Outstanding. Works excellently in conjunction with Cookie Quick Manager which will protect from deletion the cookies you want to keep.

This extension lacks one feature us "old school" Firefox users would like to see. It does not clear the searches entered in the search bar.

It does clear the searches entered in the combo search and navigation bar but not the additional search bar found in the customization page.

If this extension had that feature I would give it the five star rating it richly deserves.

Clicking Forget on Exit does not save Forget the last. It is not saved unless you click the Forget! button.
Anyways, Forget on Exit doesn't work at all.

It's okay but it's not as good as just self-destruction cookies

The app can't be adjusted on my phone I must use the default settings I erase my settings for a day then move it up to a week after my sites are cookies are set for their six month and year settings. but I can't do it on my 6.0.1 Android on BlackBerry Fire Fox V55, but it works well on 71.1 on my Samsung S3 with Fire Fox Nightly V57.
