Rearrange Tabs by Mohsin

Rearrange Tabs is a simple productivity extension that reorganizes browser tabs into an interleaved order with one click.

Example:

Original order: 1, 2, 3, 4, 5, 6
Rearranged order: 1, 4, 2, 5, 3, 6

This is useful when opening two related sets of tabs and wanting to alternate between them for easier comparison or workflow.

The extension works entirely within Firefox, does not require an account, does not connect to external services, and does not collect or transmit any user data.
