Does this stop you from using Cursor

No - Cursor works, but with this issue

Hey, quick note: Cursor uses the Open VSX registry, not the official VS Code Marketplace (because of Microsoft’s licensing limits).

But there’s a workaround. You can download the VSIX directly via the API:

1. Open this link and it’ll download the VSIX file:

https://marketplace.visualstudio.com/_apis/public/gallery/publishers/Triggerdotdev/vsextensions/trigger-dark/latest/vspackage

2. CMD+Shift+X > three dots > Install from VSIX

3. Pick the file you downloaded

For any other extension, use this format:

https://marketplace.visualstudio.com/_apis/public/gallery/publishers/{publisher}/vsextensions/{extension-name}/latest/vspackage

About the “Failed to fetch” error when you click Browse marketplace, that’s a known UI bug in the theme search. The team is working on a fix.

That worked, thank you Dean! Bastards, that was a dick move.
Might be a good workaround for migration from VSCode → Cursor to automatically download and use it with VSIX (or link that workaround in the popup message).
