Why am I receiving repeated warnings from Malwarebytes about blocking every-day websites due to a "Trojan"? The sites include Gmail, Ancestry.com, Newspapers.com and others.

The report warnings are being generated by the Malwarebytes program on my PC. They are confusing to me. I am running Windows 11. The warnings are being logged by the Malwarebytes program in the "Web Protection" section of its "Detection History" web page. In every instance, the log reports are the same: in the URL identification column there is no identification of the URL, only repeated instances of "N/A"; the IP address is identical for all the warnings; the port is always "0"; the file column alternates from "C:\Program Files\Mozilla\Mozilla VPN\Mozilla VPN.exe" to "System" and back again to "C:\Program Files\Mozilla\Mozilla VPN\Mozilla VPN.exe"; in the final column of the log, the Date column, the warnings began last evening, Monday the 12th, at 6:50 p.m. and have now extended to to a total nine warnings.

Even as I was writing this communication, the Malwarebytes warning popped up on my screen, telling me that this website and this web page are blocked due to the presence of a Trojan.

Is my PC infected? The Malwarebytes "scan" reports no "detections." I am at a loss.

My Mac shut down unexpectedly. Upon rebooting the newest version of Firefox - 138.0.1 was installed. All of my bookmarks have disappeared. I tried to restore from a backup but when I hit restore in the manage bookmarks window it says "choose file" but it lists no files to choose from. I found multiple backup files by accessing my Firefox profile via finder. However when I try to open them with Firefox it displays a blank page and nothing in the bookmarks tab. Is it possible that the bookmark files have also been deleted from the backups as well? If not, how do I transfer these files to the active bookmark tab in the menu bar other than using the restore function which offers no files to choose from?

I am experiencing an issue with the Keeper browser extension on Mozilla Firefox. Despite configuring all related settings appropriately, the extension consistently locks out every time I close the browser.

To troubleshoot, I have:

Verified that the extension is enabled and fully allowed in Firefox’s Extension settings.

Ensured that Keeper is whitelisted in every possible relevant setting within the browser.

Checked that the "stay logged in" or persistent session options are correctly set within Keeper’s own configuration.

Confirmed that no conflicting privacy settings or third-party add-ons are interfering with the extension's functionality.

Despite these measures, the extension does not retain its logged-in state upon browser closure. This behavior suggests a persistent session issue not aligned with the user-side configuration.

I would appreciate guidance on how to resolve this.

For unknown reasons I cannot load ATT mail or Myatt. I have turned off virus protection and adblock, same result. Not sure when this started. Windows 11 Home. Dell XPS desktop, i9,

Be descriptive. Saying “playing video on YouTube is always choppy” will help us understand the issue better than saying “something is wrong” or “the app is broken”.

Hello Firefox Community,

I'm experiencing a strange issue with my website, https://www.hostgrap.com.

When I visit the site using Firefox, I get the following error:

Bad gateway Error code 502 Visit cloudflare.com for more information. 2025-05-14 04:02:47 UTC

Browser: Working Cloudflare: Working Host: Error

However, the same website works perfectly fine on other browsers like Chrome, Edge, and Safari.

Troubleshooting steps I’ve tried in Firefox:

Cleared cache and cookies Disabled all extensions Cleared DNS and HTTP cache via about:networking Checked proxy settings (set to system default) Tried Private Window Flushed system DNS Updated Firefox to the latest version

None of the above resolved the issue. The error appears consistently only in Firefox. I’m using Cloudflare for DNS and reverse proxy, and the server is working as expected for all other users/browsers.

Additional Info:

OS: Windows 10 Home Single Language Firefox Version: 138.0.3

This issue happens even after disabling all add-ons

No custom rules in Cloudflare specifically targeting Firefox or its user agent

Is there something Firefox-specific that could be triggering this behavior with Cloudflare or my server?

Thanks in advance!

Why don't I see the review checker on Amazon anymore, I liked it but it seems to be missing. I tried following the instructions but I don't see the mentioned icon that I am suppose to click on

firefox stalls on ubuntu and the OS says it is running but I cannot or don't know how to restart/reset it from the terminal. A reboot of the computer solves the issue but I have to re enter the bios password etc. Is there a simple solution?
