For me, doesn't do what it says it does. Tabs are not suspended, they are completely discarded. There are no distinguishing features between active and discarded tabs (icon is unchanged, there is no dot). Switching to the tab, it starts blank and has to completely reload itself from the Internet. If I were trying to continue reading on an airplane, lets say, I would be out of luck. Maybe that is what it is supposed to do but that is not the impression I got from the description.

Significantly more features than other tab suspender extensions. Allows tabs to be "whitelisted" on a per-session basis, and provides a lot of config options for enabling/disabling suspension (e.g. only suspend when more than 6 tabs inactive)

Greatly speeds up my browser with the huge amount of tabs I tend to keep open in my sessions. Big thank you!

Perfect to reduce the RAM usage if you have a lot of tabs pined.

Absolute lifesaver!

Simple, yet powerful, working perfectly and life(memory)-saving! Thanks a lot!

My tabs are being randomly discard even after setting to zero second.

Can anyone tell my why?

Great addon.
My laptop has 8GB of RAM and it was freezing because I keep many tabs open.
This addon solved the issue.
Thank you very much :)

Simple and Works like a Charm

my go to suspender atm, the Best at 2019-09-05

does not suspend currently active tabs that match suspend rules :(
however does have a nice whitelist and timeout rules

Good extension! It does what it says, and the options are pretty flexible.

My only complaints are: a) I wish it cached page data when discarding, b) I wish it wouldn't resume a page just because I've ctrl+tabbed past it; I'd love an option to make it resume on click as in The Great Suspender, and c) I wish it could do more about the FF memory usage, though that last one is as much on Mozilla as the author.
