Must have, really useful. But for some reason I can't add Bing, the magnifying-glass with the PLUS sign "add Bing" option just wont appear. Haven't had issues with any other search engine though. I'm using Firefox ESR.

Worked perfectly. Thanks! (PS use SearX!

It should be built in to firefox. Great and easy to use addon.

This is an elegant add-on that does what it should, with a minimum of clutter.

I'd like to submit a feature request (at the risk of adding clutter...). Currently, when a search string contains multiple words, the add on substitutes plus signs for the spaces between search terms. This works for most sites, but some require space characters (or %20) instead. It would be great to have an advanced option to choose which of these, or a custom character, is included in the string, on a per-site basis.

Thanks for a great add-on!

Very useful extension! I like to use it)
Очень полезное дополнение (реализует то, что по идее можно сделать функцией по умолчанию), просмотрел исходный код, ничего подозрительного не нашел.

Does exactly what it says, and does it very well. How this isn't a built-in feature of Firefox in 2021 boggles my mind.

Great, should be a default option in Firefox.

Could be more intuitive, but it works great.
