Important: This only works with recent versions of Microsoft Office See below for more info

Modern browsers, such as Chrome, Firefox or the new Edge do not allow local contents to be linked from a site served over HTTP(S). This is a security feature, which though hinders some applications, like linking to local office files from a corporate intranet. This extension enables you to open Office files locally from a link.

This addon only works with recent versions of Microsoft Office, since the URL-scheme support was incomplete in earlier versions.

Versions confirmed to work:
- Microsoft 365 MSO (16.0.13530.20490) 64-bit
Versions confirmed not to work:
- Microsoft Office 2016 (16.0.5110.1000) 64-bit

Risk impact

Office Opener requires a number of risky permissions that can potentially harm your browser and steal your data. Exercise caution when installing this add-on. Review carefully before installing. We recommend that you only install Office Opener if you trust the publisher.

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, bypass your security settings, and access your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Risk likelihood

Office Opener has earned a fairly good reputation and likely can be trusted.

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 Browser Add-ons, 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, especially ones with higher risk impact and/or higher risk likelihood.
