SharedWorkerBlobURLFixEnabled

Make SharedWorker blob URL behavior aligned with the specification

Supported on:

  • Chrome (Windows) since version 132

Description:

Upon https://w3c.github.io/ServiceWorker/#control-and-use-worker-client,
workers should inherit controllers for the blob URL. However, existing code
allows only DedicatedWorkers to inherit the controller, and SharedWorkers do
not inherit the controller.

Setting the policy to Enabled or leaving it unset means
Samsung Browser inherit the controller
if a blob URL is used as a SharedWorker URL.

Setting the policy to Disabled leaves the behavior not aligned with the
specification as-is.

This policy is intended to be temporary and will be removed in the future.

true = A blob URL SharedWorker inherits a controller.
false = A blob URL SharedWorker does not inherit a controller. (legacy behavior)

Supported features:

  • Applied to browser only after restart.
  • Applied at Samsung Browser profile level.
