Microsoft Edge 100 was released a few days ago and is basically a security update. The Redmond company pointed out that the latest version improves browser performance with a more optimized version of Sleeping Tabs.
The feature debuted in September 2020, when Edge Canary 87 was released. It was rolled out to all Edge 89 users in March 2021. As you browse the internet and accumulate a certain number of tabs, the browser starts consuming more resources, which leads to a drop in system performance. Sleeping Tabs monitors tabs that you haven’t used for a while, i.e. inactive tabs, and automatically repeats them. This is also called tab unloading, tab dropping, or tab repeating. Edge isn’t the only browser to natively support it, it’s also a feature you can find in Google Chrome, Mozilla Firefox, Opera, and Vivaldi. Waterfox G4.1.0, which was released yesterday, added tab unloading and lets you repeat tabs manually. Brave Browser is the only one that doesn’t natively support Tab Snoozing, but this can be easily fixed using an extension like Auto Tab Discard.
I think we can agree that sleep tabs are a handy feature, and Microsoft Edge 100 makes it even better. the announcement from the company says that Edge will put 8% more tabs to sleep, to save more resources. How it works? Pages that share a browsing instance with another page will be paused. This saves Sleeping Tabs up to 85% memory and 99% CPU usage on average. Changing the Efficiency mode in the Performance pop-up panel to “Always” will repeat tabs faster.
It’s pretty impressive, and if you’re interested in crunching numbers, you’ll probably like it. Edge 100 has added a new Performance Monitor, to let users see how Sleeping Tabs helps save system resources. To access it, click on the three-dot menu and select Performance. This will open a pop-up that displays the number of sleeping tabs and a graphical indicator to show you the percentage of memory saved with sleeping tabs and remaining usage. You can pin the performance monitor to stay on top, to keep an eye on resource usage. It’s a decent way to monitor the system, although Windows Task Manager still beats it, as you can get a breakdown of resource usage by tab.
There is no option to put tabs to sleep manually, although users have asked the feature on Microsoft’s Feedback Hub. You can whitelist websites in the Optimize Performance section of the edge://settings/system page. This will prevent Edge from repeating site tabs, this can be useful for sites you use for email, instant messaging, sports websites that automatically refresh to update scores, etc. You can set tabs to repeat after a specific duration, such as 5 minutes.

Don’t like the feature? You can disable sleep tabs in Edge from the Settings page.
Edge 100 also brought new features such as the ability to preview PDF files using File Explorer and Microsoft Outlook powered by Edge’s web view, and support for viewing Digitally signed PDFs.
