Hello !

I have read the excellent thread from [lvillacin](https://community.auth0.com/u/lvillacin) about [using Auth0 in a chrome extension popup](https://community.auth0.com/t/ultimate-guide-to-auth0-in-a-chrome-extension-popup/61362/8). This is working very well and I’m glad to be able to silently login my users in the extension.

However, when I tried to make it work for Firefox, I encounter a pretty concerning issue:

While it is advised to use `chrome-extension:extensionid` as redirect\_uri, this can’t be done because [firefox extension uuid are non deterministic](https://discourse.mozilla.org/t/constant-or-well-known-mox-extension-uuid-for-webextension/9701/7) and change at every install, thus cannot be whitelisted in the Auth0 dashboard.

Do you see any solution for this ?

Best,

Maxime

I manage to create a working solution, I described it on StackOverflow: [Auth0 in Firefox Add on - Stack Overflow](https://stackoverflow.com/a/72129178/5324537)

Hope this helps
