Great! Saves a lot of computer's memory. As well as helps you decide to just close the tab that has been discarded for a long time :-)

Simple, easy to use, easy to add exceptions to the discard system, or whitelist, all of that. Easy recommendation from me.

Does what it says it does and does it really good.

It would be great if it wouldn't release the tab as soon as I click it. Especially since a lot of times, closing another tab results in focusing the discarded tab.

Also, as of Firefox 78.0.2 (64-bit), due to some bug in browser, this extension is actually useless.

I'd like to rate this add-on more highly but the first option worries me greatly: '..also >trash< all tabs not active in the last 24 hours'.
Can this be serious? 'Trash' to me, American though it is, means wreck, destroy, obliterate, smash, demolish, vandalise, eliminate, break apart, disassemble with prejudice, make useless for evermore, effectively kill...
Would I want this done to tabs I've had sitting in my browser for more than 24 hours? For any number of hours? That seems absurd.
I'd like to test it, but why would I want a terminal sentence passed on any of my tabs?
Maybe it's just a poor choice of language by the author; very poor, careless.

Great in almost all ways but I would like the creator to add a feature that allows specific pages to never be discarded while other pages of the site is still discarded. (Example: example.com/example isn't discarded but example.com or example.com/example2 is)

Great extension - the "discard after x time" and hotkey options are amazing, and the dev is open to suggesstions!

This is a great extension - I finally had to find a similar extension to BarTab that I used to use before the webextension thingy when my laptop with 20GiB finally used up all the RAM, most of the swap space and slowed my system to crawl until I could free some of it... After installing this the memory use has dropped to a fraction of what it used to be. I started with the default settings, then after most my tabs were discarded I set the time before tabs get auto-discarded to much higher.

One request I have - if possible, could you make this extension to work with TST (Tree Style Tab) extension, so that if it detects TST it will show discarded tabs like it does on regular tab bar (which I've hidden because it's kinda redundant with TST)? That would be most awesome! Also you could add TST-specific features, such as "discard this tab tree", etc.
I would definitely add a star to my review for that! =)

Greatly improves/decreases memory usuage
