Comp/Con failing to link with Itch.io

[WitchVulpes]

So, exactly as the title says, Comp/Con keeps failing to link to my Itch.io account, and returning an error (500).
How can I fix this? Or is this a Firefox issue?

sorry about the late reply, does it work on another browser or in incognito? It's a pretty straightforward oauth but there's a chance something like an extension or browser settings may be disrupting the callback

This fixed it. It was a Firefox Nightly issue. Microsoft Edge had no problem.
