So I had Mozilla account with Syncing Enabled before I reinstall windows (I had only Zen browser on my pc), and after reinstalling windows I downloaded Zen and got in my account, but after pressing syncing there is no passwords, no history, no bookmarks, literally no data that I had before, does that mean I lost all my data?

To the Security and Privacy Compliance Team: I am formally reporting a severe security breach affecting my account(s) and digital environment. Despite strict adherence to security protocols—including the use of two-factor authentication (2FA), non-reused/secure passwords, and active monitoring with Malwarebytes—my environment has been consistently manipulated by unauthorized automated processes. Summary of Compromise: This is not a case of user error. My environment shows clear evidence of session token hijacking and automated configuration tampering. Specifically, my sessions are being forced into unauthorized linkages (e.g., Google OAuth backdoors) that I have explicitly revoked. Technical Evidence of Interference: 1 System-Level Artifacts: My browser instances (Safari/Firefox) have been rendered non-functional (failing to load pages) for an extended period, yet these applications continue to generate "browsing history" and metadata. This metadata is fraudulent—it is machine-generated output, not user-initiated activity. 2 Unauthorized OAuth Linkages: I have documented instances where 2FA-secured accounts were bypassed through the injection of secondary identity tokens (linking to an ainsleyhenn2024@gmail.com identity I did not authorize). 3 Malwarebytes Forensic Logs: I have attached logs from Malwarebytes, which provide objective, non-tampered evidence of blocked connections and attempted malicious interference that occurred simultaneously with the "bizarre" browser behavior I have witnessed. 4 Credential Bypassing: The behavior observed indicates a bypass of standard authentication flows. This suggests either a compromise of the authentication delivery service (the "Mail app" shell hijacking) or the deployment of a corrupted/compromised version of your software. Formal Request for Forensic Audit: The persistence of this activity suggests a systemic flaw or a compromised session pipeline. I request a Session Token Audit to identify:

The specific IP addresses and device fingerprints that initiated the unauthorized linkage of the Gmail identity to my account.
The OAuth scope granted during these automated handshakes.

Offer of Facilitation: I am documenting these issues in detail and have retained all relevant diagnostic logs. I am prepared to share these logs to facilitate a forensic examination, provided this inquiry is escalated to your Security or Data Integrity team. I am seeking a resolution that addresses the systemic failure to protect my data and ensures my account integrity is restored to a trusted state. Please advise on the secure channel for submitting this technical evidence for a full forensic review.

Just updated Firefox desktop (Win 10 with ESU) to 140.10.0ESR and now every site I try to access gives

Secure Connection Failed An error occurred during a connection to www.google.com. PR_CONNECT_RESET_ERROR Error code: PR_CONNECT_RESET_ERROR

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem.

Sites were all working fine literally right before. No other changes at all. Have restarted a few times. Have disabled antivirus and adblocker extensions. Same problem including at google.com and even firefox. Note on the About Mozilla Firefox window says " Failed to check for updates". Also cannot even use the links there to go to What's new or Firefox help etc. (Gives Secure Connection Failed error). No proxy server. Have tried turning anti virus completely off. Just a combined modem/router -- basically vanilla.

Firefox is my primary browser so this is extremely disruptive. I am using Edge to access sites and post this.. though curiously enough I noticed it gave some error when checking for updates. Do not want to do anything there or will lose complete access.

Any suggestions .. or how to go back to a previous version, if necessary. Need a workable connection to file taxes next week so this is important. Thank you.

Firefox is diverting known safe sites stating they are dangerous and then redirects to http://147.45.69.3/ which in turns send you to other sites. It also happens in Chrome so they must use the same system. The sites are totally safe I use them all the time but lately get redirected and it is getting very annoying

Please dont turn firefox into AI slop. The browser does not need "AI" shoved into it and currently the lackthereof is one of the only things keeping a large user base with firefox. Please please don't cram more AI down our throats. Again, no one wants this shit except MBAs.
