I addressed this below, but I should probably repost it here. Here's my take on it:
When choosing search apps, it's listed as "Firefox Search". However:
* it was automatically installed on my phone because it was the only present search app
* it replaced the nearly identical Google Search app, which I explicitly disabled
* At least on my phone, it only allows Google
* it doesn't conform to the Firefox data clearing
* it doesn't conform to the Firefox search engine preference
As far as I can tell, "Firefox Search" means "Google Search hooked into Firefox".
To be fair, I noticed that app name difference only after posting.
