Firefox does not clear all recently closed tabs & windows

[tkrojam]

For Firefox 17, "Clear recent history"+"Everything"+All boxes selected sometimes does not clear all history of recently closed tabs & windows . I really don't know why but somebody said some of my installed plugins may make this error occurred.

Anyone knows the reason?

You could go on Mozilla issues and see if a bug has been reported. For here, I would ask a Mod to move your Post to Browsers and Email forum as you'll get more users of FF reading there.

Hello, I found one add-on which clears all history of current web browsing history "Clear History". Hope it will work for you.
