Starting with version 88, Microsoft Edge automatically enables the Sleep Tabs feature for all users. Wondering why some of your tabs are faded in the Edge toolbar? Here’s how the Sleep Tabs feature works (and how to turn it off).
Why do some tabs fade with the Sleep Tabs feature?
Sleeping Tabs is Microsoft Edge̵
Let’s say you haven’t touched a tab with lots of resources (like a Google Sheets spreadsheet) for a few hours. Chances are, you won’t need it any time soon. The extension would basically close the tab (stop all resources assigned to it) and create a placeholder so you can reload the web page when you came back.
This little trick can help you save quite a bit of RAM and improve performance on Windows and Mac machines with less than 8 GB RAM.
Microsoft Edge does this in a different (and arguably better) way. Rather than suspend the tab altogether, Edge will only pause it as it is (still taking up some of the resources).
So if you click on a faded tab, the website will be in the exact same state it was when you left it. You won’t even notice that the tab was technically in sleep mode and wasn’t taking up too many resources.
According to Microsoft, “Using sleep tabs on Microsoft Edge typically reduces memory usage by an average of 32%. It also extends battery life as a sleep tab uses an average of 37% less CPU than a non-sleeping tab.”
By default, Edge puts a tab to sleep after two hours of inactivity, but you can adjust the time to your liking (between 5 minutes and 12 hours).

Disable the Sleep Tabs feature in Microsoft Edge
As we mentioned above, the Sleep Tabs feature in Microsoft Edge is non-destructive. You can continue to use Edge as you normally would, and you won’t even notice it’s turned on. Since Edge does not suspend tabs, you don’t have to wait for the page to reload or worry about data loss.
But if you don’t like this feature, you can turn it off with just a few clicks. To get started, open the Microsoft Edge browser on your Windows 10 PC or Mac and click on the three-dot menu icon in the top right corner of the toolbar.
Select the option “Settings” here.
Now select the “System” tab in the sidebar. Then turn off ‘Save sources with sleep tabs’.
The Sleep Tabs feature is now disabled and you will no longer see faded tabs.
