Hello Vicky.

It's possible that you are having a problem with some Firefox add-on that is hindering your Firefox's normal behavior. Have you tried disabling all add-ons (just to check), to see if Firefox goes back to normal?

Whenever you have a problem with Firefox, whatever it is, you should make sure it's not caused by one (or more than one) of your installed add-ons, be it an extension, a theme or a plugin. To do that easily and cleanly, run Firefox in safe mode (don't forget to select Disable all add-ons when you start safe mode). If the problem disappears, you know it's from an add-on. Disable them all in normal mode, and enable them one at a time until you find the source of the problem. See this article for information about troubleshooting extensions and themes and this one for plugins.

If you need support for one of your add-ons, you'll have to contact its author.

If the problem is not disappears when all add-ons are disabled, please tell me, so we can work from there.

Disabling addons will not prevent you from logging into Gmail.

You can enable add-ons next time you start Firefox.

I just solved this after reading http://support.mozilla.com/en-US/kb/Firefox+cannot+connect+securely+because+the+SSL+protocol+is+disabled

Go to Tools, Options, Advanced, Encryption and make sure that use SSL and use TLS are BOTH checked.

In my instance, TLS was not checked, and after checking it, I could then get back in to all the sites - such as GMail - that I'd been unable to get to before.

Unable to connect




         Firefox can't establish a connection to the server at sl-si.facebook.com.
       



 The site could be temporarily unavailable or too busy. Try again in a few
   moments.
 If you are unable to load any pages, check your computer's network
   connection.
 If your computer or network is protected by a firewall or proxy, make sure
   that Firefox is permitted to access the Web.
