Firefox keeps telling me: This Connection is Untrusted when it is ok to use
I am having problems when using certain websites such as Youtube for an example, prior to the start of this week everything has been fine but when I try and connect it is telling me theat it is Untrusted.
Also on many more websites to, and I have never had this problem before.

-> Update Firefox to the latest version 10.0.1
Perform the suggestions mentioned in the following articles:
- Clear Cookies & Cache
- Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems
Check and tell if its working.
Check the date and time in the clock on your computer: (double) click the clock icon on the Windows Taskbar.
Rename the file cert8.db to cert8.db.old in the Firefox Profile Folder to remove all intermediate certificates that Firefox has stored by visiting secure websites.
If that helped to solve the problem then you can remove the renamed file cert8.db.old unless you have user certificates that you may want to export first and import them in the new file.
Otherwise you can restore the certificates by renaming (copying) the file back to cert8.db
Firefox will automatically store new intermediate certificates when you visit websites that send them.
