Prevents online PDFs from automatically saving to your computer.

Features & Capabilities

This extension prevents PDF files from being saved to your computer when you open them. It allows you to view these files at the URL they were downloaded from.

Safety

The extension is tiny and contains no scripts at all.
The extension requires host permissions ("Access your data for all web sites") in order to modify web requests. See Implementation below.

Implementation

PDF Always In Tab works by removing the ?forcedownload=1 URL parameter.

Alternatives

If you prefer not to install the extension, you may enable browser.download.open_pdf_attachments_inline in Advanced Preferences (about:config) to modify Firefox's default behaviour. This will prevent the PDF from being saved to your computer.

However, unless you remove ?forcedownload=1, the tab will be duplicated every time it reloads.

Is PDF Always In Tab Safe?

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.

PDF Always In Tab requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

PDF Always In Tab is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
