On Windows 10 with 64-bit Firefox, after updating from version 144 to 145, some local HTTP-only servers stopped working and became inaccessible. When I enter http://<local server name>, after a few seconds it automatically changes to https://<local server name>, and since no HTTPS service is running, it ends with a “Server not found” page. It seems to be related to DNS — accessing http://<IP address> works fine.

I tried a clean installation with a new user profile, but it didn’t help. Downgrading to version 144 fixes the problem, but at the cost of losing the user profile (which is a disaster). I also tried to check the HTTP-only settings (which I’ve never modified), but that didn’t help either.

Is anyone else experiencing the same issue?

I read that your new CEO is pro use of AI and doubling down on wanting to implement it. Meanwhile the literal main reason most people I know to use Firefox is that it doesn't have AI slopware. I really urge anyone capable of doing so to help reconsider a decision that is going to let down long-time users such as myself. It is getting harder and harder to avoid data leaks and security risks, and until now, Firefox seemed to have been the best browser for these purposes. I don't want to switch, but if you do this, I will have to.

I've purposefully used the environment variable to disable the security sandbox.

How can I acknowledge and hide the persistent warning? Is there any about:config value for it?

Thank you!

In the last 4 or 5 days, I have been besieged by pop-ups from a scam website (I imagine) called giuyt.co.nz asking me to renew my norton subscription or telling me a virus has been found or a trojan detected. None of this is true. I have run scans on my system and there are no viruses and no malware. I have been into programs and deleted one or two programs i dont use, I have cleared my cache I have been into notifications and cleared that. Nothing I can do stops this avalanche of pop-ups (about 1 every 2 minutes). Can anyone help me please?

My Firefox on iPhone has a malware that pops up a box urging me to call a phone number (which I won’t do) about a payment. It has Cancel and Ok buttons, both of which trigger another box from the dialer containing the same phone number. I cannot get to the FF settings or escape from that page because the pop ups immediately come back and reload the page. The site looks like appleinstantsupportpays[.]z13[.]web[.]core[.]windows[.]net. All of the online advice relates to FF on Windows or Android. How do I clear the malware from my phone?

I was asked to 'Allow Chatgpt.com to store data in persistent storage'. Would that add on the risk of having my data being more exposed and kept by stakeholders not of my own choice?

Firefox detected a potential security threat and did not continue to myccp.ccp.edu. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

I have received 3 system alerts, all from Mozilla Firefox (I use Firefox as my default browser). 1) System is infected!---click on d45n9f8ko90s738b610.gsx-protect.co.in 2) ZEUS.2020 Trojan detected--with same directed site 3) System Alert!---with same directed site.

I use McAfee as my security system. They recommend going to Firefox settings and disallowing random site connections. How do I get my system running again.

Latest McAfee scan shows 45 entries deleted and 2 browsers reset

Dear Mozilla Support,

I am experiencing a serious issue with Firefox on my iPhone. The app activates normally, but after a few hours it becomes inactive on its own, and my browsing data is no longer saved. I believe this may be related to a security or phishing issue.

My cybersecurity services (including McAfee and Bitdefender) have notified me of potential phishing attempts, data access risks, and suspicious browser activity. I have reported these issues to my security providers, and they have opened case IDs to investigate further:

- McAfee Case ID: 03203372 - Bitdefender Reference: 1010231778

Due to these ongoing issues, I would like your team to check whether there’s any unauthorized activity linked to my Firefox account or app. I rely on Firefox daily and need this issue resolved as soon as possible for safe browsing.

If possible, I would also like to request that my Firefox browsing profile be locked or protected against unauthorized tampering, auto-deactivation, or interference by malicious software or attackers.

Please let me know what steps I should take, or if you need any further information from me.

Sincerely, Mod's note: PII removed

Dear Firefox Support Team,

I hope this message finds you well.

My name is Mohammad Kamal Borojerde, and I’m experiencing serious ongoing security issues while using Firefox on my iPhone 13 Pro Max. I am a delivery driver working for Deliveroo, and my device is being targeted through remote hacking methods. I suspect that some malicious actors are using apps I’m not aware of to interfere with my internet, GPS location, and even stop delivery tasks that the company sends to my phone. This has significantly affected both my work and personal life.

Despite installing multiple security applications including McAfee (Reference No: 03203372) and Bitdefender (Reference No: 1010231778), my browsing remains unsecure, and settings keep getting changed or disabled without my consent. I believe attackers are also bypassing or disabling Firefox protections on my phone.

I kindly request Firefox’s security team to investigate this matter seriously. If possible, please help me: 1. Lock down or secure my Firefox browser fully. 2. Review any unusual activity linked to my device/browser. 3. Suggest any specific configuration settings that can protect me against remote access or phishing.

Here are my associated emails: Mod's note: PII removed

Thank you for your attention and assistance in this urgent matter.

I log into a secure web account, use user ID and password, go through 3 rd party verification and gain access.

When I logout it takes back to the sites Home page.

If I decide to login again by using the login icon the website immediately logs me backin with No requirement for user ID, Password or 3 rd party verification.

I am trying to determine is Firefox holding this information (User ID, Password and Third party verification code) and auto logging me in or have I not really logged out.

If I completely close Firefox this does not occur.
