uBlock Origin works best on Firefox
uBlock Origin - An efficient blocker for Chromium and Firefox. Fast and lean. - gorhill/uBlock
UBlock Origin on Android in FF is a killer feature for the app! It's been such a blessing browsing what are usually ad-infested mobile blogs and sites. Adding ghostery to the mix is just :chefs-kiss:
Why do I need ublock origin AND ghostery? Should one of them be enough?
Who says you do?
You don't need both of them. I use ghostery in addition to uBO because it includes features like automated cookie consent banner management.
