What our analysis found

Open in PDF Reader, used by 90,000 people, showed no malicious code in Extension Auditor's review. It comes from a trusted publisher and was last updated in November 2025.

Analyst notes

The extension's use of nativeMessaging and downloads permissions is necessary for its stated core functionality of opening PDF files in external applications. The content script runs early to intercept clicks, but only adds an event listener. The only external network call is to [domain withheld] to fetch the native client installer, which is essential and expected. No data exfiltration, tracking, or malicious code patterns are present. The code is transparent and aligns with the description.

About this extension

Send PDF links directly to your favorite PDF viewer like Adobe Acrobat Reader

Read the publisher’s full description

The "Open in PDF viewer" extension opens PDF files directly in your favorite external PDF viewer application. To use the extension, right-click on a PDF link and select the "Open in PDF viewer" item. The extension downloads the PDF file in your default downloads directory and then executes the external command to open the downloaded file with the default PDF viewer (e.g. Adobe Acrobat Reader or FoxIt PDF reader). Note that to execute an OS-level command, you need to install a native client. Native client installation guide appears on the first usage. Features: 1. Open PDF files from right-click context menu 2. Transfer already opened PDF files to the external PDF viewer by pressing the browser's action button 3. Detect PDF links and open them with left-click 4. Open the external PDF viewer with a user-defined delay 5. Supports most common PDF viewers Change Logs: 0.1.1: It is now possible to define left-click open in default PDF reader from the options page. If this mode is enabled, the extension blocks the default action when a link with the PDF mime type is the target. 0.1.2: It is possible to ask the extension to send the PDF URL to the external executable. Make sure your PDF Reader can open remote URLs before enabling this option 0.1.9: You can now run the external executable with a delay. This helps your antivirus application to validate the PDF file before this extension opens it with the external PDF viewer.
