Firefox-Hilfeforum

A couple users at our site intermittently receive a SSL_ERROR_BAD_MAC_ALERT error when navigating to Google in Firefox. This happens in Version 99.0.1 (64-bit) on Windows 10 computers. When the issue occurs, users can navigate to other websites without issues. Navigating to Google in a different browser works no problem. Restarting the browser will resolve the issue. Clearing cookies and site data has no effect. Users can also refresh the page after some time and the issue will go away.

Any idea as to why this is happening?

Firefox 99.0

I guess it's a problem with the latest update because it didn't happen to me before. Gmail keeps showing me this message: "Gmail is having authentication problems. Some features may not be operational. Please try logging in to troubleshoot the problem." I have relogin, deleted the cookies and site data but I still get that message. I have tried starting the browser from "about:support" in troubleshooting mode but the error still appears. This does not happen in other browsers.

I have been trying to get on the Malwarebytes website, but I keep getting;

Your connection is not secure

The owner of links.malwarebytes.com has configured their website improperly. To protect your information from being stolen, Firefox has not connected to this website.

links.malwarebytes.com uses an invalid security certificate. The certificate is only valid for the following names: *.fortinet.com, fortinet.com Error code: SSL_ERROR_BAD_CERT_DOMAIN

This happens with all of my web browsers. Is it safe to allow Fortinet ?

Hi all,

Since I switched to Win 10 Firefox constantly crash on my computer.

• Tried fresh install no change
• Tried repair no change
• Switched off extension and then on (one by one) no change
• Deleted cache - History - etc .. :( it worked for only a few days since I did a full scan with Microsoft Defender.
• Since this last crash (as I could not launch Firefox anymore I used shift + click on Mozilla shortcut)I decided to switch off the graphic card acceleration and all the other option in this menu and it seems to help

Could you tell me how to send you the crash report ( I do have 8-10 of them already sent to Mozilla)
