I can't download or update firefox
I've tried updating firefox from firefox, and I've tried downloading the latest version in Chrome, IE, and Firefox. In all cases, when I click on the Download link, I get to a page that says something like the following. Can you help me get the latest version?
Secure Connection Failed
An error occurred during a connection to download.mozilla.org. The server uses key pinning (HPKP) but no trusted certificate chain could be constructed that matches the pinset. Key pinning violations cannot be overridden. Error code: MOZILLA_PKIX_ERROR_KEY_PINNING_FAILURE
The page you are trying to view cannot be shown because the authenticity of the received data could not be verified. Please contact the website owners to inform them of this problem.

Thanks for checking that. A Yahoo thing in Google's folders definitely doesn't sound related.
This issue could be "upstream" of Windows, in your router. If you have a cable router or DSL router from your service provider, you could try power cycling it (i.e., turn it off, wait 10 seconds, turn it back on) in case there is a transient issue in its ability to connect download.mozilla.org to the correct address.

Did you try this instead?
Yes, and I got the same result, even after clearing all history in both Chrome and FF. Do you have any other thoughts?
In Chrome, when I click on Advanced after getting that message, it tells me "This server could not prove that it is download.mozilla.org; its security certificate is from www.popscholar.com. This may be caused by a misconfiguration or an attacker intercepting your connection.
On another computer on my home network, it tells me its security certificate is from *.staging.adgoji.com. This may be caused by a misconfiguration or an attacker intercepting your connection."
Hi tomgoodell, those are good clues, and worrying ones.
Can you think of any reason that your browsers might be connecting to sites indirectly such as filtering software, a VPN, etc.?
Are other sites affected?
When I try the link for Windows 64-bit U.S. English Firefox 61, this happens:
Initial request:
https://download.mozilla.org/?product=firefox-latest-ssl&os=win64&lang=en-US
Server redirects to:
Is that second address blocked for you?
Or is this server blocked for you?
http://archive.mozilla.org/pub/firefox/releases/61.0/win64/en-US/
Regarding connection issues, Firefox settings might not be relevant, but just in case, you can check that here:
- Windows: "3-bar" menu button (or Tools menu) > Options
- Mac: "3-bar" menu button (or Firefox menu) > Preferences
- Linux: "3-bar" menu button (or Edit menu) > Preferences
- Any system: type or paste about:preferences into the address bar and press Enter/Return to load it
In the search box at the top of the page, type proxy and Firefox should filter to the "Settings" button, which you can click.
The default of "Use system proxy settings" piggybacks on your Windows/IE "LAN" setting. "Auto-detect" can lead to a flaky connection. You may want to try "No proxy".
Any difference?
You may want to supplement your regular security software with some other highly regarded "on demand" cleaners: Troubleshoot Firefox issues caused by malware.
Hi jscher2000,
I do have VPN software (NordVPN) installed, but have not used it in a few weeks and have rebooted my computer several times since then, including last night. Other sites do not seem to be affected. If, e.g., I got to Brave Browser and download that browser, it comes down fine.
I switched the proxy setting to "No proxy." but that made no difference.
The second two links you provided both work. Do you think it's safe to download following those links?
The second and third links are official Mozilla servers.
Could you check your Windows hosts file to see whether you have an entry in there for download.mozilla.org.
If so, please remove it.

There is nothing but comments in that file, it's just the generic sample file provided with Windows.
You may have a virus on your computer. I'd suggest running a free malwarebytes scan (www.malwarebytes.com).
Do you have anything developed by "popscholar" on your computer?
I don't have anything from poscholar, don't believe I ever went to their site. I'll run malwarebytes and let you know what I find.
OK, I ran Malwarebytes. It found two things it identified as "potential threats." They are documented as:
File: 2 PUP.Optional.WinYahoo, C:\USERS\TOMGO\APPDATA\LOCAL\GOOGLE\CHROME\USER DATA\Default\Sync Data\SyncData.sqlite3, No Action By User, [245], [454790],1.0.5671
PUP.Optional.WinYahoo, C:\USERS\TOMGO\APPDATA\LOCAL\GOOGLE\CHROME\USER DATA\Default\Secure Preferences, No Action By User, [245], [454790],1.0.5671
I quarantined them, but they had no effect on the problem. Any other thoughts?

That did it! I have a fiber optic modem and an Asus ethernet/wifi router. I rebooted the router and it didn't help, I rebooted the modem and it didn't help, but I found that I could then download FF on another computer on the network. So I rebooted my PC and it updated fine. Thanks to all for the help, happy to be up to date with FF!
