Vlad Sleeping the tabs is not the same as closing them.
I would like them to vanish from the tab bar, thus preventing clutter. Either the session has expired or it's a word look up.
As I have it now in power saving mode, the tabs are still there, only with a crescent moon. I would like to tell Orion to close the tabs automatically
Edit: i have looked for analog Firefox extensions but none seems to have so much power over the browser behaviour. That’s why my only hope is to see this functionality implemented in an independent browser. The closed tabs would still be in the search history but I would come to a pristine Orion every few minutes so I can automatically open a number of tabs with different multilingual dictionaries (or torrent trackers) through Alfred app without the remorse of risking to clutter the tab bar excessively.
Thank you very much!
