Disable the Acrobat PDFMaker Extension in IE11
Disabling the Adobe add-on prevents conflicts that cause Internet Explorer to freeze during PDF downloads.
The Acrobat PDFMaker extension in Internet Explorer 11 can occasionally conflict with Windows updates, especially when downloading files from a Trusted Security Zone. Temporarily disabling this extension is the most effective way to identify and resolve the freeze.
Launch Internet Explorer 11, click on the Gear icon (Tools) in the upper-right corner, and select 'Manage add-ons'.
Under 'Add-on Types', select 'Toolbars and Extensions'. In the right pane, find 'Adobe Acrobat PDFMaker' or similar Adobe extensions.
Select the extension and click the 'Disable' button at the bottom right. Restart Internet Explorer and try downloading a PDF again.
Modify Protected View Settings in Adobe Acrobat
Adjusting security settings in Adobe can stop the software from freezing the browser when opening Trusted Zone documents.
Resolve Acrobat and Reader Dual-Installation Conflicts
Removing redundant Adobe software ensures that the browser uses a single, conflict-free plugin to handle PDFs.
Open PDFs Seamlessly with WPS Office
Avoid browser crashes and plugin conflicts by using the built-in PDF reader in WPS Office. It provides a lightweight, secure, and fast way to open, view, and edit your PDF files without relying on outdated Internet Explorer plugins.
- 1. Download and Install WPS Office: Visit the official WPS Office website to download and install the free suite on your Windows PC.
- 2. Set WPS as the Default PDF Viewer: Right-click any PDF file, select 'Open with' > 'Choose another app', pick WPS Office, and check 'Always use this app to open .pdf files'.
- 3. Open Your PDF Safely: Double-click your downloaded PDF file to open it instantly in WPS Office, bypassing any Internet Explorer security zone conflicts.
Frequently Asked Questions
Why does Internet Explorer 11 freeze only on trusted sites?
Internet Explorer applies different security protocols depending on the zone. A recent Windows hotfix may have altered how the Trusted Security Zone interacts with the Adobe PDFMaker add-on, causing a deadlock or freeze when the browser hands the file over to the plugin.
Can I still view PDFs online without the PDFMaker extension?
Yes. If you disable the Adobe PDFMaker extension, Internet Explorer will typically download the PDF directly to your local drive instead of trying to render it in the browser window. You can then open the file safely using a standalone desktop PDF reader.
Does having Acrobat and Reader installed together cause problems?
Yes, having both Adobe Acrobat (the premium editor) and Adobe Reader (the free viewer) installed simultaneously can cause browser plugin conflicts. The system may struggle to determine which application should handle the web request, leading to browser crashes.
How do I update my Windows and Adobe software to prevent this?
For Windows, go to Settings > Update & Security > Windows Update and click 'Check for updates'. For Adobe, open the application, click 'Help' in the top menu, and select 'Check for Updates' to install the latest patches.
