devtools_capabilities - Browspark

Report the browser version, connection mode, and supported operations. Chromium CDP domains are probed live and cached; Firefox reports the WebDriver BiDi adapter coverage and explicit exceptions. A partial domain does not support every Chrome command.

The tool names stay the same across browsers. See browser selection and Firefox and Zen exceptions before choosing an operation.

Parameters

integer

Target tab id from browser_tabs, which lists tabs across all windows. Defaults to the agent’s most recently opened usable tab, or the only usable tab. Otherwise select a listed tabId.

boolean

Example

{
  "tabId": 1234
}
