You are saying that you cannot see this page? see screenshot Have you tried Firefox in Safe Mode? https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode#w_how-to-start-firefox-in-4troubleshoot-modesf5safe-modesf

It does not happen in Safe Mode.

Sounds like an add-on is causing the issue. This is why a full browser screenshot would be helpful so that we can see what you're running. Try to re-enable your add-ons 1 by 1 to see which one is causing the issue.

Ok got it back,, I did what you said and it work.

Much appreciated.

Best Regards

Glad to hear, but what caused the issues? This will help other users with the same issue.

And mark it as resolved.

When I turned Ghostery off Twitter displayed normally. Thanks!

You just have to tweak Ghostery and it should work with Twitter. I'm a long time user of Ghostery and it's a must have for me.
