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 uses security technology that is outdated and vulnerable to attack.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.

I am asking this as a last attempt before giving uo on Firefox completely.

I cannot access the "Player" Page of the UK National Lottery Web Site if using Firefox. This is the page : https://www.national-lottery.co.uk/player/p/home.ftl

I get this error message : "SECURE CONNECTION FAILED. An error occurred during a connection to www.national-lottery.co.uk. PR_CONNECT_RESET_ERROR"

Windows 8.1, running Firefox 75.0, with Avast 20.2.2041 Anti Virus.

This used to work fine, the was saved as a Bookmark. I can open the Web Page fromthe same computer if I use google Chrome Browser, without any other intervention.

After extensively researching various Help Topics on Firefox here's what I've tried :

Turning OFF Avast Anti-Virus protection - makes no differece. Clearing Firefox History, Cache, and Cookies - makes no difference. Refreshing Firefox - makes no difference.

The other thing I have noticed is that the Home Page of the National Lottery Web Site - https://www.national-lottery.co.uk/ WILL load, but only as a page Text with lots of Links.

Any ideas ?

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!

Avast wanted to removed an Addon it didn't like so I allowed it to get rid of it. But Avast Destroyed My Previous Session! How Do I Get it Back? 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!

Hello,


I apologize in advance for my low level in English, I am a French internet user who has encountered a problem since this morning. I have Mozilla Firefox on Windows 10. So far, it has worked perfectly. However, I could see today, by turning on my computer that I could no longer access Mozilla Firefox. Indeed, when I click on it, I encounter this error message:

Windows did not find c: \ program files \ mozilla firefox \ firefox.exe. verify that you entered the correct name and try again


I do not understand why I have this message. When I go to C: \ Program files \ mozilla firefox I do have a "firefox" icon (exe application). but I clicked on it and it doesn't work. I would like to inform that by using avast, avast updated me mozilla firefox ... I repeatedly uninstall and reinstall mozilla firefox; I even turned off, turn on, and turn on the computer several times but nothing to do, it does not work.

Can you help me see more clearly please?

Thanks in advance.
