Firefox Community Forum

Hello,

I'm building custom firmware for a Makerdiary nRF52840 USB dongle using GitHub Actions.

When I tried downloading the generated ZIP file, Firefox blocked it with the warning: "This file contains a virus or malware."

I removed the blocked download rather than overriding Firefox's protection.

The ZIP contains custom `.uf2` firmware for an embedded USB device. The GitHub Actions build passed its validation checks, and an independent ClamAV scan of the original firmware reported 0 infected files. I subsequently built and scanned an updated version, which also passed.

Original blocked build: https://github.com/flips96-art/hid-remapper/actions/runs/39094413639

Latest build: https://github.com/flips96-art/hid-remapper/actions/runs/39096517313

Latest antivirus scan: https://github.com/flips96-art/hid-remapper/actions/runs/39096868117

I understand that a clean ClamAV scan does not guarantee the file is safe.

Could someone help me determine why Firefox classified this download as malware and explain how to submit it for a possible false-positive review without disabling Firefox's security protections?

Thank you!

When I am using Firefox, which has been my primary web browser for years, I find that in the past month, in addition to opening the link that I want, a separate window with information on Alaska cruises or free shipping webpages, which I am not interested in opens. Is this happening to others, and if so, are steps being made to correct this problem. I am collecting some of the extraneous links that have been popping up,

I am using FF 158 on Win11

I noticed that apps after login are being restored with my previous session even if i close the browser and restart the browser!

ways to reproduce the problem: - Login to an app - Exit the browser, ensure the Firefox.exe is not running using Task Manager - Restart the browser and go to the same app URL. - At this point I expect the app to prompt for a password again (It does prompt for a login on Chrome and other browsers including FF 154) however on FF 158 the session is still active!

I have checked the settings in FF 158 and disabled the restore Tabs option on startup however the bug still exists.

This is a serious security issue. Kindly investigate and address

I have the notification that Firefox is being controlled by my organization and there isn't one. When I checked into it, what is listed is that Nord WANTS to install "NordVPN CyberSec.cer". I switched VPNs months ago, too. I went in and deleted it wherever you do that, but it hasn't updated in this area so it's still affecting my account. I need to update my email and it won't allow me to, for example. How can a certificate that hasn't been installed and for which even that request has been deleted, do this? And what can I do to get rid of it? Thanks!

Why provide a link to say who might see my private browser activity and then say absolutely nothing at the landing page about that subject? I an sick of that crap from all the paid by the word nincumpoops!

Hi,

Firefox 140.17.0esr (32-bit), Windows 11 23H2, trying to open https://babia.to but get a blank screen. By F12 I see this error in the console:

None of the “sha512” hashes in the integrity attribute match the content of the subresource at “https://static.cloudflareinsights.com/beacon.min.js/v4bc70e2c01a94c73b74392e4234840661791215815920”.

If I open it in Chrome 140 it opens fine. What's the issue with my FF and how to have it fixed?
