  • Did Firefox suddenly forget all of your passwords? Blame Avast. Again

    Posted on June 14th, 2019 at 19:06 woody Comment on the AskWoody Lounge

    If Firefox suddenly forgot all of your passwords in the past day or so, blame Avast.

    It looks like Avast Antivirus and AVG Antivirus are both blocking the file that Firefox uses to store passwords. Your passwords are still there. You just need a new version of Avast or AVG.

    Martin Brinkmann has the details on ghacks:

    Firefox, just like any other modern browser, supports the saving of authentication information to improve the sign-in process on websites. Instead of having to enter the passwords manually each time they are requested, Firefox would provide the password when needed.

    Firefox saves the data in the file logins.json in the Firefox profile folder.

    Reports suggest that Avast and AVG security applications cause the issue for Firefox users. It appears that the software programs somehow corrupt the login.json file so that Firefox cannot read it anymore.

    Lawrence Abrams on BleepingComputer has the inside story:

    In a Mozilla bug post about this issue, Lukáš Rypáček, an engineering director at Avast, explained that the AVG Password Protection program will block a process’ access to saved logins unless the process is signed by a known and valid Firefox certificate. As Mozilla had issued a new certificate on 5/31/2019 and signed Firefox 67.0.2 with it, but AVG had not included it in the AVG Password Protection program, the Firefox processes were being blocked.

    Apparently Avast has released updates to fix the problem.
