Hi! To add BackToTopButton for yourself on specific wikis,
 * 1) open your profile and add   to the URL.
 * Link to page on OOAM, Link to page on SaS
 * 1) Then click on edit and copy and paste the BackToTopButton Personal installation code and save the page.
 * 2) That's it. The script may take some minutes to be loaded. Opening an article and adding   may help.

Note that this won't have an effect on SaS yet because of some changes to new wikis. This will change soon.

Help:CSS and JS customization might be of help, too, in particular Help:Personal CSS and JS and Help:CSS and JS pages.
