Hi Doug, to cancel the authentication dialog, try tapping the Esc key several times quickly to break the reload cycle. After that, you should be able to close the tab using Ctrl+w, or press Alt+Home to navigate to your home page. Does that work in this case?

A way out of a trap page is to (force it if needed) Close Firefox. Wait about 20 seconds for Firefox to finish closing. Right-click on the Firefox icon and select Open New Window. +++++++++++++++++++++++++++++++++ Sometimes this works. If it opens, close it by Menu > File > Exit. This will flush out that web page from the Session Store.

Hi - I'm unable to load Firefox because the home screen is hijacked. I've run the free Malwarebytes and it finds nothing. I've used CCleaner as well. I've loaded a print screen. Any help will be much appreciated. Doug

Hi to everyone who sent a solution. It seems that the first time I ran CCleaner and Malwarebytes, that nothing changed. I don't know what changed, but while the browser was up with the message "YOUR COMPUTER HAS BEEN BLOCKED" I ran CCleaner and Malwarebytes again and then used the Task Manager to kill Firefox. Then when I ran Firefox again, it ran without problem.

That was very good work. Well done. Please flag your last post as Solved Problem so others will know.
