Very Good !!!

Ey Mozilla, make this a built in feature. Thanks to for the development of this add-on tho.

Thank you, it works.

Absolutely love this extension. This should, imho, be a feature of Firefox itself. I fint this extension unskippable, for a lack of a better word.

It works! especially for those sites can't add a custom search engine by default, say the atlassian confluence cloud "Firefox could not install the search engine from: https://yoursite.atlassian.net/wiki/opensearch/osd.action"

Excellent - can add any search with a short keyword (wt for Wiktionary, for example, or 'ebooks' for 'Annie's Archive' to grab books).

It is crucial that this feature comes built-in with Firefox from the start. It should be considered an essential component of the browser.

goo d

works great. would be nice if it had a tutorial, but basically just replace the search term in the URL with %s

This addon works perfectly, but it's still so unbelievable that you need an addon for such a basic functionality which was available in earlier versions. And the WebExtensions update make it even more difficult so you'll have to upload your data to Mozilla when creating a cumstom search engine.
Firefox is evolving, just backwards.

Easy to use

其实在 about:config 里面修改 browser.urlbar.update2.engineAliasRefresh 为TRUE 就可以了
