Firefox Update Installation And Conflict Error

Asked By 40 points N/A Posted on -

I want you to check the attached image first and then read the rest of the message.

Ok now if you have checked the error image you might have understood that what my problem is.

Whenever I try to find updates for some add-ons on Firefox I get the updates but just after it shows the updates and I try to install those updates I receive this message that SSL received a record that exceeds allowed limit.

An error occurred during a connection to services. addons. Mozilla. Org:443.

SSL received a record that exceeded the maximum permissible length.

(Error code: ssl_error_rx_record_too_long)

Please tell me that if this error is due to a heavy update file which has a non-permissible size then I will not install that update and if it is not due to that then tell me why is it occurring.

I need to install updates as they are linked to my work.

So I am waiting for your reply regarding its solution.

Firefox Update Installation And Conflict Error

  • The error code : ssl_error_rx_record_too_long is not due to heavy update file like what you suspected, instead it means that the implementation of SSL on your server is flawed or installed improperly on your server, violating SSL specification.
  • To fix this, you should check port 443 which is the standard port for https communications. Port 443 should be enabled on your server and is running on secured connection. If you are using Apache2, you can check if you are using port 443 for SSl connection by setting the ports.conf file:


  • Listen 80
  • Listen 443


Make sure that all SSL certificate have its own dedicated IP, not sharing the same IP.

Firefox Update Installation And Conflict Error

  • Your problem is cause of incorrect implementation of SSL on the server. 
  • Try to do these things to solve the error;
  • Check the 443 that should be open and enable as a standard port for https communication. Having the code error is the result of Firefox that its SSL port is a non-standard one. Make sure the port 443 runs with your SSL.For using the Apache2 mark it for using port 443 for SSL. Also check your host config. for the changes and specially ensure the certificate of your SSL for the expiry date. This will help you solve the error.
