I have a few important add-ons that will not work, yet, with Firefox 4. How easy is it for me to downgrade to 3.6 temporarily until these issues have been resolved?
I really need to downgrade to the previos Firefox version just until a couple of add-ons have been upgraded. How easily can I do this without losing my current settings?

There is no guarantee that the add-ons that currently do not work with Firefox 4 will ever be updated, they may have been discontinued.
To downgrade to Firefox 3.6 first uninstall Firefox 4, but do not select the option to "Remove my Firefox personal data". If you select that option it will delete your bookmarks, passwords and other user data.
You can then install the latest version of Firefox 3.6 available from http://www.mozilla.com/en-US/firefox/all-older.html - it will automatically use your current bookmarks, passwords etc.
To avoid possible problems with downgrading, I recommend going to your profile folder and deleting the following files if they exist - extensions.cache, extensions.rdf, extensions.ini, extensions.sqlite and localstore.rdf. Deleting these files will force Firefox to rebuild the list of installed extensions, checking their compatibility, and reset toolbar customizations.
