- Product
- Adobe Acrobat DC, Chrome, Firefox
- Device & OS
- Windows 10
- Scenario
- Attempting to view or edit PDF documents directly within a web browser using the Adobe Acrobat extension.
- Observed behavior
- The Acrobat extension icon does not appear, and there is no disabled extension listed in the browser settings, even after reinstalling the applications.
Ensure your web browser is updated to the latest version and verify that your Acrobat DC installation is fully complete and activated on your Windows PC.
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.
Navigate to the Chrome Web Store or the Firefox Browser Add-ons page, depending on the browser you are currently using.
Type 'Adobe Acrobat' into the search bar and locate the official extension provided by Adobe.
Click 'Add to Chrome' or 'Add to Firefox' and accept the required permissions to install the tool into your browser.

Download the PDF and Open in the Desktop App
If the browser extension is incompatible or fails to work, downloading the PDF locally ensures you have full access to all editing features.
Handle PDFs Seamlessly with WPS Office

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.
