Add-on summary
Add a custom search engine to the list of available search engines in the search bar and URL bar.
Your custom search engine needs a name and search URL. Additionally fields include an icon, a suggestion URL, POST query parameters, the input encoding and a description.
Icons can be selected from your local computer or specified as an URL pointing to an image.
The extension UI is accessible via a button right next to the URL/search bar or the options in about:addons.
Due to a technical limitation with Firefox WebExtensions, all data entered when creating your custom search engine is uploaded to paste.mozilla.org.

this is the oldest (longest-used) add-on in my Firefox which is still installed.
I remember having a bliss to use this add-on instead of manually editing XMLs and starting a local web server so Firefox recognizes them.
I don't have it enabled all the time but from time to time I still enable it to add a search engine. A shame this is a hassle to do in Firefox without, other browsers I use don't have such problems. Also it's sad there is no easy way to edit a search after it's added, without re-adding it with the edits.
