Of all the extensions, this was the best one I tested. I was looking for one that would unload all my tabs in the background and this one delivers what it promises.

This was the lifesaver for my laptop with only 2GB ram. I switched to "Auto Tab Discard" because it has an "... only if number of inactive tabs exceeds [ ]" option. Tab Unlader has the better ui and the better icon though, so I hope competion will bring further improvements. More memory-awareness would be nice, i.e. discard tabs if FF memory consumption exceeds [ ].

Great addon. Sadly the developer never answers the feedback sent to the mail provided.

Useful addon to reduce memory usage. Also I can avoid some web sites keeping watching my access.
One inconvenience: Favicons of unloaded tabs are lost in restarted Firefox.

I really like it, it's very useful. But the tab context menu don't work with Tree Style Tab. Please fix that. Thanks

Please auto white-listed web page with changed form.

Work on FF58 :)

it's ok, but can we get "keep tab loaded" or "keep this site loaded" option?
