CCleaner 5.31.6104 erases Mozilla Thunderbird profile

CCleaner for Windows
1

I am running CCleaner on a PC running Windows 10 Pro x64 Creators version. I updated today to CCleaner 5.31.6104 and ran the cleaner. Afterwards I found that Mozilla Firefox had reset, losing my homepage and Thunderbird had lost my profile, asking me to set up my email account from scratch. No emails, no address book.

The only solution was to use Windows Restore, which got everything back. I tried the update to CCleaner again, but it lost my settings again, so something is not good about this update.

I can't see anything in CCleaner settings that might be causing this.

Thank you for confirming this. I hope Piriform reacts quickly to this problem.......at least pull this update from the download site until this is investigated.

The same problem on Firefox - https://forum.piriform.com/index.php?showtopic=48429

I got the same problem with deleting the Thunderbird prefs.js file on Windows 7 with CCleaner 5.31.610.

Hi everyone,

We are currently looking into this.

Meanwhile, if you are having this problem, please go ahead and uncheck "Last Download Location" from under "Firefox" and/or "Thunderbird" in the Applications tab.

Thanks

Can somebody help and tell me how to fix the problem with Thunderbird i.e. retrieve email accounts?

I installed new patch v5.31.6105 but there are still no accounts in TB.

This patch can't repair the damage done, only make sure it doesn't occur again.

Same problems here only I had no restore point. Oh well back to the beginning .

Blindly install updated version each time. This morning downloaded updated version, had already read mail on Thunderbird then ran the new ccleaner version and done my HD backups. Went to mail again before work and was presented with a dictionary page for Thunderbird and the create an account. Mail blown away totally. Did my backups after the cleaner so those were shot as well. Was able to restore from Friday with another laptop, but lost some mail. Backed up and tested again. Ccleaner removed all again. Uninstalled the latest version and put the previous back. Will have to test the waters from here on out with each new version. Going to be a lot of unhappy Thunderbird users with this release.

@anyuser,

if you had .6105 and have gone back to a previous version, Piriform have pushed through patch .6105 to fix the TB issue.

I was lucky to have a restore point to go back to, but afterwards I found that my original profile for Thunderbird was still intact. The profile contains emails, address books and other info.

I wonder if the "faulty" CCleaner update makes Thunderbird look in the wrong place for the profile? You can check where the profile is stored by going to "Help" in Thunderbird, then to "Troubleshooting Information". There you will see Profile Folder. If you click on Open Folder, you should see the location.

The path, in my case, is: This PC> Local Disc (C:)> Users> xxxx> roaming> Thunderbird.Profiles xxxx is your name

So if you find you have no account after the update, first check the path above. Then check the Troubleshooting information in Thunderbird to see if it points to the same place. If not, then move the profile to that location.

It's just an idea, not sure if it will work, but worth a try if you have lost your Thunderbird account and don't have a backup?

.

it's a real shame that ccleaner has changed its behaviour without telling us before! I have run ccleaner before redaing your warnings and then I have a huge problem! I will ban ccleaner for ever now!
