这是我对比所有清除插件最好用的设计，建议增加一个生效后右下角的临时提示，可自动消失的提示，如：cache缓存已成功清除。(all time)

Using ramdisk as cache, and this extension works flawlessly. Please add shortcut like F12 or any keyboard.

I have tried all the other Firefox cache cleaners, and this one is the best. You can choose what to clean and how far back in time, then save your settings.

This is the best CLEAR CACHE add-on, bar none.

Unlike the other similar add-ons which clear everything, including cookies and History, this one allows you to choose individual items, such as CACHE only, or CACHE and HISTORY, or just PASSWORDS, etc..., etc...

This is a professional-grade add-on !

One click and you can clean your history.... It does what it should do and it does it well.

Unlike what Skinny Tony wrote in his review, the addon does remember the settings when reopening Firefox.
It's a simple and very straightforward addon doing its job perfectly in just one click, which is exactly what I was looking for.
