Latest Stylus 1.5.37 not handling userstyle for addons.mozilla.org

[ghost]

I've just updated Stylus from 1.5.35 to 1.5.37
I'm encountering an issue with a userstyle developed for addons.mozilla.org:
The style is displayed in Stylus' Manager
The style is not activated on addons.mozilla.org
When on an addons.mozilla.org page Stylus' popup

1. states No styles installed for this site
2. does not include Write style for:

This issue is new with Stylus 1.5.37, never occurred before.

[RE EDIT ]Same problem for me with Waterfox Classic (But after reinstall the previous version of Stylus i see that was the same popup...):
I see my userstyle for Mozilla in the popup, but it grayed and a message notify:
"Only v.59 can style Mozilla pages"

But i confirm the problem for Quantum.
With Quantum before update:

After Update:

The Stylus popup don't show any userstyles when i am on Mozilla pages.
But they work on them...
And in the Stylus Gestion page, they are present.

Seems there is a problem too with Quantum.....

This is already fixed in the source code.
