Firefox users, who are using the AVG antivirus in their PC, having some tough time as the antivirus is reportedly deleting login details in the Firefox browser. However, not all versions of Firefox are affected. As per complaints received from users, the AVG antivirus is hurting only the Firefox 67.0.2.

Simply put, those who are running the Firefox 67.0.2 along with AVG, will no longer be able to autofill passwords and other login details. AVG somehow managed to change the name of a crucial file in the profile folder of the Firefox browser and hence the issue. The logins.json file has turned into a logins.json.corrupt file.

On the bright side, Mozilla is fully aware of the issue and is currently working on a fix. And since the issue has been caused by external software, it’s likely that the company will work closely with Avast to address the issue.

The good news that you don’t have to wait until Firefox brings a fix. You can fix the right now by following the below steps.


  1. Launch Firefox
  2. Click on  Menu > Troubleshooting Information
  3. Under Application Basics, for Profile Folder entry, click “Open Folder”
  4. Switch to Firefox browser and choose “Exit” in the menu to close the browser.
  5. In the profile folder, if the logins.json file already exists, rename it to “loginsnew. json” and rename logins.json.corrupt to logins.json, the latter step is important.

Once you’re done with the above steps, re-launch the browser and see if it is working, and do let us know in the comments.
