I've just started using SlimBrowser and found the UI very good - much easier for tabs than Firefox. I've now ditched Firefox from my PC and set SlimBrowser as my default browser.

But CCleaner doesn't make any mention of SlimBrowser under its Applications tab, while it still lists Firefox. Now, I guess that SlimBrowser is just a smart frontend for IE, so maybe as IE is included in the Apps, CCleaner takes care of everything. Can someone confirm this?

There maybe settings or history stuff the program itself keeps, but uses the IE engine. So, it will be cleaned when you run CCleaner. I'll have a look at it in the afternoon for ya.
