Traditionally, the only problem with sleeping tabs is not knowing which tabs have been put to sleep and which ones haven’t.

Although this isn’t the end of the world, it’s still nice to be able to quickly and easily tell what’s going on on your system, especially if you are someone who has a million tabs open at the same time. If you haven’t enabled Sleeping Tabs in Edge yet, make sure you check out the following guide.
