This addon is awesome for working on problematic SAML configs.

this works now! but not in private browsing mode which is where I do most of my saml testing!

Thank you so much for the update!
After update 2.0.1 pop-up window works fine in Firefox Quantum now.

Freakin lifesaver. So glad this works after the new version of firefox broke all my old extensions. I need this for my job.

It doesn't work. Dialog box is a single blank line - can't see the SAML token at all. Don't bother installing this - author can't be bothered fixing it either.

Tried with multiple SAML service providers and it never captures a message. I was hoping for an experience similar to the now-"legacy" SAML Tracer add-on (https://github.com/UNINETT/SAML-tracer/ ), but this one doesn't seem to capture any of the SAML messages via Google SAML apps, Shibboleth, etc.

I couldn't get the extension to do anything on Firefox 57. I was using containers. I have yet to try with containers.
