Pronoun Trouble

A tab suspender. It takes any internet tabs that you aren't using right now and puts them to "sleep" so they don't slow your computer way way down. I had a nice one a while back where I could mark tabs as "do not suspend" and they would never be suspended, but it got tossed out in a Firefox update and I had to install a new one that won't let me do that. If you're active enough on a specific tab, it should remain unsuspended automatically, but I haven't figured out the exact formula yet. I thought I had, and then I clicked away for sixty seconds and the tab suspender suspended the tab and ate the post I was working on 😡🤬
