Unfortunately, Google does not let you roll back to the old compose window, thus you do not have any option but to stick to the one you have been provided with. Fortunately, you now have a third-party option to get back the old compose window in Gmail. The solution comes in the form of browser extensions that you can install inside your preferred web browser to still enjoy the old email compose experience you loved a lot. As of this writing, the extension is only available for Google Chrome and Mozilla Firefox. So if you use one of these browsers, here’s how you can install the extension and enable the old compose window.

Bring Back the Old Compose Window using Chrome

  1. Head over to the Old Compose page on the Chrome Web Store website.

  2. Click on the “FREE” button given in the top-right corner.

  3. A pop-up should appear asking if you really want to add the selected extension to your browser. Click on the “Add” button and the extension will be added to your browser.

  4. When your browser has installed the extension, a success message will appear on your screen that looks something like the below image. You should also be able to see the extension icon in your extensions bar.

  5. Now visit the Gmail website in your browser and click on the “Compose” button. You should see the fully-sized new email window rather than the small one that used to appear in the bottom-right corner of your browser.

If you ever wish to go back to the smaller window, just uninstall the extension and it should do the job for you.
