Environmental friendly addon

Love it, one of my must have add-ons.

Not actually that useful. Storing Tabs in RAM may be faster on your Machine.

It depends on your bottleneck, do you have 4GB of RAM, use that Addon.

Do you have a slow Wifi card and processor, dont use it, as sites reload more often.

Really useful extension, nothing to really complain about.
Simple, Light, Effective! I use it all the time

halved FF memory usage.

C'est dommage mais le module plante. De temps en temps, au lieu de "réactiver" un onglet mis en veille auparavant, il le supprime complètement et firefox affiche une page vide.
Il est alors impossible de retrouver l'onglet et de savoir ce qu'il y avait à la place de cette page vide.

I suspect this extension is what's been slowing down Firefox for me and using a lot of my PC's memory to the point of severe lag - it's my only recent add-on and disabling it seems to have helped so far (fingers crossed). Good idea but the slow-down is very significant after a while for me at least.

Good extension, but needs better defaults. E.g. "Do not discard a tab when it is pinned" should be ON by default.

Saw a noticeable drop in the amount of memory my PC was using by about 20% after installing this add-on.

Usually pretty good, but for the past several months now I've been having an issue where sometimes, if I click on a tab that was discarded to open it, instead of loading the actual page it was on it instead just becomes an about:blank page. It doesn't happen too often, but often enough to be annoying and make me have to be more cautious than I'd like to have to be.
