Enhance Firefox with Custom Search Engine

Add Custom Search Engine is a Firefox extension that allows users to create and manage their own search engines within the browser. This tool enables customization of the search experience by allowing users to specify a name, search URL, and additional parameters such as an icon, suggestion URL, POST query parameters, input encoding, and a description. The user-friendly interface is easily accessible via a button located next to the URL/search bar or through the options menu in about:addons.

One notable aspect of this extension is its requirement to upload all data entered when creating a custom search engine to a third-party service due to Firefox WebExtensions' technical limitations. Despite this limitation, the extension provides a straightforward way to tailor search engine options to better suit individual needs, enhancing the overall browsing experience.
