Help for a Newbie

I have just downloaded the free version of CCleaner for Mac. I have installed it, and clicked on Analyze. Now it shows a list of what it will be cleaning. I use Firefox as my main browser - but it is not shown on the list. I use Safari sometimes, and Safari is shown. (see screen shot below). Why has it not included Firefox??

Also, I use a VPN - will this be affected?

Please - anyone - can you help?

Your screenshot shows the Mac OSX tab, click on the 'Applications' tab and Firefox should be shown there.

Oh, duh!! Why didn't I stop and think a bit more! Thank you - found it.
