Poorly support. Author will close your issues and ignore errors. It allows you to use invalid (unsupported by firefox) image formats.

This is awesome! I missed Chrome's search engine handling when I migrated to Firefox and this extension has filled the void perfectly. It also shows that even such a simple extension can be really pretty! :)

Was great when it worked. Nowadays, I get an error each time I try to add a new search engine: "Firefox could not download the search plugin from:
https://file.io/XXXXXX". I have switched to the "Search Engines Helper" which also uses file.io, but works fine on my system.

UPDATE: in response to dev's question: I can visit that file.io page with no problem. The Search Engines Helper addon also uses file.io as yours does, but it works for me.

UPDATE 2: Note that I can actually manually access the file.io URL that the "download error" dalog gives me by entering it in the URL bar -- I see the source of the XML file. Hope that helps!

UPDATE 3: After updating to new version (1.8), all is working properly again, so I have revised my lowered rating to reflect my true opinion of this very useful add-on.

This is the simplest and also the best extension of its kind, and the only ready-made solution for custom search engines since pre-Quantum times. The icon feature is excellent. As mentioned previously, the ability to export settings would make this even better. Thanks for this solid add-on!

Perfect !

Love it! Life-saver

Doesn't seem to do anything.
There's no options button for it in the addon menu.
There's nothing in the search options.
How are you supposed to use this addon to add a search engine?
And why dafuq you don't tell us how?

For some reason, I had not seen the blue magnifying glass the first time around. This time it worked and I managed to add the search engine that other add-ons could not add properly.

Does what it says. Would be nice to have an export function too, for easy website implementation/AMO upload.

FOSS. It works in Mozilla Firefox 133.0 (64-bit) under Windows 10, but you have to enter everything manually, not visually, without using the keyboard, as is implemented in similar add-ons. Some sites are incompatible with such a search due to the replacement of the space character (%20) with the “+” character.

Currently broken: "TypeError: NetworkError when attempting to fetch resource.[Learn More]" when adding a new engine.

Does what needs to do pretty well except it doesn't support POST method for search engines like startpage.com for example.

Very simple to use and works perfectly.

Works exactly like I want! So flawless! I am picky because so many add-ons I have tried did not work as smoothly as I had hoped. This did the steps perfectly even though I was doubtful at first. Thanks Tom!
