I wondered why I cannot add eBay as a search engine. Turns out the name was already used internally some way even if I hadn't installed an eBay search. So "ebay" instead of "eBay" as search name worked but it would be nice if the user could get some type of feedback otherwise this is quite confusing.

Correspond à la fonction intégrée nativement dans Firefox mobile, fonctionne très bien !

Works great! It's odd something like this has to be done through an extension, but that's on Mozilla. The add-on itself works perfectly.

WORKS.....wow!!!

Simple and awesome should be a core feature. I found myself using custom search engines for more accurate seearch results when consulting API docs.

I was looking for something like this, but it would not allow using https://%s as the search url, so uninstalled. I think it was exactly what I was looking for, save that small validation done IMO wrong.

works like a charm. can add unlimited searches - facebook or intranet people search is priceless! thanks.

Still does its job on FF83. Thank You!

I really love this function. Back in the days where the search box was a default to firefox. I think 3 or few years back. It use to be "add-to-search". I am not sure if your the same developer. But non the less, thanks a lot

It's a must have extension. This should be a native function imho, but this extension make the work and make it very well. Thank you!!! :)

edit: figured it out, though seems quirky
Used to work now I get this: When I manually enter a search engine and press "Add custom search engine" I get sent to the "Adding a new search engine via the URL bar" page, showing how to add a search engine with the 3 dot menu, but the option in the 3 dot menu never appears for the sites im trying to add. just like the other guy, will also fix the rating if the issue is fixed.
