General confession is something that came out of Russia (I believe it was Kronstadt), probably under Latin influence. It is not an Orthodox practice.
The Communion Prayer is recited (or should be recited) silently by those who are to receive the holy Mysteries only.
In some churches it is used as a General Confession, recited aloud, which is wrong.
not a supporter of general confession myself just noting that it seems the local oca folks are trying to reestablish confession in general.
I've never been in a rocor parish where they didn't ask prior to communion whether I'd gone to confession. it seems to me they're probably on par with the serbian churches in that regard.
also. the general confession I'm referring to was held saturdays after vespers... in the oca parishes ... definitly not a few lines inserted into liturgy... each person approached the priest one at a time...
Please elaborate on what you mean by "General confession".
I don't beleive what St John of Kronstadt practiced was general confession (nor do I see a disparity between what is prescribed in Holy Scripture and what St John practiced):
"Some of the pious were even led to believe that there was some relation between this innovative exercise called "General Confession," and the mass Confessions conducted by St. John of Kronstadt. NOTHING OF THE SORT! In the practice of mass Confessions conducted by St. John of Kronstadt, all, according to witnesses and participants, said or, in many cases, shouted aloud all their individual sins. That is, the Christians who participated in this mass Confession did not speak their sins ONLY in the presence of an ordained Priest in the relative seclusion of the Office of Confession, but in the presence and hearing of their friends and neighbors and strangers standing beside them in Church!"

ROCOR thoughts on confession before communion (very strict)

I have never seen such a thing, to the best of my knowledge.
