I just removed the extension because Firefox now also natively allows to add custom search engines via the settings (see extension description).

Unfortunately, both available upload services of the extension are currently down, making the extension unusable.

However I always loved the extension and used it a lot over the past years so I wanted to leave a positive review as "goodbye".

Works great

Helped a lot when the browser native support hasn't come around, thank you!

It's pretty good

Today, I will uninstall this wonderful add-on as the latest Firefox versions now offer native support for adding custom search engines.

I want to thank the developer for providing us with an intermediary solution all this time. This is the power of the Firefox community!

works great, simple, greatly increased my workflow by adding a bunch of search engines, thanks to the author

めっちゃ助かった👏

Worked like a charm on zen for suggestions engine! Used for duckduckgo lite.

awesome addon. But it seems to no longer work? Fixing it would be really good
