Facebook Android APP vs. Windows 10 Browser

In my Windows 10 browsers, I use Facebook Purity to organize my Facebook Web-page. I use AdBlocker for my Waterfox browser. Candidly, I see only a few ads via my Windows 10 browser.

How can I suppress ads on my Android APP provided by Facebook.

Should I switch to a web-based Facebook page and delete the Facebook Android APP.

Yup, been to settings and have disabled all that I could, but to no avail.

Any thoughts or suggstions?

Thanks
