Will creating 2 vents solve loft moisture problem?

When it's very cold, moisture drips from the felt under the tiles of the roof. It could be up to 50 years old (70's house) so it will not be breathable. No issues whatsoever during the heaviest rainfall.

Currently, there does not seem to be any source of fresh air (no eaves providing this) so if I had a 100mm or 150mm circular air vent created on the far left and another on the far right of the breeze block wall shown in the photo, would that solve the problem?

Also interested if installing an extractor fan could be a solution?

An extract fan, or any improvement in air flow will help. Is this a detached, semi, terraced or what?

The light coloured stuff hanging down below the tiles, is that what you are calling felt?

Homes are warmer now, much more sealed, warm air retains more moisture, so it condenses out on cooler parts, such as the inner surface of your roof.

It would doubtless reduce it, if for some reason you are not able to improve eaves ventilation.
