Lightweight, close to no memory and CPU usage. It's compatible with Zen as well.

Actually makes any firefox based browser usable, clear, simple to control/configure.

Automatically suspends tabs that stay inactive for a certain time (5 sec to an hour), without losing the context (e.g., if you are in the middle of watching a Youtube, it doesn't forget where you are).

When you click on a tab it re-activates it, and goes from where it was. You can also whitelist tabs that you want to stay always active, like gmail, or whatever else you may have possibly pinned.

Some users said it does nothing, or that it doesn't work, but it's user error, or maybe older version had such issues. For me, it's perfect, and does exactly what it claims and I needed.

Does what it's supposed to do. Please consider adding 3 min suspender! Thank you : )

YES! Finally something that adequately curtails the poorly implemented tab management within FF's backend. Before installing this, I'd get these frequent CPU/memory spikes and my MBA fans would ramp into overdrive—all because I dared to have (gasp) a dozen or so tabs open across (BIGGER GASP) two different windows, even if there are no YouTube videos playing, even if a majority of the tabs don't seem like they should be resource-intensive.

For someone who doesn't have the ability to augment their current RAM setup, this app is a total lifesaver! All its core settings (timer, whitelist, ignore functions) work like charms. Now I can use my browser without needlessly bogging my entire system down. What a concept!

Thank you, Pradeep! If there's any way to show you some direct support (Paypal, Venmo, etc), reach out!

Great tool for people like me who are living on low RAM. please add a 3 minutes window/ custom window for "suspend after dropdown"

Been using for over a year. Works automatically in the background and I've been able to have close to a hundred brower tabs which are suspended. It allows to modify the time before suspending, from 5 seconds to 1 hour. Highly recommend.

this one actually works

Only one extension that correctly works for me. I'm glad to see that it has a options for settings

Serves its purpose, similar to Edge's Sleeping tabs
