Is Xdebug Helper by JetBrains safe?

Clean risk

Xdebug Helper by JetBrains reads and writes Xdebug control cookies when you use its popup or shortcuts.

It runs on HTTP and HTTPS pages to check XDEBUG_SESSION, XDEBUG_PROFILE, and XDEBUG_TRACE cookies and update the toolbar state. When you choose a debug, profile, or trace mode, it deletes existing Xdebug cookies for that site and writes the selected trigger cookie; the checked source does not send those cookie values to a remote data endpoint.
