Local Storage Data = Firefox Offline Website Data. It does not clean it from the folder 'C:\Users\User\AppData\Roaming\Mozilla\Firefox\Profiles\user.default\storage\default.

If it did I'd give it 5 stars, so instead of 2 clicks, I go with 3 clicks with FF's built in history cleaner.

Missing an option *importante for me* : cleanup only for current website (domaine)

Great one step add-ons that save valuable time

peut très bien remplacer le fameux ctrl+shift+suppr

Works great, especially it saves the settings I made on firefox in which other cleaning add-ons does not, and I have to set up its settings every time I re open firefox.

Very useful and love the Tabs + Miscellaneous Options

Mircosoft classifies this application as harmful for the Edge web browser, which I personally cannot understand.

Does NOT remove all cookies, e.g., youtube-nocookie.com 64kb remains in Manage Data despitre multiple attempts to clear it.

"Clear Browsing Data" indicates that it has cleared everything multiple times. When I go to Firefox "Settings-Privacy & Security" I still have cookies and storage items from Google (and occasionally other sites) that must be cleared via Firefox settings.
