Rated 5 out of 5 stars

Love it. It's so easy just to click a button to restart firefox and preserve tabs when the memory gets a bit too large instead of having to quit firefox, wait, open firefox, choose "restore tabs" just to get to the same place. Will be glad to donate if you can make it compatible for Firefox Quantum. I downgraded to 56 just so I can continue using this, tabs mix plus and faviconize tabs. I might even jump ship to Waterfox if my favourite add-ons never makes it to firefox Quantum.
