Hi ShirleyM:
Glad to hear you were able to recover your Firefox bookmarks. I assume you followed the instructions in the YouTube video at How to restore Firefox bookmarks you mentioned in your 11-Jan-2026 post in NicolaB’s I accidentally cleaned Firefox bookmarks!.
Instructions for downgrading to CCleaner v6.39 are posted in nukecad’s 11-Oct-2025 topic How to Roll Back from v7 to v6.39 to downgrade to CCleaner v6.39.
I’m not sure what specific feature you mean by ‘save sites that were already logged on to” unless you are using Firefox’s built-in Password Manager to automatically fill usernames and passwords for logins, but in the previous CCleaner v6.x you can prevent CCleaner from cleaning items like cookies, passwords, site preferences, browser history, etc. in Firefox by disabling those items in Custom Clean ** …
… and/or go to Options | Cookies | Cookies to Keep and choose important “Cookies to Keep” if you use CCleaner to clean your browser cookies. Unfortunately, the “Cookies to Keep” feature does not work correctly in the current CCleaner v7.03 - see hmsccleaner’s 18-Dec-2025 topic CCleaner V7.3 “Keep Cookies” from trusted sites does not work.
** NOTE: I stopped using CCleaner to clean my default Firefox browser a few years ago after a bug in CCleaner damaged several Firefox browser extensions (see circcc’s 01-Jul-2020 topic Problem with Firefox 79) so all options for cleaning Firefox are disabled in my CCleaner v6.39 Custom Clean settings. Instead, I use my built-in Firefox settings at Privacy & Security | History to automatically clear most of my browsing history (e.g., cookies and site data, etc.) each time I exit Firefox - see the Mozilla support article Delete browsing, search and download history on Firefox.
