Waterfox Private Search is a meta-search engine

isn’t a “metasearch engine” something that aggregates results from multiple search engines, like what SearXNG does? as far as I can tell, this one is a proxy that is going to let you choose between Google, Bing, Brave and Mojeek, and currently only the first one is available. it’s more akin to Startpage or Mullvad Leta, then.
