If you want the lowest possible memory footprint, choose this extension. Brings FF with hundreds of open tabs down to under 1GB with effective tab discarding. Not many bells and whistles though, maybe could use an extra feature or two.

Working, it reduced my usage: 50 tabs 2,225MB memory and was reduced to 1,262MB

Great little add-on. Would like to see it dim the icon of suspended tabs but apart from that it is perfect.

works great saves memory

It works as promissed.

Works perfectly, It's light weight and out of the way. I haven't had any issues with the reliability of this extension so far, unlike some other Tab Suspender plugins.

very good and useful
