Yes, Its a similar system as "keep history up to specified number of days". Or it can do by manually and this extension have to assist more fixed alert. So make it action to clean automatic at specified web based links. So that I can keep other links in history ! If not need, the listing will empty.

This is very easy to use History Cleaner for Firefox with just one-click.

It says history will be deleted after about a minute of no activity on Firefox. Very vague.

1. What is no activity? If I'm streaming a radio station, is that activity? If an app is constantly going out to look for new messages or something is that activity? If I run multiple profiles, must they all be inactive?

2. I would much rather be able to
a. Turn off the automated deletion (ON/OFF, not just setting days to ZERO).
b. Have a button to manually initiate the deletion.

C'est une bonne application
