Youtube hijacked?

[gordon_s1942]

I just tried to access Youtube to deafen the neighbours (if I had any) by playing my high class selection of Music such as AC/DC, Hank Marvin, comedy and parodies and Firefox refused to let me open the site.
It kept telling me the site was 'unsecure' and the whatever it is was unverified etc.
The only way I could get Youtube to open was bypassing the security and making it an 'Exception' !

I have been using Youtube for a few hours over the last few day without problems so what made Firefox to spit the dummy today ?

The file cert8.db in your profile folder may have become corrupted. Delete this file while Firefox is closed.

Open your profile folder:

At the top of the Firefox window, click on the Firefox button, go over to the Help menu and select Troubleshooting Information. The Troubleshooting Information tab will open.
Under the Application Basics section, click on Show Folder. A window with your profile files will open.
Note: If you are unable to open or use Firefox, follow the instructions in Finding your profile without opening Firefox.

At the top of the Firefox window, click on the Firefox button and then select Exit
Click on the file named cert8.db.
Press Delete.
Restart Firefox.
cert8.db will be recreated when you restart Firefox. This is normal.

That is quite new to hear such a big site has been hacked. Well I am not experiencing any problems so far.
