Firefox distrust Gmail and Facebook

[Goose]

For some reason Firefox has decided not to let me on to Facebook or gmail saying that they are untrusted. I told it view Facebook anyway but it just loads up all garbled an unviewable.

Is there likely to be a reason for this or is a reinstall necessary?

Isn't happening to me - are you sure you aren't being redirected to a fake site?

Using the same bookmarks i always have.

[Edit] This is weird, i'm getting the same thing with Chrome as well.

Is your clock telling the correct time/date?

Turns out it was this

For some reason after removing my motherboard to fit a new cooler it decided to reset my bios settings, including time and date.
