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.

This is greatest addon.
Makes Firefox usable again.
Without it Firefox eats too much memory and is sluggish.

I have also adjusted discard time to few hours to prevent unintended discharding .
I want to discard tabs only if they are not used for more than day.

With some settings adjustments (e.g. raising the discard delay to more like an hour than just a few minutes) this module works just great. Using it I managed to tame Firefox' memory consumption enough to make it a stable browser again.

I categorize this add-on as *essential*, at least for people who use more than a handful of tabs, and/or who don't like wasted RAM. **Ever since installing this, it's as though I installed another 2 GB of RAM. ** It should be built in to Firefox. I wrote angry letters to Firefox about their reckless waste of RAM, and even suggested they free up memory exactly as this add-on does. Firefox is nasty -- it will keep on using RAM till there's 98% memory in use and the whole machine grinds to a halt. I was on the verge of abandoning Firefox over this. No installation of FF is complete without this functionality.

This add-on makes my 7-year-old laptop not hang anymore. Now I can wait for the Ryzen 3000 price drop after the initial launch. Thanks bro

It's good. Works almost like The Great Suspender for Chrom(e/ium).

Amazing add-on! Lots of options to customize it to your liking as well.

Literally saved my laptop. Now I can continue hoarding tabs like I usually do without the laptop slowing down to the point where it would take forever to do anything :D
