Highlights

Showing the 12 most recent highlights from 42 user-facing changes.

New

  • Let extensions sign you in silently through their web authentication flow, so Claude stays signed in across launches
  • Organize open tabs in named, colored folders that sync and move between saved and open tabs
  • Keep videos visible in native Picture in Picture when switching Mac tabs, with an option to turn automatic entry off

Improved

  • Keep one extension sidebar open in each Space and switch assistants from the toolbar
  • Move tabs and whole folders through the sidebar with clearer placement and immediate access after mobile drops

Fixed

  • Deliver messages from websites embedded in an extension’s side panel back to that extension, as Chrome does
  • Let extensions group tabs and open side panels in your window even while one of their popup windows has focus
  • Give extensions with a module background worker the same tab grouping surface as classic workers, so Claude's browser tools can anchor to a tab group
  • Improve Claude and ChatGPT browser tools, sign-in, page reading and screenshots
  • Keep website styling extensions from changing other extensions’ sidebars
  • Support extensions such as SponsorBlock that use relative background-worker paths
  • Recover synced open-tab folders after updating Crest and handle unsupported folder records on older versions
