Firefox Community Forum

A couple days ago when I opened Firefox, I immediately started getting pop up messages saying I had viruses. If I clicked on REMOVE VIRUS, it tried to get me to sign up with McAfee. I cannot see my full screen due to all the pop up screens. My MS Defender virus protection is not identifying any viruses.

For the past few days I have been getting 'pop-ups' showing various Error messages; e.g. 'Trojan virus found'; 'Trojan Detected'; 'System alert'; 'Attention'; 'McAfee virus found'; 'McAfee license has expired'; plus others. These messages are followed by various instructions followed by "via (string of characters).natrixa.co.in. I have run my security software (Norton 360) several times and no virus or other problems have been found. These 'pop-ups' are exceedingly annoying. Any idea how to get rid of them? Thanks in advance for any help. Regards John Cundy

For some time now I have been unable to see (or post) any pictures directly in my chats on Twitter (X). I can see and they will post in the main feed but not in my DM (chats) on Twitter. I have no issues on any other website I use. When I inspect the page I get this error: "Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://proxsee.pscp.tv/api/v2/loginTwitterToken. (Reason: CORS request did not succeed). Status code: (null)." If I post a picture in the main feed I can then send it to the chat and it is fine, but I can not post it directly to the chat! If someone in my chat post a picture directly to the chat then I can not see it, but if they repost it from the main feed then I can see it.

I am running Windows 11 & Firefox 154.x I have disable Badger, NoScript and ZoneAlarm (tho not all at once) I have tried installing a CORS workaround plug in (two different ones). None of these thing have helped.

Couple more pieces of information - I don't have this issue on my work laptop or my iphone app. Something on my computer is doing it - but I can't for the life me figure it out.

When I open my website, pvamarkets.com, I see a Cloudflare page that says:

“Suspected Malware — This website has been reported for potentially distributing malware.”

This is a legitimate e-commerce website. After the warning appeared, we completed a full server-side security check. We checked the website files, database, cron jobs, access logs, error logs, and file-delivery system. We did not find malware, executable files, unauthorized code, or signs of a server compromise.

Our website only delivers plain text files to customers. It does not host or distribute Windows executable files.

I understand that the warning page is branded by Cloudflare, but I am posting here to confirm the following:

Is this warning generated or influenced by Firefox or Mozilla Safe Browsing? Can Firefox cache an old security warning after Cloudflare removes it? Is there any Firefox security report or blocklist entry for this domain? What steps should a website owner take to confirm that Firefox does not classify the domain as malicious?

The warning appears before visitors can access the website and causes serious trust and access problems.

I have attached a screenshot of the warning page.

A Google Safe Browsing page now stops my going t0 any links in my Mail.com emails, & it says Firefox is blocking this, & it doesn't let me give permission to go to any of those linked pages I FULLY TRUST ! Mozilla Firefox is my default browser in Win 11

i keep getting annoying popups from this websites saying virus detected, system error, download this antivirus etc. These are their URLs: isistelies.co.in; 37yito.isistelies.co.in They won't stop popping up! How do I block them?

I'm blaming the latest Firefox update from a couple of days ago, since this problem only arose yesterday. Now cut off from reading and following news that I really want to receive.

This is what I get when trying to access links within a few of the websites that I regularly access for links to articles it posts:

The site ahead may contain harmful programs

Firefox blocked this page because it might try to trick you into installing programs that harm your browsing experience (for example, by changing your homepage or showing extra ads on sites you visit).

Advisory provided by Google Safe Browsing.

As of yesterday, I have a message on Inspire.com which says Opt-Out Signal Honored It even says that before I log in. They are checking at their end, can you please help me? This is the only website that I receive this message.

Also, I am receiving more and more pop-ups that say WARNING SECURITY RISK "Be careful. Something doesn’t look right."

"Firefox spotted a potentially serious security issue with tracenep.bidprism.com. Someone pretending to be the site could try to steal things like credit card info, passwords, or emails." Some are websites I use, some are not. I don't remember adding this to my list or changing any of my extension settings. Please Help.

Thank you very much.
