Finally found the one addon that works, Thank You for making this.

Awesome extension, quite thoughtful with solid OpenSearch implementations searching the web should become easy straight from address bar.
A sync feature with Google Drive/OneDrive would be nice addition (possible to go cross-browser too)!

Great extension, in so far as it is needed.

Absolutely demential that I have to use an extension to get this basic feature though. At this point I just stick with Firefox by inertia.

Работает как часы! Смог наконец-то понадобавлять нужные мне системы поиска, которые Firefox по умолчанию за таковые не считает

UPD2025: В Firefox наконец-то добавили возможность добавлять поисковые системы более удобным способом, так что возможно вам это расширение уже и не потребуется. Тем не менее, мне всё ещё нравится, что может выгрузить их список отдельным файликом, так что для меня оно пока всё ещё актуально.

Nicely made and well documented. The best - perhaps only - "workaround" for the now broken open-search-xml engines

Unfortunately it doesnt work in newest FF on Mac (133.0, aarch64).

It's very useful!thank you for the great work!

Merely _defining_ a custom search with this addon is trivial.

But nothing in any bit of documentation I've been able to lay hands on tells me how to do any of the following:

* Add this custom search to Firefox' list of default searches.
* Replace ordinary Firefox search with my just-defined custom search in the search window.
* Use the newly defined custom search in any practical way whatsoever.

The newly defined custom search simply vanishes. Without a referent or any practial means of actually sending it the search query I type into the search bar.

The icon shows up nowhere. The name of the custom search shows up nowhere.

The documentation on github leads me down a blind alley.

This addon does not appear to have any practical use.

Easy to use and does the job. Thanks to the developer!
