This is great!

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.
