Hi everyone and mozilla

Hope you're all having great day and just wanted to give some suggestion on how to improve more of Firefox to make it more secure and better.

Here are the suggestions that would make firefox better:

1. Implement stricter per-process sandboxing to improve isolation and minimize the impact of compromised web content processes.

2. Introduce advanced script and traffic behavior analysis for detecting malicious JavaScript activity, suspicious network patterns, and exploit-like behavior.

3. Strengthen extension behavior monitoring by automatically flagging add-ons that request excessive permissions or exhibit unusual data-collection patterns.

4. Develop next-generation cookie isolation using automated, context-aware segmentation to prevent cross-site tracking and leakage.

5. Add built-in DNSSEC validation so Firefox can independently verify DNS responses and reduce the risk of DNS spoofing.

6. Provide a threat visibility dashboard giving users insight into loaded scripts, blocked trackers, fingerprinting attempts, and abnormal resource behavior.

7. Enable an automatic hardened mode for public networks that activates stricter policies—such as mandatory HTTPS, limited API access, and aggressive tracker blocking—when an untrusted WiFi network is detected.

Hope this really helps, as a fan of using Firefox. I want Firefox to become better and more secure and more durable (only using Firefox everyday)
