Without this add-on, Firefox has become an unwieldy, slowly dying wind bag. It will suck in 6GB of memory in a handful of hours, with heavy browser work. That's because of the tons of scripts and media being run on your computer. Even NoScript is not a good alternative, because it's very cumbersome - even if you use it for safety. Just be sure for ATD, that you spend a few minutes in OPTIONS (Tools / Plugins / ATD - Options) because you'll be consuming A LOT of bandwidth needlessly RELOADING stuff you're in the middle of. I am currently using 1,800 seconds before discard (30 min.), instead of the default 600 (10 minutes.)

Does what it says

Auto Discard would be great too! And ofc s/discard/suspend/.

Even better than it's predecessor!!!

Para ordenadores con poca memoria ram es ideal. Tambien para aquellos que mantienen abiertas múltiples pestañas simultáneamente. Los ajustes son variados y adecuados.

Powerful! So glad to regain control of my CPU from poorly written web pages running in the background!

This is great!

I consider this to be a mandatory to use addon.
If you have lots of tabs, Firefox does not have any automatic way of preventing them from being loaded forever, eating RAM in the background, and this is where this addon helps greatly.

Great addon; useful and efficient.

To the developer:
Could you make the favicons dimmer when a tab is discarded? sometimes I forget which tabs are unloaded and end up loading them by mistake.

Is it possible to automatically discard non-active tabs when a certain amount of RAM is being used?

Thanks for the addon. It's a lifesaver.

Greatly reduce my Firefox memory usage, and prevent tabs automatically reloading when opening the browser.

Switched to this from Tab Suspender. Needed something that would work with the Tree Tab (Kroppy) session export feature. This extension does the job perfectly.

It makes FF usable again - without it FF eats a lot of CPU/Memory if you have many tabs

This does not work with F58 but if you read the description you will know this works with F59, which is currently in alpha. Use F59 if you want this.

Love it! Much smoother than the non-native extension. One thing though: can you implement sync for settings and exceptions whitelist?

Great addon. It doesn't seem to discard tabs with forms, though, even if I configure it to do so, and even if the forms have no new text input (i.e. any random page with a search box isn't unloaded).

Thank you for implementing my suggestions. The addon is great.
