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

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

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

Worked first time!! Amazing! I'd like to see on the "Add a new search engine" page a note against the "Search name" field that this is the 'Full name' of the search, and you go into the " about:preferences#search" page to add the @keyword in a separate step -- to remind me next time -- but it's easy enough to figure out; especially as, at least, Firefox makes it easy to remove mis-named engines! :-D

Just amazing. I'm coming from "Add custom search engine" by Tom Schuster, however, I find this extension more funcionality that I'm looking for (e.g. adding from site's search bar, exporting...).
