I'm connected through a public wifi hotspot. No problem when using IExplorer. When I use Firefox, I obtain the following error message after asking for any https url, as for example

An error occurred during a connection to

SSL received a record that exceeded the maximum permissible length.

(Error code: ssl_error_rx_record_too_long)

How can I solve?

check your proxy... – PersianGulf Oct 3 '13 at 16:36
This can occur because of a misconfiguration of AntiMalware software that includes "internet security" or because something in the chain is redirecting the https URL to http, and your browser does not like it. – Richie Frame Oct 5 '13 at 8:17
So, there is a proxy or AntiMalware that prevents Firefox from working but not IExplorer? Really? – Toc Oct 5 '13 at 9:44
The problem may not be due to a proxy or antimalware issue, but Firefox can be configured to use the system proxy settings, which is what Internet Explorer uses, or can be configured to use a manual proxy setting in which case even though Internet Explorer may not be routing your HTTP/HTTPS connectivity through a proxy, Firefox may be using a proxy. Also, with some antimalware products, you can configure the software for "safe surfing", which might be turned on for one browser, but not another. – moonpoint Jul 25 '15 at 2:15

This problem can be repair with uncheck the TLS encryption. Tools > Option > Encryption (tab) > and uncheck TLS 1.0.


Look for these preferences(security.tls.version*).

  • security.tls.version.min
  • security.tls.version.max

In the Awesomebar, type or paste about:config and tap the Go arrow. Type tls into the search box and tap the Enter key to find all preferences that contain tls.

According to a comment in the code:

// 0 means SSL 3.0, 1 means TLS 1.0, 2 means TLS 1.1, etc.

So try setting both min and max to 2, to force TLS 1.1, and see whether that works.

Sorry, tried with no luck. Same error as before. – Toc Oct 3 '13 at 16:39
@Toc updated my answer with a possible solution. – quark8 Oct 3 '13 at 17:11
Sorry, nothing even after your update. By the way, Firefox 24 does not have Encryption tab on Adavnced section in options window. – Toc Oct 4 '13 at 13:06
Furthermore, by the way, I have recognized that my IE is set to use TLS 1.0 and not 1.1. – Toc Oct 4 '13 at 13:09
