this has just saved me from losing over 300 tabs right now

Amazing for my 1000 tabs

This extension is awesome for keeping my browser fast and my laptop battery lasting longer. It automatically puts inactive tabs to sleep, freeing up memory and reducing CPU use without closing anything. When I switch back, the tab just reloads right where I left off. It’s super lightweight, easy to use, and works quietly in the background. Perfect for people who keep lots of tabs open but don’t want their computer to slow down. Simple, effective, and really useful.

great extension. works all right with Sideberry

great ext. save my battery and ram.

Been a Firefox user since it was an alpha release. I've never written a review for any extension until now. This extension made Firefox on Ubuntu usable for me again. I typically have several tabs opened at all time. After 12 or so, Firefox would become nearly unusable, particularly if any videos began playing in those tabs. Auto Tab Discard has made it to where I can have several dozen tabs open and everything runs fine. To the developer, thank you so much for this.

One thing I will point out is that the name is a bit misleading - No tabs appear to be discarded, thrown away, or deleted. They are just put in a suspended state and removed from active memory. At one time, I thought Firefox had a feature like this built in however, if that still exists, it no longer works very well. Auto Tab Discard is an absolute must for me now.

I think the description says it all, but I'll add that the benefits of this addon are immense, and it is amazing to me that it isn't built into the browser. This addon turned my old laptop from unusable to nice to browse on. In addition, as a heavy tabber with hundreds of tabs open, it allows me to run more memory-intensive software on my desktop without closing my browser.

It appears that the AI-powered tab grouping of Firefox keeps this extension from being effective.
You need to turn off 'Use AI to suggest tabs and a name for tab groups' in Settings > General.

The extension discards tabs more than Tab Unloading, a function of Firefox and is more flexible.
I still needs it.

Edit: Options work perfectly now, it was problem on my end.

Useful for my potatoe, but the options do not take effect for me for some reason which would be super helpful otherwise. Thank you. Shall revise the review when I can get that working.

Good, but firefox now has built-in tab discard/unload feature, so in fact you don't need this anymore.
