Firefox Support Forum

I've just done a Firefox Refresh which has been a bit of a disaster as any attempt to connect to any sites now gives a message to say that they don't have the right certificate and are insecure. The same goes for your own site!

Any help please??

I turned on Firefox this morning (after a Microsoft update/shut down last night). Heading to my usual pages where my logins/passwords come up automatically, I discovered the boxes were empty - they are usually filled by autofill; these are login pages to my blog, Amazon, eBay etc. I had also been logged out of my Firefox account, so I logged back in (I had remembered that password, luckily) Checking Options/security - show saved logins, I found absolutely no list of saved logins at all. (Horror!) I synced Firefox - still no list of saved logins Where have they gone and how do I get them back?

Hoping someone can help 'cos it's about five years' worth of saved logins.

I'm using the 32 bit version of Firefox on a 64 bit ASUS Windows 10 laptop and there is no Flash plug-in. I thought to try switching to the 64 bit version, but I get the above Network Protocol error message when trying to open the page https://download-installer.cdn.mozilla.net/pub/firefox/releases/65.0.1/win64/en-US/Firefox Setup 65.0.1.exe

Thanks

I just installed FF 63 on a 64-bit Windows 7 machine, and I'm getting SEC_ERROR_UNKNOWN_ISSUER errors at many, but not all, websites. Reaching the same websites via the same URLs using Chrome works fine.

All discussions of this problem seem to lead to https://support.mozilla.org/en-US/kb/error-codes-secure-websites?redirectlocale=en-US&redirectslug=troubleshoot-SEC_ERROR_UNKNOWN_ISSUER, but it's not helpful. My antivirus is Bitdefender Free, which appears to have no option for disabling the interception of secure connections.

Running FF in safe mode behaves the same as in "normal" mode: I get SEC_ERROR_UNKNOWN_ISSUER errors at many (but not all) websites.

Help? As things stand now, FF is pretty close to useless for me.

Ripeto i miei dati: windows 10 aggiornato; kaspersky internet security; tutto funziona perfettamente. Oggi ho aggiornato a Firefox 63. Da ieri mi appare che i segnalibri non possono funzionare correttamente. Ho seguito tutte le vostre possibili soluzioni ed aiuti. Da ultimo ho provato a ripristinare i segnalibri; mi dice che non posso salvare il backup. Cosa posso fare. Grazie. SOCREMBERGAMO

The last couple of months I have not been able to use my Outlook and send emails or save drafts. I have gone to outlook support but since it still works with Chrome and IE they say its firefox's issue and have no other help for me. I've cleared cache and history. extensions etc.. So I am coming to you now. I do have a VPN but outlook still won't work with it not on. So I am at a loss as to what to do. I don't like chrome nor IE and I've always had firefox and I want to continue that. I was still able to send emails when I first got the VPN so Im not sure what it is except very, very annoying. The same is for my laptop and that does not have the VPN.

How i can fix this issue? Thanks!

Hey Guys and Gals,

I have a website problem with Firefox in Windows 10 Home 64bit oem.

I am trying to get to Cyberlink.com and I get error . I also get error if I try using Chrome. Attached at 2 screenshots, 1 FF and 1 Chrome.

I cant access the site using either browser in wiindows 10.

Microsoft Edge accesses it fine thou. Also I have a Linux virtual OS on my system and I can access Cyberlink.com using firefox in it.

I thought maybe it was my system but it also happened on 2 other computer running Windows 7. But to be on safeside I ran Windows 10 troubleshooter and no problems were found. I ran SFC /scannow from Elevated CMD prompt and it found no errors. I than ran a DISM /Online /Cleanup-Image /CheckHealth and it found no problems.

Anyone else have an issue accessing Cyberlink.com (cyberlink dot com) just in case links are blocked?

And how would I fix the issue if it is only my system?

Please let me know. Thanks in advance Gren

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?

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?

I have been using Firefox for years to login to Garmin Connect with no problems, now all of a sudden the login window on the login page of Garmin Connect is not displaying. I have tried Microsoft Edge and the login window displays and I'm able to login.

I have tried to add screenshot images but they won't upload.

This morning Firefox was connecting to youtube.dom quite nicely. Then I accepted and installed the Firefox Update to 63.0.1 (64 bit) and ever since I cannot connect to youtube.com. I get an error page that says: Secure Connection Failed

The connection to www.youtube.com was interrupted 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 can connect quite nicely on Google Chrome (ugh!) but I want to continue with Firefox. Can this be fixed?

I try to get my passwords to fit into a cryptic system. Silly me. Firefox updated itself today and wanted me to enter my google password before doing anything. Since my Google password is a cookie, and Firefox is yet another cookie it became a labyrinthine task. Sorry!. Beyond that, Firefox would not accept a security question (the answer to which is precyberhistoristorical). That is my history, which is not much documented. I wish that we didn't need to lose everything as we go about the task of changing passwords all the time. I am about to turn 60, and I love firefox!

I've been using Firefox for a long time and I've kept it pretty vanilla. Today, I tried to logon to a website and it requires Recaptcha. When I opened the page, the recaptcha box didn't appear.

In regular mode, the Recaptcha box doesn't appear. When I use Firefox in safe mode, it shows and works properly.

I'm using Windows 10 and Firefox 63.0 (32-bit). I tried this in a private window with the same results, that Recaptcha doesn't appear.

Chrome and Edge works as expected. Firefox Android works perfectly.

The only add-ons I'm using are for downloading Youtube videos and converting/splitting them. Media Converter and Muxer, yD YouTube and Video and Audio Downloader.

Recently, if I want to log into websites that require passwords, every time I open Firefox, I have to go to Options > Privacy & Security and RECHECK the box for "Ask to save logins and passwords for websites," which is now unchecked every time I open Firefox. I can't find a way to have the box stay checked session-to-session. This is a recent development and, I suspect, is related to the "upgrade" to the latest version. Is there a fix?

Hi all, looking for some help on this one.

https://crash-stats.mozilla.com/report/index/7fdf825e-c0b4-4604-872b-8f5160180912 https://crash-stats.mozilla.com/report/index/d47a7909-5d39-4f4f-913a-7cf2c0180912

All users on the terminal server experience the crash, and the Mozilla Crash Reporter afterwards. Firefox crashes after about 1minute being open, regardless of website I can force a tab to crash by opening a site with video eg. youtube.com First occurred 10/9/18
