Mozilla Firefox recently received a long-anticipated feature: vertical tabs. It arrived in March 2025 as part of the Firefox 136 update. Now, Mozilla is introducing another welcome improvement to tab management in its browser, making it easier for users to pin and unpin tabs in Firefox.
With the latest Firefox Nightly update, Mozilla implemented a new way to pin or unpin tabs: you can simply drag the current page to another pinned tab to pin or drag it out to unpin it. As simple as that. The new logic works with both vertical and horizontal tab views, and it eliminates the need to use context menus. The only prerequisite is that you need to have at least one pinned tab for the dragging to work. Otherwise, you will simply move the tab across the strip.
You can now drag a tab to your pinned tabs tray to pin it, or drag it out to unpin it. https://t.co/ijlMEyNw0n pic.twitter.com/wggwFnRObi

It is nice to see Firefox implementing this small convenience for customers. However, some argue that there is still room for improvement. Dragging tabs is cool, but a dedicated shortcut could be an even better and quicker way to pin or unpin your tabs. That said, other mainstream browsers lack this feature as well.
The improved tab pinning is now available in Firefox Nightly, the least stable update channel. Mozilla uses it to test early changes and big platform changes, which could be buggy, unstable, or feature-breaking. Therefore, it is probably not a very good idea to use Nightly builds as your main browser. Still, you can run Firefox Nightly side-by-side with other channels for testing purposes.
