Works as it should and the fact that it saves the last tabs it archived is really neat. This addon has helped make the jump from Arc to Zen. 10/10!

After pc reset i chose not to re-install this addon for a while. But realized soon i cant live without it :)

It won't save changes to settings, and the default ones are unfortunately pretty awful.

UPDATE to UPDATE: found the culprit, and it wasn't this add-on.

I am a really bad tab collector, because it takes far far too long to Ctrl-D, add tags, and save (NOT!). Dustman is good incentive to do the necessary work.

It's missing a counter on the icon which indicates the number of binned tabs though as sort of an indicator to do something; a notification popup is not necessary but .. some might want it. I could also use a restore-all options from the bin - the default bins tabs from 20 minutes old, and delete them when you exit. If you have a significant number of tabs open when you install it you will lose almost all of them when you close the browser.

You don't need hundreds of tabs. Get Dustman.

Pretty good but I would like to see a whitelist in a future update.

It works very well. Great work! Keep going!

.

I need this feature, but this Dustman is a madman. As soon as I installed it, it closed 450 tabs and remembered exactly 0 of them. What the heck? How about some more sensible defaults or a soft start, or at least a limit to how quickly it can close tabs (say, one tab every 5 seconds)?

Also, I'd like to be able to lock tabs that I don't want to be automatically closed.

Does what it says. I do wish the default was not so short however, I had well over 1000 tabs open when I installed it (including ~20 i was using today) and it just immediately closed almost all of them. This is sort of what I wanted, but I would have liked to keep the ~20 I had opened today. I'm using tab tree so this is sort of reasonable. I'm aware that I am an outlier, though.

Appears to work, just after install. I configured it to clean up tabs after 2 weeks, with a minimum of 40 tabs. Thanks for the extension!

EDIT: 3/7/23

This is still a very annoying problem 5 years later, I've had to reinstall all my plugins a few times in the past year and every time it breaks my workflow badly.

My personal settings are:

delay: 1440 minutes (1 day)
min tabs: 20

I only wish I could set them before the plugin gets triggered after install.

After updating of FF to v56 and Dustman to v.2 it doesn't remove tabs from the closed tab lists when you reopen them. Also, in the settings for the max # of closed tabs disappeared. My system is Linux Mint 18

update.
Thank you for the answer. Can you make the max # of tabs selectable? I usually set them 100 or 150, but in the new version is is unclear how many are stored.

To store all closed tabs can be inconvenient and will lead to storing obsolete links.
