Microsoft Edge build 91.0.831.1 for the Edge Insiders in the Dev Channel gets some new features and improvements. Among those, there are two new features that we want to highlight here. The first one is the ability to apply Color Themes, and the second one is the ability to sign-in and sync for the Linux users.
Back in December 2020, Microsoft Edge Canary build 89.0.731.0 received a new personalization feature, that allowed you to apply custom accent color to the browser window. During that time, as the feature was under preview, it was hidden under an experimental flag "Enable picker for color based themes".
Now, with the release of Edge Build 91.0.831.1, this feature is more widely available to Edge Insiders who are currently receiving the Dev Channel builds. We should see this feature running soon to Microsoft Edge Beta and Stable channels soon.
These themes will allow you to change the look and feel of your browser window with colors. Navigate to
