Although settings for changing what Google stores is included, what is neglected in the above article is how to reduce the amount of data stored by Facebook. The first step is an ad-blocker extension. However, that isn't all. I see friends, people I have personally known for many years whose posts are "Public", meaning anyone can see them. The suggestions in this older article are still relevant, although I personally wouldn't use "Everyone" in the "Privacy Settings and Tools section: How to Lock Down Your Facebook Account For Maximum Privacy and Security |.
Another tool is F.B. Purity which helps to clean up and customize Facebook:
F.B. (Fluff Busting) Purity is a Facebook customizing browser extension. It alters your view of Facebook to show only relevant information to you. It lets you remove the annoying and irrelevant stories from your newsfeed such as game and application spam, ads and sponsored stories. It can also hide the boxes you don't want to see on each side of the newsfeed.
F.B. Purity is compatible with Firefox, Google Chrome, Edge, Safari, Opera and Maxthon, running on Windows, Mac, Linux etc. For Microsoft Edge, there is an extension in the Microsoft Store. To use with Pale Moon, it is necessary to install the Greasemonkey script version but it works great.
I personally use DuckDuckGo for any web searches, and tend to switch between Pale Moon and Brave for any web browsing. I've heard that ProtonMail is a good alternative to GMail and Outlook if you're concerned with privacy.
