As you say it may be an issue with Catalina. Unfortunately we don't have many (any?) knowledgable Mac users posting here. If you can run CCleaner Mac in debug mode the logfile may help pinpoint just where it is hanging. https://support.piriform.com/hc/en-us/articles/204390300-Run-CCleaner-for-Mac-debug If you let CCleaner eventually open then you should see a large time gap in the log for the process it got stuck at.

That's one reason for using CCleaners Custom Clean rather than the browsers own cleaning. CCleaners Custom Clean gives you more control over which cookies to keep and which ones to zap than (most) browsers do.

Windows defragment/optimise is still active and still running, installing Defraggler does not turn it off. But if you have already run Defraggler then Windows defragment/optimise may well decide that another optimise is not necessary. It's not that unusual to see that it hasn't optimised for days or even weeks/months, it analyzes on a schedule but only optimises when Windows thinks it is necessary. I usually run Defraggler weekly and my Windows defragment/optimise hasn't done my C drive since 11/09/2020 (I must have forgotten to run Defraggler that week). If your computer is not switched on when Windows defragment/optimise is scheduled to analyze then it will simply try again at the next schedule point. You can change that schedule in Windows defragment/optimise itself.

Is this before or after you have entered your licence key and name? You need to enter you key/name before clicking the 'Register' button. I don't know why the button would not function but the first suspicion would be that the install may not have been complete. Try uninstalling your CCleaner then downloading the 'Slim' installer from here, install it and then retry registering by clicking Options>About>Upgrade to Pro. https://www.piriform.com/ccleaner/builds See this for information about problems when registering CCleaner: https://support.piriform.com/hc/en-us/articles/204043844--Problems-activating-or-registering-CCleaner-Professional

It is normal normal that some things come back again straight after cleaning. Browser syncing is one thing that will do it - even if your browser is not open/active it may be 'pre-loading' synced information and cookies. All those cookies seem to be from google. Are you using a Chromium based browser (that is synced)? You could check if that is what is happening by disconnecting from the internet (pull the ethernet plug out of the computet and turn off wifi), run CCleaner, wait a minute and run it again.

You have replied to a year old thread. Your information about defragging SSDs is also out of date for modern SSDs, although it was valid for early SSDs which had shorter write lifetimes. Windows own built-in defragmenter now ocassionally defrags SSDs automatically on schedule.

I'm not sure why the OPs local OneDrive directory is being displayed (without styling) as a browser page. Maybe the Firefox install had put something in OneDrive that the CCleaner browser was trying to display? When you install Firefox as the default browser it usually opens a welcome webpage. So if the OP had not made Firefox the default during the install then perhaps tried to open whatever browser was the default, in this case CCleaner Browser. But the local directory is certainly being displayed (without styling) in a browser, with the pathname in the address bar. I can do that manually in Firefox and the styled page is displayed as the screenshot below. The main difference I can see in the pathname is the tripple slash in my Firefox as opposed to a pipe it the OPs screenshots. But that could just be a difference between how the browsers display the pathnames of local directories in the address bar?

Here is a screenshot of one that just happened to me on Android, (sorry it's a bit large) as you can see the "Index of ...." is your first clue to what has happened. A refresh of the page displayed it correctly.

Yes you can get email notifications. At the top right of any page click on your name and choose 'Account Settings' from the menu that drops down. On the right of the screen that comes up choose 'Notification Settings'. You then have a page where you can set up notifications for different things and whether/when you get an email about them.

No, it cannot run when your PC is turned off. If you are at your PC then you should see an icon appear on the taskbar/System Tray when CCleaner is running a scheduled clean. (But it may not be there for long). You could also do an 'Analyze' shortly before and shortly after the set time to see the difference that it has made.

That kind of thing happens occasionally in any/all browsers, usually simply refreshing the page displays it as it should be. To be more technical it happens when for some reason the CSS (Cascading Style Sheets) webpage styling is not loaded correctly by the page. So you just see the 'raw' page with no styling applied, and some of the background coding and other unstyled stuff will be visible. (The "Index of....." for instance is background stuff that you wouldn't normally see on the styled page). As said usually a simple page refresh cures it, if not try closing and reopening the browser. (I find it happens more often on Android than Windows and I usually have to close/re-open the browser on Android). But if for some reason the CSS is corrupted, missing, or not being called correctly, then it will take action by the page owner to correct the problem.

The point remains that these default search engines are not doing anything at all unless they are ticked and you use the Firefox searchbox. They are not loading, taking up memory, or doing anything else, unless/until you call them from the Firefox searchbox. If you don't want to see them then hide (remove) them from the One-Click search engines and forget them. (Or take the Firefox searchbox off your toolbar altogether).

Does that still apply to Edge Chromium though, or only to legacy Edge? EDIT- Apparently not. There are plenty of questions online about why the 'improved' Edge Chromium can only play at 720p whereas Legacy Edge could do 1080p.

