Yandex is my favorite search engine now, and mail service. Forget about google...

It does not work properly to add search engine functionality on Firefox for Android - even though it says that it is compatible specifically with Android. It installs successfully but does not add the intended functionality, unless I am not finding where to use it. Please add a better description of how to use it, or remove the flag that says it is compatible with Android until it can be updated to do what it says it does in the description. Thank you so much, developer. I took a look at your code and will update/fork it to fix the issue and get the search suggestion API feature added. It's not difficult to add the search engine manually, unlike what it says on your project Readme. Thanks.

Не появляется Яндекс в списке.

Откройте сайт-поисковик яндекс, выберите его в адресной строке и добавьте как поисковик. А расширение отстойное

Popularization of a resource owned by a terrorist state.

Просто работает

Напишите в адресной строке мозиллы ya.ru и правой кнопкой добавьте его как поисковик и затем в настройках выставьте его поиском по умолчанию. Всё и расширение не обязательно для этого.

Not sure about the negative reviews (could be the nafo-fans/hurting ukies), for me the addon works as intended
