- Product
- Adobe Acrobat / Mozilla Firefox
- Device & OS
- not provided
- Scenario
- Attempting to convert a webpage to a PDF document using the Acrobat extension within the Firefox browser.
- Observed behavior

Check for available updates in your Adobe Acrobat X Pro software, as Adobe occasionally releases official compatibility patches for newer browser versions.
Use Firefox's Built-in Save to PDF Feature
Bypass the broken legacy add-on by utilizing the native print-to-PDF functionality built directly into modern versions of Firefox.
Modern browsers have integrated robust PDF generation tools, making older third-party extensions unnecessary for basic webpage-to-PDF conversions.
Navigate to the webpage you wish to convert, click the Firefox application menu (three horizontal lines), and select 'Print', or simply press Ctrl+P on your keyboard.
In the Printer drop-down menu, choose the 'Save to PDF' option instead of a physical printer.
Click the 'Save' button, choose a destination folder on your computer, and save the generated PDF file.

Print via Adobe PDF Virtual Printer
Use the Adobe PDF virtual printer that was installed alongside Acrobat X Pro to convert the page.
Use a Supported Browser for the Add-on
If you strictly require the exact features provided by the Acrobat Create PDF add-on, switch to a browser version that maintains legacy plugin support.
Manage and Edit Your PDFs Effortlessly with WPS Office
When browser extensions fail, having a dependable desktop application for handling PDFs is essential. WPS Office is a powerful, lightweight alternative to Microsoft Office that includes a comprehensive built-in PDF toolkit for editing, converting, and managing your documents without relying on fragile browser plugins.
- 1. Download the Installer: Visit the official WPS Office website and download the free installation package.
- 2. Install the Suite: Run the downloaded file and follow the on-screen prompts to complete the installation.
- 3. Open Your PDFs: Launch WPS Office and drag your downloaded PDF files directly into the workspace to start viewing and editing.

Frequently Asked Questions
Why did Firefox 29 break my Acrobat Create PDF add-on?
Firefox 29 introduced a major interface and underlying code overhaul that changed how add-ons interact with the browser. Legacy plugins like Acrobat Create PDF 1.2 were not designed for this new architecture, causing them to stop working.
Can I reinstall the Acrobat add-on to fix the compatibility issue?
Reinstalling the add-on typically does not resolve the issue, as the root cause is a fundamental incompatibility between the new browser version and the old plugin code. You must wait for an official patch from Adobe.
Does Acrobat X Pro still work without the Firefox add-on?
Yes, Adobe Acrobat X Pro functions normally as a standalone desktop application. You can still create PDFs using the 'Adobe PDF' virtual printer from within Firefox or by directly opening files in Acrobat.
Are there other ways to save a webpage as a PDF?
Yes. Most modern browsers, including Firefox, feature a built-in 'Save to PDF' option within their standard Print menu. You can also use online conversion tools or dedicated desktop software like WPS Office to manage PDF creations.
