How can I stop Firefox from suggesting I add a website's search option to my browser's search bar?
I find it annoying that on any site with a search function, the Firefox search bar suggests adding that search protocol. I simply want to use the search I've chosen, and I'm not interested in adding more!

Firefox displays the option if it finds a tag in the page advertising the availability of a search plugin. I don't see a setting to turn off the detection and simply ignore that tag. Maybe someone else is aware of such a setting, or an add-on.
Meanwhile, it is possible to use a custom style rule to hide that bar on the drop-down panel. For example:
#PopupSearchAutoComplete .addengine-item { display: none !important; }
You can apply custom style rules to Firefox's interface using either the Stylish extension or a userChrome.css file. I'm heading out for a bit but if you don't get a better answer and decide to try this approach, another volunteer or I can explain the steps.
