Hello, we're sorry that this addon does not suit you but the search engine feature is advised on the description.

As for the search language, we're sorry that the settings were not obvious too. Qwant does handle over 20 different languages, and of course english is one of them.

The fact that you cannot revert your homepage is truly an issue and we've already asked Mozilla if the override of the homepage could be consensual, but as of today, if an extension wants to set the user's homepage, there is no other way than what we did, this is why we do provide another addon.
