Right Next Browser Extension Right Next browser extension make new tab place right next to current tab. Advantages Right Next can handle these situations:

Open new tab in foreground/left click.
Open new tab in background/middle click.
Open new tab from pinned tab.
Open new tab from/to container (tabs permission required since 2.0.0).

Right Next also done with very less code which make it has good performance. Permission Required optional_permissions

tabs: please give this permission if you using container extensions (since 2.0.0).

End Support When Mozilla fixed this issue, then this extension has its mission done. Alternative If you don't open new tab by middle click, you can simply change these settings:


  browser.tabs.insertAfterCurrent: true
  browser.tabs.insertRelatedAfterCurrent: false

These extensions work well too, but can't handle all situations.

Open Tabs Next to Current - can't handle container tab.
Always Right - can't handle middle click because it simply change your browser settings which affect by the issue mention above.
