You can try to disable forcing a secure connection in Facebook.

Clear the cache and cookies only from websites that cause problems.

"Clear the Cache":

  • Firefox/Tools > Options > Advanced > Network > Cached Web Content: "Clear Now"

"Remove Cookies" from sites causing problems:

  • Firefox/Tools > Options > Privacy > Cookies: "Show Cookies"

I followed the instructions and it worked last night and today I have the same problem. Is there a permanent solution and what causes this to happen, I am not accustomed to have problems when logging in with FF

That particular error — Error code: ssl_error_illegal_parameter_alert — seems rare on the forums. In one past thread, it was caused by the filtering program NetNanny. See: SSL error illegal handshake.

If no external software is a logical culprit, check these:

(1) Proxy

Try bypassing any proxy server/service by setting "No Proxy" here:

orange Firefox button (or Tools menu) > Options > Advanced > Network mini-tab > "Settings" button

(2) Extensions

Firefox's Safe Mode is a standard diagnostic tool to bypass interference by extensions (and some custom settings). More info: Troubleshoot Firefox issues using Safe Mode.

You can restart Firefox in Safe Mode using

Help > Restart with Add-ons Disabled

In the dialog, click "Start in Safe Mode" (not Reset)

Any difference?

Indeed rather a rare error code, but it also happens with a combination of Firefox 26.0 and Kaspersky Endpoint Security 8.1.0.831 (a.b.c.d) when "Web Control" is enabled. I had to stop Kaspersky "Web Control" to make this problem disappear!

Thank you for the advice, I do run Kaspersky and will disable it to see if this will work and report back so that if there is others that are experiencing the same problem can also bennefit from this advice

You're welcome, hope it helps you out. Just to be sure, of course I did not disable all of KAV, only the "Web Control" function. Good luck with your troubleshooting.

It happens for users not using kaspersky, too.

Unfortunately mozilla team is silent about this problem - https://bugzilla.mozilla.org/show_bug.cgi?id=951156
