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

very useful addon

Excellent, thank you Sir!

Works great. Exactly what I needed!

This is my first ever review of an extension. This solved my issue. Thank you so much from the bottom of my heart.

Suggestion: If you could write a blog post with most popular search engines with their "search query URLs" or include a list inside the extension then that would be cherry on top.

It works great, love it so far!

I have a question. I came across a site where the search term doesn't appear in the URL of the search:

https://www.grailed.com

Any ideas how to add it to FF search engine? Or is it impossible to?

Amazing!!!

Great extension

还好，如果能把搜索栏和地址栏的搜索引擎分开就好了。

Well done Tom. Simple and effective for adding custom search engines. It's a shame firefox has made adding custom search engines so challenging.

I do wonder if this couldn't be a standalone site, though

Simple and effective
