I keep getting the error message:

Firefox could not install the file at

https://addons.mozilla.org/en-US/firefox/downloads/latest/1833/addon-1833-latest.xpi?src=addondetail

because: Unexpected installation error Review the Error Console log for more details. -203

I get this error when I try to install any add-ons. I have check the Error Console log and receive these messages/errors:

support.mozilla.com : server does not support RFC 5746, see CVE-2009-3555

Error: uncaught exception: [Exception... "'[JavaScript Error: "e.location.getItemLocation(e.id) is null" {file: "file:///C:/Program%20Files/Mozilla%20Firefox/components/nsExtensionManager.js" line: 3532}]' when calling method: [nsIExtensionManager::uninstallItem]" nsresult: "0x80570021 (NS_ERROR_XPC_JAVASCRIPT_ERROR_WITH_DETAILS)" location: "JS frame :: chrome://mozapps/content/extensions/extensions.js :: anonymous :: line 2929" data: yes]

I have unstalled and reinstalled firefox. I have checked to ensure that I have the most updated verison of Java. I have ran firefox in safemode, restarted my computer, even ran a virus scan. Nothing is working! I love the add-on yoono but it is one that will not install. What is this error? I am completely lost. Thanks for your help.

This fixed the problem. I had to do it several times so if the first couple times does not work, keep doing it and restarting your computer. I believe I deleted the extension files at least 10 times last night and this today only once. Last night, I only restarted firefox. Today, I restarted the computer and it worked perfectly.
