  • Cross-Browser Support
    OneTab is available on multiple browsers including Chrome and Firefox, making it versatile for users on different platforms.

Possible disadvantages

  • Loss of Tab Groups
    When converting tabs to a list, OneTab does not maintain any organizational structure such as tab groups, which can be a downside for some users.
  • Manual Management
    Restoring a large number of tabs can be cumbersome as users need to manually restore them, either individually or all at once.
  • No Automatic Syncing
    OneTab does not automatically sync your tab lists across different devices, limiting its usefulness for users who frequently switch devices.
  • No Search Function
    The extension lacks a search functionality within the tab list, making it harder to find specific tabs if you have a large number saved.
  • No Real-time Updates
    The tab list does not update in real-time, meaning you have to re-consolidate tabs every time you open new ones.
