Very nice, this addon helped me add SearX as a search engine. But I have a small bug: I cant paste urls into entry box from the Xorg primary clipboard.

Great tool! Many thanks. I would prefer to add a shortcut in the right click menu.

Doesn't work with FF 74.

Replaces the sorely missed capability Firefox used to have for adding a search engine based on the query URL. It also made it easy to add an icon for each search engine. The export function also works well. Unfortunately, the import function did not work for me, which is why I gave it 4 stars instead of 5.

win7x64 portable ff 66, addons: custom search eninge, context search, power search engine, bookmark search plus 2 also installed.
Search Engines Helper doesnt find favicon nor lets me add a search engine

A very useful addon.

Wonderful addon, works fine on quantum.
It generates a favicon automatically, and can backup into a json file.
Very impressive.

Great! I'll never use chrome again

I really like this addon! Just the one I need.

I was just looking at the new API to figure out how to rewrite my old add-on for Firefox Quantum, and came across yours. Uploading and then downloading the engine data doesn't look like the most elegant solution, but if this is really the only thing you can do now, what you gonna do ¯\_(ツ)_/¯

I'd consider checking whether the downloaded file is the same as the one you uploaded though, just to be sure that you are getting back the same thing and the file host is possibly not trying to do anything funny.

If you get an error message trying to add a search engine, verify that your employer is not filtering web access. :)

This add-on works great!

I love it, this is exactly the kind of add-on that I was searching for. This should be a default option in Firefox since it's really limited in the search engine department.

Thank you!
But after adding a search engine, it can be used only in the search bar?
It is not visible in the context menu. The thing is, I do not like the search bar, most of my searches are through selecting text then via right-clicking.
Will you implement this?

Não conseguia adicionar um mecanismo de busca customizado. Foi tiro e queda.
