Send a crash report

Sval sends a crash report only when you choose to. Each crash dialog has a box for sending it, and the box starts unchecked.

Sval crashed while you were watching a video, and you want its developers to have what they need to fix it.

  1. In the Sval Crash Reporter dialog, check the box that tells Sval about the crash.
  2. Optional: check Include the address of the page I was on.
  3. Select the button that restarts Sval, or the one that quits it.
  1. On the crashed tab’s page, check Send an automated crash report so we can fix issues like this.
  2. Select Restore This Tab.
  1. At the bottom of the panel, select Send Feedback.
  2. Under Sent with your feedback, check the crash snapshot.
  3. Type a message about what happened.
  4. Select Send.
  • The crash dialog remembers whether you checked its boxes, and starts that way next time.
  • The feedback form lists the crashes of the last three days. A crash already sent from its dialog shows as Sent.
  • A crash snapshot is a copy of the crashed process’s memory. It may include parts of pages you had open.
  • Crash reports go to Sval’s own server.
