I see that you have 4.3.7 ([email protected]) installed.

Are you using the Xmarks Sync service or the built-in Firefox Sync (or both)?

Could you post a Sync log to see if there is a problem? You can check the about:sync-log page via the location/address bar to see if there are error logs available.

You can upload a recent log to this website if the log is too big to put in a reply.

Make sure that you allow cookies for the accounts.firefox.com domain if you aren't allowing cookies generally or use the 'Ask me' cookie setting or use extensions that deal with cookies.

The Sync version used in Firefox 34 and later uses the password manager to store the name (e-mail) and password to be used to connect to the Sync server. The chrome://FirefoxAccounts entry in the password manager stores the authentication data (kA and kB) in JSON format. You can check this in the Password Manager.

Try to delete the signedInUser.json file in the Firefox profile folder and delete the Weave folder (Sync was formerly named Weave). If that isn't enough then delete the prefs.js files to reset all prefs and maybe also delete the compatibility.ini file to reinitialize the profile.

You can use this button to go to the currently used Firefox profile folder:

• Help > Troubleshooting Information > Profile Directory: Show Folder (Linux: Open Directory; Mac: Show in Finder)

Thanks for your response. After posting this problem, I ran Malwarebytes Anti-Malware and quarantined several PUP items from Conduit Ltd. At boot-up this morning, there were no further sync error messages.

To provide additional info to your post:

• I use Xmarks to store passwords in a separate location from Password manager, I use Firefox Sync to sync between devices.

• The error log is posted at pastebin and will be stored for one day

• Cookies are allowed

• I can see the entry in Password Manager. If malware had not been the issue, would you advise deleting the entry or merely continuing on to delete the files mentioned?

If it is working fine now then there is no need to follow the above posted steps. You can consider to perform them in case the problem returns.

This seems to only occur when the computer has gone to sleep. When I wake up the computer and navigate to a new web page, I get the message. Clicking on the offered Preferences button clears the message.

Here is the latest synclog at pastebin.

Based on this info, is the next step to delete signedInUser.json file in the Firefox profile folder and delete the Weave folder (Sync was formerly named Weave)?

You didn't provide us with the URL to your pasted log at the pastebin website. Once you hit Send the URL in the Location Bar will change to "your" unique URL for the message that you post.

Sorry, here's the latest error log. Again, error message occurs when waking up the computer. It will stay at the bottom of the page unless you press "Preferences" or the "X"

Thanks for your help,

Do you see the entry with the Sync (Firefox account) credentials in the Firefox Password Manager like I posted in my first reply?

• Tools > Options > Security: Passwords: "Saved Passwords" > "Show Passwords"
• chrome://FirefoxAccounts

Can you log in here?

• https://accounts.firefox.com/settings

Did you try to delete the signedInUser.json file in the Firefox profile folder?

Con-El, Thank you. Yes I have always seen the Firefox Sync credentials, and I am able to log in to accounts.firefox.com/settings.

This morning I deleted the signedInUser.json file in the profile folder, rebooted Foxfire and signed into websites. I left the PC to go to sleep. At wake-up two hours later, there was no error message.

I note that the signInUser file was not re-created when re-booting Firefox. So at this point, this looks to be solved.

Thanks,

 Rita
