PDFGuard

PDFGuard is a browser extension designed to enhance privacy and security by preventing unauthorized downloading of PDF files from web pages.

Unlike traditional ad blockers or content filters, PDFGuard specifically targets PDF downloads, ensuring users have control over their digital assets and sensitive documents.

The extension provides users with customizable controls to block PDF downloads from websites or selectively allow downloads from trusted sources. Users can easily toggle the feature on or off, allowing them to switch between browsing modes based on their privacy preferences.

Moreover, PDFGuard offers additional features such as notification alerts for attempted PDF downloads and automatic detection of potential security risks associated with downloading PDF files. By analyzing file metadata and origin information, the extension can provide warnings and recommendations to users, helping them make informed decisions about downloading PDF content.

Instructions for Using the Utility:

  1. Install the PDFGuard browser extension from the Mozilla Add-ons website.
  2. Once installed, the PDFGuard icon will appear in the browser toolbar.
  3. To enable PDF download blocking, click on the PDFGuard icon and toggle the blocking feature to "on."
  4. PDFGuard will now prevent PDF files from being downloaded from web pages. If a website attempts to initiate a PDF download, PDFGuard will block the download and provide a notification alert.
  5. Users can customize PDF download settings by accessing the extension's options menu. Here, users can whitelist trusted websites or adjust blocking preferences based on their privacy and security requirements.
  6. To disable PDF download blocking, simply click on the PDFGuard icon again and toggle the blocking feature to "off." This will allow PDF downloads to proceed as usual.
  7. PDFGuard also offers additional features such as notification alerts for attempted PDF downloads and automatic detection of potential security risks associated with downloading PDF files. Users can configure these settings in the extension's options menu to suit their preferences and requirements.

Extension safety

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

PDFGuard requires a few sensitive permissions. Exercise caution before installing.
