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.
