It would help to know what address that was.

Maybe you mistyped it.

Hi   !

Is the full message :

"The address wasn’t understood Firefox doesn’t know how to open this address, because one of the following protocols (javascript) isn’t associated with any program or is not allowed in this context. You might need to install other software to open this address."


If so, would you do this please : Type in the address bar   about:config  (press Enter) (promise to be careful, if asked) And type and look for the preference : network.protocol-handler.external.javascript and make sure that its value is set to   false   (= default)

Do you use a bookmark or are you starting with the main (home) page of this website?

If you use a bookmark then navigate to the web page starting with the main page or the sign in page in case there is a problem with this bookmark.

You can try these steps in case of issues with web pages:

You can reload web page(s) and bypass the cache to refresh possibly outdated or corrupted files.

  • hold down the Shift key and left-click the Reload button
  • press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
  • press "Command + Shift + R" (Mac)

Clear the cache and remove the cookies from websites that cause problems via the "3-bar" Firefox menu button (Options/Preferences).

"Clear the cache":

  • Options/Preferences -> Advanced -> Network -> Cached Web Content: "Clear Now"

"Remove the cookies" from websites that cause problems.

  • Options/Preferences -> Privacy -> "Use custom settings for history" -> Cookies: "Show Cookies"

Start Firefox in Safe Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration is causing the problem.

  • switch to the DEFAULT theme: "3-bar" menu button or Tools -> Add-ons -> Appearance
  • do NOT click the "Refresh Firefox" button on the Safe Mode start window