Easy, just untick them in Firefox Settings/Options and the Firefox searchbox will only use google. Or: Don't use the Firefox searchbox at all and set your Firefox homepage to google or whatever search you do want to use. (PS. 'New Tab Homepage' is a useful Firefox add-on if you do that). And (at least for now) don't bother disabling them with CCleaner, because Firefox will simply re-enable them again. I guess that mozilla are somehow making money by having them enabled by default?

Apparently Firefox also used to regard these search engines as extensions/plug-ins and they could be removed from the Add-ons manager. You can't do that for the search engines anymore, and just when Firefox stopped letting you do that I don't know. PS. The talk about BitDefender here is confusing things; BitDefender is not a search engine and not a defualt in Forefox.

This is exactly what we are saying; Firefox is enabling these search engines by default - and you can't stop it doing that. If Firefox is closed then you can 'disable' them with CCleaner, but then Firefox just re-enables them again. Nobody but Firefox/Mozilla can change that behaviour. (I've searched online but have yet to find anyone who has managed to totally disable them permanently). It's not something that CCleaner can change, Firefox would have to stop enabling/re-enabling them by default.

Afaik you have to get a licence for CCleaner Android through the playstore. It's a google thing.

My advice is as above - Don't use Health Check, only use Custom Clean and either clean no cookies at all or work out which cookies you need to keep - with the help of the linked article.

Are you using Health Check or Custom Clean? It sounds that what may happening is that your email preferences for the sites affected are being saved as cookies, and CCleaner is clearing those cookies. In that case then Health Check will always clear them, but Custom Clean can be set not to clear them. To do that you have to use Custom Clean only and either tell it not to delete any cookies at all, or tell it to 'keep' the cookies for those particular sites. See Options 1 & 2 here for details of how to do that: https://www.ccleaner.com/docs/ccleaner/ccleaner-settings/choosing-which-cookies-to-keep

Have you tried the other suggestions? If you have and it's still not registering then you need to contact support to check your purchase and if there is something wrong with the key that you have been sent. It's not something that we can do on the open forum. (For security/privacy we can't see licence information here). You should email them at: support@ccleaner.com If possible send your request from the same email address that you used when registering CCleaner. (If that's not possible then noting that registered email address in your request, if you can, will make it easier for them to find your account). You should get an automatic acknowledgement by return email that your request has been received and is in a queue for action, if you can't see one then check your email spam folder.

Yes it is designed to clear your drives and make the deleted files unrecoverable. It will not let you completely wipe the OS drive for obvious reasons but will clear all but the OS. More info here: https://www.ccleaner.com/docs/ccleaner/using-ccleaner/wiping-free-disk-space

For info could you tell us: What Recuva version are you trying to register? What version of Windows are you using? Which AntiVirus are you using? And just to be sure where did you purchase Recuva from, I assume it was the official website? Common registration issues are: Make sure that you are connected to the internet. If typing in the key then be careful not to mistake letters and numbers. eg. 'S' and '5'. (I don't think Recuva keys use letters anyway) If you are copy/pasting the key from the confirmation email then is there a leading space or trailing space after you have copied it over? If so then there shouldn't be. Are you copy/pasting the name as well as the key? It needs to be exactly the same name that you used when purchasing. PS. We have known people to make typos in their name when purchasing, so they then have to use the same typo when registering. If you are still having problems then check if your AntiVirus is blocking the connection to Piriform/Avast servers? Try disabling your AV before registering. Try installing in Windows Safe Mode with networking. See also the following article: https://support.piriform.com/hc/en-us/articles/204044094-Problems-activating-or-registering-Recuva-Professional-

I think you have to bear in mind the reason (philosophy?) behind CCleaner is to clean your computer of junk, including your browser history/cache/cookies/etc. If your browser syncs automatically then CCleaner, or the CCleaner Browser can't do that because it will all be automatically synced back from the browsers server.

I don't use it, (I mostly use Firefox with MBG for extra security). And I think that may be the problem here. And I think that it's valid criticism. This is a user help forum above all else, so that users can help each other. With some input from Piroform staff when needed. If the usually knowledgable CCleaner users are not using the browser then they (we?) can't help with it. I have flagged this thread up to the staff.

The search engines themselves are not actually 'stored' on your PC, they are way too big for that - but Firefox (or any browser) links to their database(s) when needed. Quite a few .json, and other, files in the user profile seem to have links to them. So I don't believe that being able to totally disable them would save much space or speed up your browser anyway. Unless you tell your browser searchbox to use one or more particular search engine(s) then it's not going to link to their database in the first place. You can untick them all in Firefox. In which case the searchbox seems to default to Google, it does for me, even if Google is unticked in about:preferences#search. TBH many users use their chosen search engine webpage for searches rather than using the browser searchbox anyway. (I don't usually even have it on toolbar). PS. It is interesting to see from the screenshots that Firefox gives you different 'default' search engines depending on your country. For instance here in the UK we get 'Chambers (UK)' as well as the standard Google/Bing/Duck Duck Go/etc. and notice that the Amazon engine is country specific in each of the screenshots posted on this thread.
