Adobe Acrobat Create PDF extension is available only for Firefox version 73 and older.
Adobe has an existing add-on for Firefox (see the screenshot below) which provides customers an easy way to convert their web pages to high-quality PDFs that they can work with. When Firefox releases version 57, legacy technologies (like add-on SDK and XUL-based) will be phased out and only Web Extension API-based add-ons will be supported. Today, in advance of the Firefox release, Adobe has made a new Web extension available so that customers will have a seamless experience when working with PDFs from Firefox.
The new Firefox extension has additional capabilities that weren’t supported in the earlier add-on:
The permission dialogue box (see the screenshot below) is a standard Firefox pop-up menu that will be displayed for every Web extension that users install, regardless of the maker. This dialogue box aims to inform the user about the need for permissions for an extension to function properly.
The Acrobat Create PDF extension needs to access the web page to convert it into a PDF in Acrobat DC. The extension does not access or collect any user or profile data or any other Personally Identifiable Information (PII) data.
