What is this extension good for?

It allows setting a specific searXNG instance as your default search engine in Firefox.

What is searXNG?

SearXNG is a free internet metasearch engine which aggregates results from various search services and databases. Users are neither tracked nor profiled.

For which instances do extensions exist?

For some reliable instances (see https://searx.space/) that exist for a longer time and are somehow reliable (see https://github.com/ndsvw/SearXNG-Instances-Age#output).

Is this the OFFICIAL extension for instance XY?

No, the extensions have not been built by the instance owners themselves. The extensions are built based on a common source code that allows generating Firefox extensions for searXNG quickly.

Why not creating one single extension for all searXNG instances?

Because Firefox does not allow a dynamic search engine host that can be modified by the user. It has to be static when the extension is built. 🤷🏻

Does it work for Android, too?

No. You need to do it manually on Firefox on Android... The Mozilla documentation explains how to change the search engine

The "Search string URL" needs to be set to {instance}/search?q=%s, where {instance} needs to be replaced with the actual instance domain name, e.g. searx.be/search?q=%s.

The "Search suggestion API" field is optional. If you want to set a value, please fill in https://{instance}/autocompleter?q={searchTerms}, where {instance} needs to be replaced with the actual instance domain name again.
