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

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!

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...).

Works just fine

Excellent addon for not only adding your own search engines to Firefox but also for backing up and importing them (whenever you move to a new PC or after a format). Thanks Dev!!

Tip: when exporting your search engines, it asks you to locate the "search.json.mozlz4" file.
This file can be found if you:
type Run in the Start Menu,
open the Run app,
then type %appdata% which opens your user folder,
then open Mozilla / Firefox / Profiles / xxxxxxxx.default-release
(xxxxxxxx will be a bunch of random numbers and letters)

I usually create a shortcut of that last folder and place it on my desktop, then hit Browse from this addon and double click the shortcut to get there. Easy peasy.
