Excellent - simple extension that makes opening links from teams faster by a good few seconds! (What a terrible "feature" from microsoft). Thanks for keeping it up to date as new link patterns come out!
by Fi*****, 2026-06-03
you are a hero–these "safelinks" actually make no link safer–just slower, more obscure, and–by absolutely no coincidence / is actually the raison d'etre–microsoft and its corporate enterprise owners get a sweet preview into every link you visit, click, copy, share, send, and preview. plus! a bonus 1-2s delay! great work, love that you made this so i didn't have to. cheers man

Is Disable Microsoft Safe Links 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.

Disable Microsoft Safe Links requires a lot of sensitive permissions. Exercise caution before installing.

Risk impact analysis details
  • Critical Request access to the following domains: office.net, outlook.com, office.com, office365.us, static.microsoft
  • High ****** *** ********* ** ******* *** ******* ******* ** ****** *** *** ******** ******
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.

Disable Microsoft Safe Links is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
