A “crash” occurs when Vivaldi encounters an unrecoverable error and shuts down unexpectedly or a tab’s contents disappear and are replaced with a “dead bird” image. Information pertaining to the crash is logged by macOS.

Locating Crash Logs

  1. Launch the “Terminal” application—open “Spotlight”, type: Terminal
  2. Copy and Paste the following text into the Terminal window and press “Enter”—triple click to select
    find ~/Library/Logs/DiagnosticReports -mtime -7 -name Vivaldi\*.crash | zip -j ~/Documents/Vivaldi\ Crash\ Logs\ $(date '+%Y%m%d-%H:%M') [email protected]
  3. Inside your “Documents” directory and you will find a dated zip file called “Vivaldi Crash Logs”

Submitting crash logs

Crash logs are not sent back to us automatically. However, you can create a bug report and let us know about your issue.

After logging a bug report you will then be sent an confirmation email. Simply reply to this with your crash log(s) as an attachment. Such logs are greatly appreciated; they provide us with information as to exactly where in the code things went wrong.

Make sure the crash happens on the latest version of Vivaldi. If you’re not on the latest version, please update the browser and test the issue again.
