Issue: How to fix SSL_ERROR_RX_RECORD_TOO_LONG on Mozilla Firefox?

Hello there. I am using Mozilla Firefox as my primary browser, and recently I have been experiencing some issues with it. Every time I try to open “https” website I receive a ssl_error_rx_record_too_long error and the web page does not load. I have been using this browser since I can remember and it is my favorite one, can you please help me to fix this issue? Thanks in advance.

Solved Answer

According to statistics, Mozilla Firefox is used by 5.27% of internet users in May 2018. Although it might not seem like a lot, it is a five percent of a total of almost 3.6 billion internet[1] users which equals to 190 million people worldwide. Thus, issues with Mozilla Firefox are just as important as of any other browser. Therefore, we suggest you read through this article to find out how to fix SSL_ERROR_RX_RECORD_TOO_LONG error on Mozilla Firefox.

The SSL_ERROR_RX_RECORD_TOO_LONG error is quite common and can occur due to issues with SSL.[2] Many users reported that they see this message when they are trying to access websites using HTTPS[3] protocol. Firefox displays a Secure Connection Failed window and informs that the SSL certificate could not be verified.

SSL certificates are used to encrypt data which is hosted on the hosted server. As soon as there is a request to retrieve it, the SSL sends the encrypted data and then decrypts it for the user to view. This way, there is no way for hackers to intercept the information, and it dramatically reduces the chances of hacks.


However, when something goes wrong, and the encrypted data gets corrupted in some way, Mozilla Firefox cannot verify this information as secure anymore, and that's why it displays the SSL_ERROR_RX_RECORD_TOO_LONG error. In most cases, it is due to wrongly configured SSL certificate on the web server.

Occasionally, the issue can be caused by an anti-virus software installed on your machine. In such case, you should try disabling it and see if the problem is fixed. However, we do not recommend leaving your PC unprotected, as malicious software can be hidden anywhere on the internet. Therefore, we advise you to install Reimage and make sure that no malware is affecting the device.

Prevent websites, ISP, and other parties from tracking you

Private Internet Access is a VPN that can prevent your Internet Service Provider, the government, and third-parties from tracking your online and allow you to stay completely anonymous. The software provides dedicated servers for torrenting and streaming, ensuring optimal performance and not slowing you down. You can also bypass geo-restrictions and view such services as Netflix, BBC, Disney+, and other popular streaming services without limitations, regardless of where you are.

A VPN is also crucial when it comes to user privacy. Online trackers such as cookies can not only be used by social media platforms and other websites but also your Internet Service Provider and the government. Even if you apply the most secure settings via your web browser, you can still be tracked via apps that you are connected to the internet. Besides, privacy-focused browsers like Tor is are not an optimal choice due to diminished connection speed.

Therefore, to stay completely anonymous and prevent the ISP and the government from spying on you, you should employ Private Internet Access VPN. It will allow you to connect to the internet while being completely anonymous, prevent trackers, ads, as well as malicious content. Most importantly, you will prevent the illegal surveillance activities that NSA and other governmental institutions are performing behind your back.


Recover your lost files quickly

Unforeseen circumstances can happen at any time while using the computer: it can turn off due to a power cut, a Blue Screen of Death (BSoD) can occur, or random Windows updates can decide to reboot the machine when you went away for a few minutes. As a result, your schoolwork, important documents, and other data might be lost.

Additionally, you might also be attacked by malware that can corrupt your Windows or encrypt files with a robust encryption algorithm, and ask for a ransom in Bitcoin for the decryption tool. Cybercriminals might not deliver what they promised, however, so it is better to attempt alternative file recovery methods that could help you to retrieve at least some portion of the lost data.

Data recovery software is one of the options that could help you recover your files. Once you delete a file, it does not vanish into thin air – it remains on your system as long as no new data is written on top of it. Data Recovery Pro is recovery software that searchers for working copies of deleted files within your hard drive. By using the tool, you can prevent loss of valuable documents, school work, personal pictures, and other crucial files.
