Firefox browser extension that can disable the persisted queries GraphQL feature on Twitch.tv
// Note: This only works in Firefox!

// Load the extension in about:debugging
// If it doesn't seem to be working then click the Inspect button and see if there's any information in the Console tab
// One issue with old Firefox versions is that the host permission isn't automatically granted. Double check this in the Add-ons Manager.

How to limit `docker buildx build` concurrency

If your computer is running out of memory during a docker build, or if the build is CPU intensive, you might want to try building one architecture at a time.

[worker.oci]
max-parallelism = 1
