[Help for a Newbie]

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

[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?
