About This Extension

Enhance your tab management with customizable keyboard shortcuts. <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/3207e8dab7633b8b1b62c5b817bb05597c2c81e0e7b0fa39e9fc59d8f7e7d202/https%3A//github.com/wilmtang/firefox-open-tab-on-the-right" rel="nofollow">https://github.com/wilmtang/firefox-open-tab-on-the-right</a> • Open Tab on the Right: Create a new tab immediately to the right of your active tab, rather than at the far end of the tab strip. • Move Tabs Left/Right: Effortlessly shift your current tab—or a block of multiple highlighted tabs—left or right. • Smart Handling: - New tabs intelligently inherit the properties of the active tab (e.g., pinned status or tab group). - Tab wrapping is supported: moving a tab past the end wraps it to the beginning. Pinned and unpinned tabs wrap within their respective boundaries. - Highlighted non-adjacent tabs are smartly consolidated when moving, mirroring Firefox's native drag behavior. • Customizable Shortcuts: Configure your preferred key bindings directly in the extension's options page. This extension does not collect or store any of your browsing data.
