browser_handle_dialog
Resolve JavaScript dialogs (alert, confirm, prompt) that block browser tab execution. Accept or dismiss dialogs to unblock scripts and continue automated web interactions.
Instructions
[Disabled] Handle a JavaScript dialog (alert, confirm, prompt) that is blocking all script execution in a tab. JS dialogs (alert(), confirm(), prompt()) freeze the entire page until dismissed — no other browser tools will work while a dialog is open. Use action "accept" to confirm/dismiss alerts, "dismiss" to cancel. For prompt() dialogs, provide promptText with the text to enter before accepting. Common scenario: a tool call times out or errors because a dialog appeared — call this tool to dismiss it, then retry the original action.
