I just updated my Mozilla VPN to version 2.40. Now, whenever the vpn is started, Windows reports that nvspcap64.dll is not designed to run on Windows or it contains an error. Error status 0xc0000428. I have tried uninstalling and reinstalling to no avail. I restored the nvspcap64.dll from a backup which didn't work either. I have attached a screenshot of the message.

Repeated clicking of the "OK" button on the message will eventually allow the vpn to open, but I'm not sure if it is working correctly.

Can this be fixed?

Hello Community and/or Support,

After installing the latest "Mozilla VPN Release 2.40.0" upon Windows 11 Version 26H2 OS Build 26300.9711, I received the follow error message 3 to 4 times in a row. after acknowledging the error (pressed "OK").

(See attached image) Mozilla VPN.exe - Bad Image is either not designed to run on Windows or It contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support. Error status OxcOOON28.

Prior to installation, I just booted my computer and observed that my VPN App needed to be updated. I did not open any other app or perform any other work.

The VPN update informed me that it needed to close my current VPN connection to continue with the installation Update, which I allowed the update to manage.

In my troubleshooting efforts, reviewing other forums, and ask Google Gemini, I have performed the following. 1). Rebooted the computer after install. (Same Error Message) 2). Uninstall and reinstall Mozilla VPN. (Same Error Message) 3). Updated my NVIDIA GeForce GTX 1660 Ti driver to the latest release. (Same Error Message) 4). Ran "sfc /scannow" as administrator within the Command Prompt (Same Error Message). 5). Ran "dissm /online /cleanup-image /restorehealth" (Same Error Message).

Is there a method to correct the "Bad Image" error from popping up after restarting my computer? Also, would someone be so kind to inform the Mozilla VPN software team of this error?

Thank you all for your time!

Hello, I have been trying to use Thunderbird for the past 3 days, but my attempts to set up an account fail every single time—even though my email address and password are correct.

What do you recommend I do? Thank you.

How can I prevent other sources from bypassing my Firefox/Mozilla downloads and installations? I once had a secure Firefox account. Now every time I update or reinstate there is a possibility that it will be violated in the future without my direction or approval? HELP

still have a old version of Firefox on my desktop

Tried to uninstall but got message: can't because helper.exe is not in appdata/local/uninstall

found a helper.exe and uninstall map, put it in Mozilla Firefox in local. Now I don't get the message that it can't be found but app is still not uninstalled from programm files.

If I tried to apply hlper.exe by hand, it doen not work.

How do I get rid of this version 135

I understand Thunderbolt AI is available. Can I use it as an ordinary Thundermail user to ash questions just like I would ask a question of ChatGPT etc? If so, how do I install (Windows 11, Android) and get started?

It is really sad that there is no way to contact mozilla directly The update installed on my Windows 7 64 bit is now storing cookies for Proton Mail and that makes the storage amt increase from 29Kb to 78Kb and I am not happy that I can not find a way to remove or revert the update so detail steps to complete that process would be nice. As for my future use of Firefox and involvement with Mozilla I am very seriously considering NO further use of both and your claims are starting to become lies you are permitting tracking in my view of this behavior Community Members should not be dealing with these concerns GET OFF your lazy back side Mozilla

I'm trying to use Firefox instead of Google but I'm very confused. Do I have to use Google Play store to get the apps I use. How do I switch all of my apps from Google to Firefox

This is a new install of debian 13 trixie. I have a subscription to mozillavpn. It was working on a previous install of debian. I use synaptic to install flatpak. I use flatpak to install warehouse. I use warehouse to install mozillavpn. Once installed I highlight the package mozilla vpn in warehouse then click open. A mozillavpn icon appears in the taskbar. Also a window that is shaped like a cell phone open up. This window has a button to "sign up", also it has a link to "already a subscriber?". I click the "already a subscriber" link. It changes to a page that says "waiting for sign in and subscription confirmation..." with a rotating circle and a button to cancel. It also opens a separate browser to a start page. I wait awhile but nothing happens. I change the browser page to my mozilla account page at "https://accounts.firefox.com/settings" Nothing happens. There's a button on the account page to "connect a device" but I don't know what to do with it. Under the heading "Everything you are using and signed into." it has 2 entries: "Firefox 153, Linux" and "Mozilla Support". Both entries have a "sign out" button. Back at the mozilla vpn cell phone shaped window the spinner just spins and nothing else. So I'm stuck. I click cancel and it goes back to the "sign up' / "already a subscriber?" page. From the icon in the taskbar I click quit and both the window and the icon go away. Everything seems to working but I am not registering as a subscriber. I've tried this several times over the course of 2 days. It's always the same.

Hi! I´m using Jdownloader2. After an update of Firefox the captcha-extension of JDownloader didn´t work anymore. I reinstalled Firefox, but adding the extension is still prevented. Following quote appears: "Firefox hat die Website daran gehindert, Sie zu fragen, ob Software installiert werden soll" It should be in yellow (but it isn´t), like following site describes: https://support.mozilla.org/de/kb/Add-ons-koennen-nicht-installiert-werden#w_firefox-hat-die-website-daran-gehindert-sie-zu-fragen-ob-software-installiert-werden-soll Furthermore there should be a button to authorize the installation. Instead there is only the button "OK". I followed the help-site mentioned above to the letter, to no avail. By the way, I´m using Nightly now, but JDownloader2 automatically wants access to Firefox. Would you please tell me, how to add the mentioned extension. Without it I couldn´t download most files! Please answer to following email: [redacted email from community support forum]

Hi,

In the latest firefox update 154, no start pages are displayed that were distributed with a registry key via group policy. It only works again if you change this setting manually in the Firefox settings.

In Version 153 it´s fine.

When the new update arrived yesterday, I started getting multiple popups from McAfee & Mozilla. Three stay on the screen at once, and when I X one, another appears instantly. This appears to be a scam trojan, but 3 different excellent anti-virus programs have not found anything. This never happened until the latest update. What do you know about this? I don't want to uninstall & start over, but what other suggestion do you have? p.s Usually when I right click on one of them, it takes me to a McAfee ad. I just clicked on one that gave me the option to turn off notifications. That seemed to stop it, at least for now. Am I the only one with this problem? [redacted email from community support forum]

Firefox created a folder "Old Firefox data" on my desktop which is impossible to delete. I am getting an error "Access denied" even when trying to delete it as administrator. How can I delete this folder?
