After seeing "Webpage using significant energy" all the time and moving and clicking the mouse felt like I'm in a slow-motion video, I decided to install the Great Suspender that Chrome has and I use every day at work, but, lo and behold another extension that does not exist anymore in Safari thanks to their excellent decision of killing all the existing Safari extensions made until 2018?.
After googling for a while I found myself here, so while I did not have the issue the previous user mentions, there are a couple of gotchas, especially if you are used to the Great Suspender.
- It does in fact reduce the ram and cpu used by Safari. I don't know if it reaches the claimed "60%", but, there is a noticeable difference
- It has some interesting configuration options
- Dark mode! It's useful to scroll through the tabs at night without getting temporary blindness
- Premium: I'm used to free extensions in Chrome so this got my attention. On the other hand, all free options are fine for most users plus if you do go premium, it's a one time payment and you get it for less than $1
- There's this message "Restoring tabs" that shows up every time you start Safari, it's a bit annoying if you restart often. I get it's there for a reason so I assume Safari does something that other browsers don't? After the great extension massacre I appreciate more the ones that survived it so I won't punish the rating for this.
There's room for improvement but in the end it does its job well. My mbp still overheats, but not enough to fry eggs anymore
