https://github.com/faisalbhuiyan3038/the-firefox-suspender

A Firefox extension that automatically suspends inactive tabs after a specified time to save memory. Unlike Firefox's native tab discarding, and popular addons like Auto Tab Discard, this extension shows a custom suspended page that you need to click to reload - preventing accidental tab reloads when you mistakenly click on a tab.
