Practically essential. I'm baffled it's not a built-in feature by default.

good

My history was very old, probably 10+ years. I shrinked everything to the last 3years (1095days), which took very long the first time, firefox was running on 100% for 5-10min. But now it looks good. It is not very transparent how many history entries were deleted, though.

Can we have option for clean the history by some setup time.

GOOD

Nice addon, thanks for the job! The settings page could use a bit of a design refresh maybe...? And I'd love to have an history (ah ah!) of what's been done, even just to know that this week, this many items have been deleted, or that it run without deleting anything... A bit of logging to show that it actually does something.
