There is also the auto-tab discard Extension. Which reportedly uses Native API better. I've seen that compared to other tab suspenders it does keep tabs sticky between sessions. However, I'm not a fan of it's auto-foreground on clicking a tab behavior. I think, The Great Suspender Extension on Chrome handles this better. https://addons.mozilla.org/en-US/firefox/addon/auto-tab-discard/ https://addons.mozilla.org/en-US/firefox/addon/auto-tab-disc...
