Reopen Leftmost Tab and Close Others Autor: LUCELIO GUEDES

The "Reopen Leftmost Tab and Close Others" browser extension works as follows: when clicked, it first identifies the leftmost unfixed tab in your current window. Then, it opens a new tab with the same address (URL) as that leftmost tab. Finally, the extension closes all other unfixed tabs that were open in the window, keeping only the newly created tab with the content of the first unfixed tab.
