The best one with the most options of those that I've tried. No need to keep looking. Thank you!

top top top. c'est LA solution aux problèmes de lenteur du navigateur.

Ultra top, faz o que promete com extrema fidelidade e simpatia e ainda informa quais guias foram "hibernadas", todos deveriam conhecer esta extensão, parabéns ao desenvolvedor!!!!!

I can't live without this anymore. I have it set to discard after 3 hours and trash after 12, so that within a working session I can horde all I like, and it'll clean up after me. It won't discard if the page has a form that's not empty, and I can easily mark a domain to never discard, so there's no worries about losing my work. This extension is a lifesaver.

Never thought this would be a 5-star, but its just so invaluable for tab hoarders and people researching new topics on low memory machines.

Mal funktioniert er und dann wieder nicht....früher war er top da gab es auch keine zusatztsoftware......weniger ist mehr

部份在背景打開的分頁在被休眠後將永遠丟失，無法復原

It's very useful for me, except that the discarded tags are included in the total number of tags。

Das Add-on funktioniert einwandfrei! Sehr zu weiterempfehlen!

Really saves RAM on my X230

Great! If you don't have lots of RAM memory you need it. It will free all unused the tabs from memory allowing you to open as many tabs as you want to.
