    Thanks for reporting. Looks like a CORS problem with the open-vsx repository prevents Calva from being installed. Can you check in the Extensions pane if Calva is even there?

    I find this closed issue on Gitpod as my only clue right now: gitpod-io/gitpod#4460

    I'm also asking for help in their Discord, let's hope we can find out how to fix this!

    Let me look into this and ask internally @PEZ!

    @divs1210 Do you use any firewalls or adblocking software? Some of them remove etags and it breaks browser caching, see: gitpod-io/gitpod#4391 (comment)

    @akosyakov

    CORS issues are irrelevant, if VS Code cannot pull extension through the browser, it works around CORS on the backend.

    Actually yes, I do use uBlock Origin and ClearURLS.

    I will disable them and try again and let you folks know.

    @akosyakov ClearURLS was causing the issues.

    On disabling it, the editor loads just fine - I'm seeing code highlighting and can start a REPL.

    Awesome news! I will update the instructions/readme with this info.
