Cold fronts can play a part in heavy rain here as well, by stalling subtropical depressions/tropical cyclones -the same as happens in the US. I wouldn't call that a cold front bringing extreme rain though. High pressure that stalls rain bearing systems doesn't mean high pressure causes rain.
The first link I gave was precipitation from a stalled cold front, it wasn't from a tropical cyclone. Here's another article:
And in any case, tropical cyclones aren't frontal, so they're a counterexample to "extreme rain events come from warm fronts"
The link is going to take time to open, but I looked up Nor'easters on wiki. I get the impression that the heavy rain comes from the warm air/sea temps encountered on the downward sweep of the system, which is still considered a warm front.
The Nor'easter is only the overall driver of the system, but that doesn't make all weather coming from that, a cold front event.

My link isn't about Noreasters, it was a cold front.

Source? Never heard of that before. Just because there's warmer air on one side doesn't make it a warm front. In any case, take a look at the animation from weather bug of a Northeaster:
Yes the Malta Weather service are already predicting even more & quite violent thunderstorms this autumn, just as we got last time sea temperatures were this high
Yeah, good old 2012 when in October and November it rained so much it caused extensive floods over much of the Tyrrhenian side of Italy

A front is only the line that marks different air masses and a cyclonic system can be from a cold source, while at the same time, having warm fronts embedded in it's leading edge
What if it increases temperatures and dew points as well?
Well, then it would be a warm front. Honestly, I was a bit confused what you were trying to say earlier. Non-tropical low pressure systems often have warmer moist air feeding in, that doesn't make it a warm front. Extratropical cyclones have both a warm and cold front. On the fourth page of this pdf, the precipitation follows the cold front part:
In any case, my main point was that warm fronts aren't the sole cause of extreme rainfall. In my experience, cold fronts tend to produce more intense though often shorter lasting rainfall than warm fronts. But there's plenty of variation.
Hopefully we wont get anything quite as destructive as that...
It started a bit later here, maybe because the water was a bit colder off the coast of Italy, but the last two weeks of October and the first one of November alone probably had more thunderstorms than i had seen in the first 9 months of the year
