---TO THE DEVELOPER:
CHECK THE 1 STAR REVIEWS, AS IT SEEMS THAT THIS ADDON DOES NOT WORK AS IT SHOULD?

Thanks, thanks and thank, i was going to do it by myself because the rest of them are over complicated or under functional. I would have ended doing it more or less the same.

I miss a couple of things.

1/ A button or something to discard all new tabs opened since X time ago until now.

2/The opposite, something to start discarding all new tabs opened since right now until X time in the future, or until idle user detected or explicitly deactivated or similar.

3/ The auto trash is great but i strongly miss an option to send the tabs to somewhere before trashing them. A bookmark folder or wherever.

4/ Something to see what is happening under the hoods. Nothing special. Basically how much tabs are in the deactivation queue to see the speed of the thing.

5/ A panic mode. I mean, deactivating or even blocking you opening new tabs when certain thresholds are meet. This feature would be a killer. Cause you know, there is a no return point when the system freeze and it is too late to do anything.

Well, thanks again.

EDIT:

I guess another feature, a bit strange, but would be a killer, at least for me.

Imagine you are in duckduckgo searching for some python stuff and you open 30 related tabs. I would like to open all of them deactivated but the very first 5, and after reading and closing one of these opened ones, begin loading automatically one of the deactivated ones so i don't have to wait for it when reached.

A kind of "OPEN DEACTIVATED, BUT (X), AND TRY KEEP ACTIVE (Y) LEFT AND/OR RIGHT

Perhaps with the option of autoactivate a tab in the same domain?

great extension , i am using this extension over 2 years and my main reason switching from chrome to firefox

Great addon to save your computer resources. Low on RAM or want to cut back your CPU usage, try this addon. Will suspend tabs in the background, freeing up RAM and using less CPU resources.

4/5 stars because there is one small bug that if you click on a discarded tab right after it's discarded, the page will fail to load. Fixed by a quick refresh.

It has to be set every time you start Firefox, a waste of time and NOT WORKS

Doesn't respect the time set before inactive tabs are to be discarded and just discards tabs after the default 10 minutes.
