Install the Adobe Acrobat Extension Manually

Since newer browser versions may not automatically integrate the Acrobat plugin during software installation, you can add it manually from the browser's official web store.

Modern versions of Chrome and Firefox use their own built-in PDF viewers by default and have deprecated older plug-in architectures. To restore Adobe functionality in your browser, you must install their modern browser extension directly from the add-on store.

1
Open your browser's extension store

Navigate to the Chrome Web Store or the Firefox Browser Add-ons page, depending on the browser you are currently using.

2
Search for Adobe Acrobat

Type 'Adobe Acrobat' into the search bar and locate the official extension provided by Adobe.

3
Add the extension

Click 'Add to Chrome' or 'Add to Firefox' and accept the required permissions to install the tool into your browser.

Frequently Asked Questions

Why are my PDFs opening in Chrome instead of Adobe Acrobat?

By default, Chrome uses its built-in PDF viewer. To change this, go to Chrome Settings > Privacy and security > Site Settings > Additional content settings > PDF documents, and select the option to download PDFs. They will then open in your default desktop PDF application.

Can I still use the old Adobe Acrobat plug-in in Firefox?

No, modern versions of Firefox have dropped support for NPAPI plug-ins, which includes the older Adobe Acrobat plug-in. You must use the modern Adobe Acrobat extension or rely on Firefox's native PDF viewer.

What should I do if the newly installed extension remains disabled?

Go to your browser's extension manager (type 'chrome://extensions/' in Chrome or 'about:addons' in Firefox into the address bar) and manually toggle the switch next to the Adobe Acrobat extension to enable it.
