User reviews
Thank you so much Frederik.
Simple and reliable. Fully under your control - unlike Auto Tab Discard, which messes Firefox up if you have too many tabs.
Users: Suggest using an optional feature to indicate which tab has been discarded:
1. Firefox toolbar "hamburger menu" (a button with three horizontal lines near the top right) > Add-ons and themes, or Firefox top horizontal menu > Tools > Add-ons and themes.
2. Locate "Discard Tab"
3. tab Preferences > check: Prepend snowflake to discarded tabs.
