How to Fix Firefox’s ‘SSL_Error_Bad_Mac_Alert’ Error?

We can see the error “SSL Error Bad Mac Alert” in this section.

Using Mozilla Firefox, users may get the’ssl error bad mac alert’ error when attempting to access specified encrypted websites. If you send emails to Gmail via IMAP, you may experience this problem.

Following our investigation, we discovered that this problem occurs when an SSL check fails, leading the browser to display an error and prohibiting users from accessing the site. It is possible to rapidly resolve the problem in this circumstance by adding the website to the list of Insecure FallBack Hosts in the advanced Firefox Preferences menu.

This browser behaviour could also be caused by a network connection that is preventing communications between your browser and external servers from taking place. This problem can be resolved by simply restarting your network connection.

For example, an incorrect system-wide time and date could cause your browser to invalidate SSL certificates, resulting in the appearance of this warning. The problem was successfully handled for several folks who were experiencing the same problem by just altering the Date and Time settings.

Previously unknown to me, older computer configurations require a specific Firefox advanced setting to be enabled in order to connect to SSL3 web servers without experiencing any problems. On the Advanced Preferences tab, you can change the value of security to a higher or lower level of protection. ssl3

1. Adding Website to Insecure FallBack Hosts list

In order to prevent the SSL Error Bad Mac Alert issue from appearing again, you need go into your Mozilla Firefox configuration settings and add the secure SSL website to the list of Insecure FallBack Hosts.

The ability to circumvent the SSL check that was causing issues previously is provided by this feature. Many people who were suffering from the problem were cured as a result of the operation.

If you want to add a website to Firefox’s list of Insecure FallBack Hosts, please follow the methods outlined in the following section.

Using Mozilla Firefox, open the browser and type the words “about:config” into the navigation bar to access the Advanced Preferences menu.
Then, when requested, select Accept the Risk and Continue to the next step.
In the Advanced Preferences menu, type security.tls.insecure fallback hosts and press Enter to confirm your selection.
Then select the security.tls.insecure fallback hosts entry and make the necessary changes (right-hand section).
Enter the URL of the website that is causing you problems into the newly appeared text field and press the Enter key.
Check to see whether the problem is addressed by restarting Mozilla Firefox.
Let’s say you’re still receiving the security benefits.
Continue reading about the insecure fallback host’s mistake if you don’t want to risk compromising the security of your system, or move on to the next section.

2. Restart the Router/Modem

This problem, on the other hand, can be caused by a discrepancy in the network. It’s possible that your network’s status is in limbo, and that a firewall is preventing your computer from talking with remote web servers.

If this is the case, restarting your router should be sufficient to resolve the problem. NOT TO BE CONFUSED WITH RESETTING YOUR NETWORK ACCESS POINT. In contrast to a password reset, this does not change your existing credentials.

After then, you must wait 30 seconds before hitting the ON/OFF button once more. To ensure a successful operation, make sure the power wire is disconnected from the power outlet. It is possible that your network will be reset if your router/modem reboots.

If this is the case, proceed to the next probable option listed below.

3. Correcting Time & Date

Another possibility for your Mozilla Firefox to lose security is if an update is installed incorrectly.

Inconsistency between the date and the time compromises security.

The error tls.insecure fallback hosts is displayed. As a result, your browser may be forced to terminate the connection since the security certificate has been compromised.

If this is the case, you can remedy the problem by changing the date and time settings on your computer or mobile device. The repair appeared to be effective for other people who were experiencing the same problem.

To open the Run dialogue box, press the Windows key + R at the same time. To display the date and time windows, press the Enter key.
Upon entering the Date & Time box, click on the Date and Time tab and then select the option “Change date and time” from the drop-down menu.
To set the dates and times you desire, make use of the calendar that is provided in the Date and Time window.
Check to check if the problem has been resolved by restarting your computer and visiting the same website once more.

4. Setting Security.SSL3 to TRUE

SSL3 should be set to TRUE.
With real SSL web servers, it is possible to receive the’sl error bad mac alert’ problem message until you reach the Advanced Preferences and select Security in Firefox’s Advanced Preferences menu.

This is due to security concerns.

Strictly speaking, SSL3 is not enabled by default.

Firefox’s Security.SSL3 can be activated by following the instructions below.

Access the Advanced Preferences menu by typing about:config into the address bar of your Firefox web browser.
When prompted to “Proceed with Caution,” select “Accept Risk” and then “Continue.”
In the top search bar of the Advanced Preferences menu, type “security” to find what you’re looking for.
Input the results of the security check.
Simply scroll down the screen until you reach security and click on it.
You have the option of using a string, a boolean, or a float.
After then, look at the security value.
Save your changes and restart Firefox to apply them.
Check the same website that was experiencing the’ssl error bad mac alert’ error to see if the problem has been resolved.
