps.org/firefox/firefox-problems.htm#fx4interface Fix Firefox 4.0 toolbar user interface, problems (Make Firefox 5.0, or 4.0.1, look like 3.6)]. ---- For those that really need an earlier version of Firefox, find your system and the Firefox version you want in releases, download and start the install. * ftp://ftp.mozilla.org/pub/firefox/releases/ :or with the latest of version 3 * http://www.mozilla.com/firefox/all-older.html : Note Mac OS X 10.4 user, and Mac OS X 10.5 users without Intel cannot upgrade to Firefox 4 or 5. When reinstalling Firefox from a download, Firefox must be down once the installation starts. When the installation finishes, don't let the install start firefox for you. Instead end the install and start Firefox in your normal manner, thus preventing creating a new profile which does not have your bookmarks cookies, etc (but your old profile would still be around and would).
