Support for extensions using XUL/XPCOM or the Add-on SDK was removed in Firefox 57, released November 2017. As there is no supported version of Firefox enabling these technologies, this page will be removed by December 2020.

Add-ons using the techniques described in this document are considered a legacy technology in Firefox. Don't use these techniques to develop new add-ons. Use WebExtensions instead. If you maintain an add-on which uses the techniques described here, consider migrating it to use WebExtensions.

See if your email has appeared in a company’s data breach. Facebook Container. The Firefox address bar displays the URL (web address) for the page that you are visiting. When you type into this field to enter a URL or search term, Firefox remembers the pages that you have visited and shows page suggestions in the address bar drop-down, such as sites you've bookmarked, tagged, visited before, or have open in tabs.

Starting from Firefox 53, no new legacy add-ons will be accepted on addons.mozilla.org (AMO) for desktop Firefox and Firefox for Android.

Starting from Firefox 57, only extensions developed using WebExtensions APIs will be supported on Desktop Firefox and Firefox for Android.

Even before Firefox 57, changes coming up in the Firefox platform will break many legacy extensions. These changes include multiprocess Firefox (e10s), sandboxing, and multiple content processes. Legacy extensions that are affected by these changes should migrate to use WebExtensions APIs if they can. See the 'Compatibility Milestones' document for more information.

A wiki page containing resources, migration paths, office hours, and more, is available to help developers transition to the new technologies.

Autocomplete is a default feature of most modern web browsers. It anticipates what you are typing and suggests a word or phrase based on the activity of other users and your history. If you press Enter, the application automatically completes your typing with the remainder of the suggested text. For example, if you type goog in your browser's address bar, the browser may suggest google.com by displaying the letters you haven't typed yet. If you press Enter, the browser goes to that website.

To enable or disable autocomplete in your browser, select your browser from the list below and follow the instructions.

By hitting Enter on an autocomplete suggestion in the address bar, your browser takes you directly to the website. If you are skeptical about a URL, use the search bar instead, which offers a preview of the website through your search engine.

This page only shows you how to toggle the autocomplete feature on and off. For steps on deleting autocomplete history in the address bar, see: How do I clear my address bar history? and How to delete autocomplete history.
