This status bar tells us what Firefox is exactly doing to load a page. However, there can be times when Firefox gets stuck in a very specific step. It is the process of a browse to make an HTTP connection. Usually, this step only a fraction of second, but sometimes it can crash. If you see that your Firefox is getting stuck on this step for more than 5 seconds, then you have to know that you are facing the TLS handshake problem.

For that, you can take help of the following solutions When you encounter this problem, the first thing that you should do is make a new profile for Firefox.

If you see that these sites are opening without any problem, then the TLS Handshake Firefox has been fixed. This is one of the most useful processes for solving the Firefox TLS handshake problem.

When Firefox faces a problem with the splitting of the SSL certificates, at that time, the sites using the self-signed certificates get affected. This problem does not affect sites like Amazon. It affects private services and site users and developers.

A slow performing TLS handshake firefox is caused due to the cause of multiple time replacing with new certificates on sites with self-signed certificates. The number of possible path-building combinations eventually chokes Firefox.

And, every time you visit this site, you have to agree to these certificates. All these certificates are stored by Firefox. Whenever you will agree to these certificates, Firefox will look for a valid path.

This will help you to confirm that this is the cause of the problem. Temporary network issues can also result in occurring of this problem. If you see that all the connections of the HTTP are taking time to load, there is a chance that the problem is occurring due to the connectivity issues of the ISP. If this problem is occurring for some sites, then the problem may be due to the checking of the revocation.

This part of the TLS handshake requires third-party servers connection.Here's the FF result.

Here are a few ways to troubleshoot the issue:. The first thing to try is creating a new Firefox profile. When you use Firefox, all your personalized settings are connected to a specific profile. Your profile data could include misconfigured options or errant data that cause uncommon and hard-to-track-down bugs.

First, open a new tab and paste about:profiles into the address bar and hit enter. This will open the Profile Manager. You can try to troubleshoot your original profile remember to switch back to it using the Profile Managerhowever isolating the issue will be difficult check if you have a proxy connection configured, and try disabling your add-ons and it may be due to corrupted data in the profile, which cannot be easily repaired. Instead, you may want to transfer your important data to the new profile you created.

There is also a small chance the cause is related to self-signed certificates. If this issue is affecting sites using self-signed certificates, then you may be encountering a problem with the way Firefox parses SSL certificates. Note that if you are experiencing this issue on everyday sites such as Google. After doing this a number of times, Firefox will have stored all these certificates in its local database and check them all against these other in an attempt to see if there is a valid path.

Following the steps above to create a new profile will resolve this issue temporarily. An easy way to do this is to browse to about:support and then click the Open Folder button for the Profile Folder. Locate cert8. Restart the browser and try visiting an affected site again. If the page loads normally, you have confirmed the issue is related to the local certificate database storing too many self-signed certificates with the same name. Firefox starts to noticeably slow down after storing identically named self-signed certificates.

If it takes a while for you to accumulate this number of identical certificates, it may be workable to just repeat this process every few months. Otherwise, you will want to adjust the way your service generates new certificates so that they do not have identical information.

If you suddenly started experiencing this problem, it may be related to temporary network issues.During an HTTPS connection, the communication is actually done with symmetric session keys — generally bit AES keys — that are generated client side.

When a symmetric key is generated, both parties get a copy and can use it to both encrypt and decrypt. While bit encryption is still sufficiently robustthe real security is at the gate where a much larger, much stronger private key generally a bit RSA key helps handle the authentication portion of the connection. Historically, the handshake has added a small bit of latency to a connection, which is what led to the claim that HTTPS slows down your website.

Currently, there are two different versions of the TLS handshake in use. TLS 1. First and foremost, everyone needs to… shake hands?! Read more. And a lot of them may seem pretty trivial, things like making sure your system time is correct and your browser is updated. But, as we discussed, there are a lot of moving parts with the TLS handshake and sometimes even the tiniest hiccup can cause the whole thing to go kaput. In fact, in some rather high profile cases of certificate expiration — like with the Oculus Rift VR system — internet users have even purposely set their system times back to a date before said expiration so that they could still connect.

Sometimes your browser can become misconfigured, or a plugin can cause things to work a little bit differently and it results in problems connecting to otherwise legitimate websites.

While diagnosing exactly what needs to be tweaked on your current browser may be a little bit more difficult, narrowing it down to a literal browser error is pretty simple: just try another browser. Just switch it up and try connecting to the site. But if you can connect, now you know something is up with your plugins or settings.

The fastest way to fix this is just to reset your browser to the default settings and disable all your plugins. From there you can configure the browser however you want, testing your connection with the site in question as you tweak things.

A lot of programs and devices intercept traffic for inspection or some other purpose like load balancingand then send it along to the application server. This constitutes a MITM, too. Unfortunately, sometimes issues with those devices can cause a TLS handshake to fail. It could be something like a network firewall preventing the connection, or it could be a configuration on an edge device on the server-side network — so this issue can actually be either a client- or server-side fix depending on the scenario.

There should generally be a way to whitelist or create an exception for the site in question. Recently, Ross Thomaswas telling me about a device he dealt with once that was intercepting traffic and affixing a small data string to indicate it had passed inspection.

That was causing the data to fail check-sum hashes and could also potentially mess with authentication. Again, there are too many possible origins for me to narrow it down to a single fix here, but if you have a device inspecting or intercepting traffic, start there.

Some of these are easy to fix, some of them are a little more involved and some might not be worth fixing at all.

When it comes to supporting protocols and ciphers, the most important piece of wisdom is: always move forward, never move backwards. Earlier this summer TLS 1. Sites are being advised to add support for TLS 1. In this example, the client should upgrade their browser, or in the case that the browser is current — configure it to support the latest TLS versions.

At this point, you should be using TLS 1.When you are trying to connect for security purposes, it is an exchange of information process between the browser and the website. However, solving this issue is not that difficult. If you are here for how to fix TLS handshake Firefoxthen you are in the right place. Here, you can follow some easy steps on how to fix this error.

Given below are some of the possible reasons behind this. As now you know about the causes, you would be probably looking out for solutions. Just go through the following solutions to resolve it at the earliest.
