Greate extension.
Suggestion - don't restore suspended tab automatically when I click on it.
This extension is really useful when working with a lot of tabs and sometimes switching between +20 tabs I accidentally restore suspended tab.

This is the lifesaver for my laptop with only 2GB ram. Now I can never need to micro-manage open tabs again because they get unloaded automatically. Firefox memory consumption is way below Chrome now. Thanks to the dev!

Fantastic addon for people like me who tend to have a massive amount of tabs open to remember them, or for reading later but that aren't "worth" bookmarking, and/or for reference purposes, combined with tree style tabs, this is magic.

Works perfectly, even with Tree Style Tabs :)

Feels really thought through and polished up

Interesting to see my CPU usage lowered

I like it it really saves memory

This add-on definitely allowed my PC to run cooler and also made Firefox more efficient on CPU usage.

Wow! This add-on truly works like a charm. I love how this add-on allows me to hibernate any tab of my choice. My browsing experience has improved greatly.

Saves lots of memory, integrates well with TST and can be configured in many ways. For example, it can be configured to ignore tabs that can send notifications (chats etc).
