Put my Firefox back the way it was I can't figure this new one out

Hi.

No one can put back any updates you made to Fx, though you may not have anticipated such an upheaval it is often a great idea not to allow automatic updates.

Going back to another version is one thing. Bookmarks are also kept in the Profile folder [bookmarkbackups] though you would have to work on that which you can read up on.

The front or home page can be set via Settings > Home and startup

If Firefox starts up after an update without your bookmarks and other settings, check whether your data is available in a different profile:

Inside Firefox, type or paste about:profiles in the address bar and press Enter/Return to load it. The About Profiles page will open. This page should list at least one profile and could list many.

The profile that Firefox is currently using will show:
This is the profile in use and it cannot be deleted.

Please do not delete anything here; don't use any Remove buttons.

Do you have another profile named default or default-longnumber listed on this page? If so, you can check whether it is the one you were using recently by clicking its Launch profile in new browser button.

If it isn't what you want, simply close that new window.

If it IS what you want, click the Set as default profile button for that profile on the about:profiles page. Firefox will use it automatically at the next startup.

Note: If your bookmarks are not available in another Firefox profile, see Recover lost or missing Bookmarks for other solutions.
