objections

  • objection: Will switching mean rebuilding my browser setup?
    response: The company describes migration of browsing history, logins and cookies; test the migration and password import on a noncritical profile first.
  • objection: Will my extensions work on a WebKit browser?
    response: SigmaOS says it supports popular Chromium extensions, but test each essential extension because compatibility can vary.
  • objection: Is it actively maintained and supported?
    response: Confirm current releases, account creation and support directly before relying on the browser for business-critical workflows.
