I want to degrade my version of firefox to the previous version that I had because I don't like the new one, but don't know how!
I have the newest Firefox, but don't like it at all... I want to change it to my old version but don't know how at all!

What don't you like. Firefox is highly customizable and you may be able to customize it to meet your needs.
If you do not like the new UI, you can make Firefox 4 look and behave more like Firefox 3.6, for details see http://redherring2.wordpress.com/2011/01/17/firefox-4-restoring-firefox-3-ui
To downgrade to Firefox 3.6.* you can 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.
