Очень помогло

This expansion is killer, it's simply brilliant. You can modify the search engines as you wish. It works really well, it's very practical.
Thank 🙏

It's insane that this extension has to exist at all but I'm really glad it does as it at least provides a way to edit Search Engines. Works like a charm.

Плюсы: позволяет переименовать custom search engines. Что и требовалось. Минусы: порядок таковых в открываемом xml не соответствует порядку в браузере, что при десятках позиций может затруднить поиск. Нельзя изменить / добавить иконку к custom search engine. Не изменить цветовую тему редактора — в текущей выделенный текст почти неотличим от невыделенного текста.

Thanks for this extension. Because they use a proprietary variant of json.lz4, and how rarely I need to modify the search provider, I had to figure it out more than once. This extension should never be deleted as it serves as an example. You are far too kind in your assessment of Mozilla's practices here.

Works

Works like a charm! Just follow the simple instructions.

Please fix the add-on is not properly saving to mozlz4. Other than that works great.

extremely useful for adding svg icons with data URLs to search engines. such a great extension.
