Nice and simple!

Solid and privacy-conscious! I just tried this for merging two PDFs together and it worked without issue. Many other extensions aggressively ask for access-permissions in Firefox, e.g. "read and manipulate your download history." This extension doesn't require that, because the author clearly knows that's not needed <3

Is PDF Tools for Firefox 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 Tools for Firefox does not require any sensitive permissions.

Risk impact analysis details

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 Tools for Firefox is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
