The only information, Mozilla gives me, is the timestamp where the tab was closed. I could add a feature which restores tabs that were closed "close to the recently closed tab". But I found that Firefox seems to be very flexible about how long it takes to close a tab. It can take 100ms but it can also take over 1 second.

I can make this an optional feature, disabled by default. Then the user can try different values for the time period by himself if he wants. But nonetheless: This shouldn't even be here. PLEASE: Always suggest features using GitHub!
