when I click on the 'Firefox' button left top corner I see nothing that says tools - where do I find tools? There is an options but only has to do with toolbar.

Press F10 or tap the Alt key to bring up the "Menu Bar" temporarily if the Menu Bar is hidden.

Use "Firefox > Options" instead of "Tools > Options" if the menu bar is hidden.

THANK YOU - I appreciate your time to help me. This is so much easier than having to close Firefox and use CC Cleaner to do it - and then having to sign back in to yahoo mail.

I do try to do CC Cleaner & the registry fixer at least twice a week and do the deep defrag once a week. I always private browse in IE and empty everything there when I'm finished using that. I used to 'private' in Firefox always, but found I had a hard time with yahoo mail when I started using that account again.

Thanks again......
