How to Enable or Disable Sleeping Tabs in Microsoft Edge Chromium  

just one more question , after enabling sleeping tabs , none of tabs turned gray after 5 min (i put 5 min inactivity) and there is no "this tab is sleeping" tooltip when i hover over tabs

Not sure why they wouldn't be put to sleep after 5 min of inactivity. With this technology, it is possible that some sites may not work as expected after they go to sleep. Microsoft has built heuristics to detect these scenarios and prevent those tabs from sleeping to keep you in your flow.

Do you have any of them added to the Never put these sites to sleep list?

thanks , my white list is empty , I used "the great suspender" before but then edge and chrome removed it because of security reasons and now I can't find a good alternative to suspend tabs, just saw "marvellous suspender" very similar to TGS

Thanks for the tutorial. :)

For a better control of discarded tabs you can open edge://discards/

How do u force a tab to go to sleep?
