CCleaner damages the Firefox profile

CCleaner for Windows CCleaner Windows Bug Reporting

CCleaner damages the Firefox profile so that the Firefox addressbar suggestions are wrong.

Steps to Reproduce:

1. Install Firefox (use a clean Firefox profile);

2. Firefox- Go to a website (i.e. "gazzetta.it");

3. Firefox- Add this site to bookmarks;

4. Firefox- Options > Privacy, change setting from "history and bookmarks" to "history" only;

5. Firefox- Close Firefox;

6. Clean Firefox data using CCleaner;

7. Open Firefox;

8. Firefox- Begin to type the website address (i.e. "gazz") into the addressbar.

Actual Results:

Addressbar shows the suggestion for the site, but it isn't in history anymore (we cleaned history, cache etc. with CCleaner), it is in bookmarks but we configured "history" only suggestions in Firefox. After these steps, you can also try to clean the Firefox history using the Firefox built-in feature, but Firefox always shows the wrong suggestion. This happens after you use CCleaner to clean the Firefox data.

Expected Results:

Firefox shouldn't suggest bookmarks if we configured "history" only suggestions.

This issue is triggered by CCleaner, maybe it doesn't properly handle the Firefox database.

I suggest a deep review of the Firefox data handling.

Best regards :)

P.S.

The specific issue seems to be caused by the "Internet History" cleaning option of CCleaner.

ccleaner does not have anything to do with your settings in firefox. If you tell CC to clean history yes it cleans history. This is not a bug. It's working as expected. (personally I don't see any reason to use the history clean for firefox in ccleaner in your situation as firefox is cleaning it at exit.)

Sorry but that's not the point.

The point is that the history cleaning feature of CCleaner does damage the Firefox profile (probably it improperly handles the Firefox database), so that Firefox begins to behave incorrectly.

CCleaner has had this problem ever since Firefox started using sqlite files for storing the history, which I believe was with version 3.0. There's been a lot of updates to CCleaner since Firefox 3.0 came out and this bug still hasn't been fixed, so I don't really expect it to ever be.

I can confirm that this is a long-time bug...

It's easy to reproduce using your steps, so hopefully the developers will look into this.

Thanks, we'll look into this.

Thank you. I can confirm that CCleaner 3.07 still damages Firefox.
