Speaking of stores, there’s also Obtainium if you like living on the edge. It can pull directly from GitHub releases, which may or may not be desirable for different people.
Another obvious one is Firefox or its siblings Mull & Fennec, with their add-on support for a better browsing experience.
There’s also system-wide ad/tracker blocking solutions. I don’t actually have a recommendation on this as most of them share each other’s blocklist anyway.
