While this does work, unfortunately the option to disable tab discarding while using an AC power source doesn't work. (the option is greyed out on 2 machines)

Does what it says + more. Teaches you how the internet works under it's facade as you use it. Stays out of the way and saves big on RAM!

Buen complemento del navegador

你测

Very good, heaps of customisation as well as the excellent default settings - Top work :-)

amazing add-on with a top-tier user experience!

本来某个页面打开一会后会占用2.5G, 使用这个插件后变成了9G...

This is exactly what I've been wanting! I've been fighting the Firefox memory hog for much too long, needing to close and restart Firefox multiple times per day. The built-in tab unload options didn't seem to do anything, or maybe not enough. It took me just one day using Auto Tab Discard to get in the habit of whenever I'm finished with a tab but don't want to close it, I right click on the tab, click Auto Tab Discard, and Discard Tab. That keeps my memory usage at bay. I also keep an about:unloads tab open and periodically check to see if I should manually unload a tab that I missed. Unfortunately, you can only unload from the top down, not selectively. But in combination with Auto Tab Discard, I now have no reason to abandon Firefox, which I was thinking of doing. Firefox REALLY needs to have a native way to control memory usage that actually works! (Note: I also use the Simple Tab Groups extension and keep dozens of tabs available for easy access, so Auto Tab Discard works great with Simple Tab Groups.)

I used to love this tab add on but now all these little windows open up on the bottom of Firefox. Why? I do not like that. I used to be able to click on the Firefox icon to open it back up on the bottom of the screen but cannot do that now.

This is exactly what I was looking for and works perfectly for my needs.

Great add-on to suspend tabs and put them to sleep to save memory, manually and automatically. The only issue is I wish there was an option to not auto load the tabs when I view them. There should be a blank page with the title of the tab written on it, and you only load and view the page when you click on the blank page

There could be a setting to delay the release of left and right tabs discard, for when you are just checking the active tab back and forth, and for when you really know you want the active tab, but loading the left and/or right tab(s) makes it take longer.
