How can I return to the previous Firefox - I hate the new version that just installed itself without asking and hides or deleted all the stuff I used?
Firefox deleted the old version which I liked and then updated itself without my permission to this new version which I hate. Why??? Stuff that was easy to access is now hidden or seems to have been deleted. This new Firefox is a backward step. How do I return to the previous version - other than via a System Restore - without losing all my bookmarks etc etc. And if I can do that, then how do I stop Firefox re-installing this horrible update?

Look here and see what you think of what I created as I wanted the previous version.
First, Type about:preferences#advanced<enter> in the address bar. Under Advanced, Select Update.
[v56+] Type about:preferences#general<enter> in the address bar. Select Update.
Select Never Check For Updates.
Also turn off Use a background service to install updates

If you still want to downgrade, look under; I still want to downgrade. Click the Directory of other versions and languages link. Look for the directory of the version that you want. But, remember that old versions may have security issues.
