I have Firefox 63.0.1 64 bit using Win 7. After the latest update, I frequently get the "performing a tls handshake" when trying to view a webpage. After 7 to 8 minutes I get a message saying "Secure Connection Failed. The connection to the server was reset while the page was loading. 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." I've researched this problem and haven't come up up with an answer as to how to correct this. Does anyone know how to correct this?

Ever since I upgraded to Firefox 63, several trusted websites have stopped loading; instead I get sent to an error page with:

Your connection is not secure

The website tried to negotiate an inadequate level of security.

<www.thestar.com> uses security technology that is outdated and vulnerable to attack. An attacker could easily reveal information which you thought to be safe. The website administrator will need to fix the server first before you can visit the site.

Error code: NS_ERROR_NET_INADEQUATE_SECURITY


This also occurs with https://download-installer.cdn.mozilla.net/pub/firefox/releases/63.0.1/win32/en-US/Firefox%20Installer.exe

Is the problem at my end or theirs? If the former, what do I need to do to return to the behaviour for FF 62?

Just downloaded firefox for mac and get their own server as a security warning.....not very promising.

This Connection is Untrusted

You have asked Firefox to connect securely to www.mozilla.org, but we can't confirm that your connection is secure.

Normally, when you try to connect securely, sites will present trusted identification to prove that you are going to the right place. However, this site's identity can't be verified. What Should I Do?

If you usually connect to this site without problems, this error could mean that someone is trying to impersonate the site, and you shouldn't continue.

Since I updated to 77.0.1 firefox has for unknown reason has concluded that there is a system administrator which has disabled updates. It says so in setting (topleft) and in about firefox (instead of update button). I have been able to change all other settings that I know of. I have also refreshed the browser once, disabled all addons once, and deinstalled it to reinstall the latest version once.

Is there a solution for this bug?

Hi,

I've been using firefox for a while on this computer now, but this morning I was hit with a popup saying: "Windows cannot find 'C:\Program Files\Mozilla Firefox\firefox.exe'. Make sure you typed the name correctly, and then try again."

I have so far tried every fix I can find (which aren't many for this glitch), and none have worked. I have tried uninstalling and deleting all folders related to Firefox, and the new install still gives me the same error. My OS is Windows 10, and I have not had any problems with Firefox before this morning, nor have I made any changes to the files or anything of the sort. Just tried to run it and it gave me this.

I am at my wits end a bit with this. Help!

Windows cannot find C:\Program Files\Mozilla Firefox\firefox.exe I have tried all of the solutions I can find on this forum (downloading all of the free antimalware kits and scanning for malware and allowing my firewall to make an exception for FF) but these have not worked. Strangely I also cannot open any MS Office files either. Use Avast.

I clicked on 'Restore All Windows' but all I got was a bunch of new windows and on only one Window of about 8 that are now lost or gone. Months to build... now if I can't restore these, it will take weeks or a month or more to build back what I had!

when i tried to open firefox today, it said that it could not find c:/program files/mozilla firefox/firefox.exe. when i go to the file location it is there, but is listed as a .sig file? is that right? i have tried registry editor, uninstalling and reinstalling, etc. i have not done windows update 1909 because i did it before and things went all wonky so i went back to 1809. i don't know if that could have anything to do with it? is there a difference between just downloading firefox and i keep seeing "full version"...i am very confused. and fairly tech savvy. help, please. thank you.

Ever since a random point in the middle of the afternoon today, Windows 10 has become completely incapable of running firefox.exe. I have done a complete reinstall multiple times, wiping any and all traces of Mozilla from my system before running the installer again. I have run antivirus scans, and attempted to start Firefox with my antivirus (Avast!) completely disabled. I even tried starting firefox.exe from the command line, using tab completion to ensure that the file existed. No matter what I do, I get an error message from Windows claiming that it can't find firefox.exe, even when this is the result of double-clicking that exact file. This does not happen for any other software, including the portable version of Firefox (which is useless, since nothing is saved and I need my addons). I'm beginning to think that this is the result of either an absurd mistake or deliberate action from Microsoft, as there has been more than one Windows update within the day, and I have noticed other weird issues like my desktop background occasionally just being removed from existence for no reason.

Firefox 73.0.1

It is being used on a home desktop running Win 7 Home Premium.

In 'Tools->Options->General,' a blue link states 'Your Browser Is Being Managed By Your Organization.'

When I click on the link, a new tab opens with 'Enterprise Policies' stating:

'Policy Name': 'Certificates'

'Policy Value ': ImportEnterpriseRoots'

'Value': 'True'

Are they the settings that I want or am I missing something?
