This is an exemplary add-on! It does what it says: it cycles out old tabs to reduce system load and improve speed. It is thoroughly configurable. I can't recommend it enough!

THIS EXTENSION IS AAAAWWWWWESOME!!!!
I had about 30 tabs open and using about 75% of memory, but AFTER installing and activating the extension it WENT DOWN TO ONLY 48% memory use! I Love that I can deactivate all tabs except the one I'm using at the time.
THIS IS AN INCREDIBLE AND VERY USEFUL TOOL!!! Thanks Richard my brother!

Great extension, just one tiny little edit should be considered, would it be possible to discard the tab that's currently in focus? I would like to leave an empty tab opened then if the tab in focus is idle it discards it and goes to that empty tab (this already happens if I manually press the discard button on the focused tab) but it would be a lot better if it were done automatically after the time has passed.

Thanks, once again a great extension.

Shocking reduction of memory usage for somebody who loves to keep ~20 tab opened !

Great addon, very much needed for tab junkies like myself. Could it please be updated so that Firefox Nightly (77+) can take advantage of the tab-memory-size trigger? This would be better than merely using timers to decide whether to unload tabs. TIA

Excellent add-on. Does exactly what is says and very very well.
It seriously can cut down on memory usage in seconds. Really helpful!
Props to the developer!

This should be stock.
