All three of these are to be considered the same sentence with the same meaning and all acceptable ways of writing it down.
Jack said "I hate Firefox, Chrome is better."
Jack said "I hate Firefox, Chrome is better".
Jack said "I hate Firefox, Chrome is better.".
All are correct and there is no solid answer to this,
The first is the only one I've ever seen used in correct English.
First one. And technically a comma after 'said' as others have mentioned.
First one. And technically a comma after 'said' as others have mentioned.
Full stop or a colon after said, bearing in mind it is a full sentence.
Mark said "I once helped my uncle, Jack, off a horse." <-- Correct.
Mark said "I once helped my uncle Jack off a horse".

lol, there's one way of reading that which is so wrong.
Following a form of to say, however, you'll almost always need a comma:
My father always said, "Be careful what you wish for."
If the quoted speech follows an independent clause yet could be part of the same sentence, use a colon to set off the quoted language:
My mother's favorite quote was from Shakespeare: "This above all, to thine own self be true."
When an attribution of speech comes in the middle of quoted language, set it apart as you would any parenthetical element:
"I don't care," she said, "what you think about it."
Be careful, though, to begin a new sentence after the attribution if sense calls for it:
"I don't care," she said. "What do you think?"
Convention normally insists that a new paragraph begins with each change of speaker:
"I don't care what you think anymore," she said, jauntily tossing back her hair and looking askance at Edward.
"What do you mean?" he replied.
"What do you mean, 'What do I mean?'" Alberta sniffed. She was becoming impatient and wished that she were elsewhere.
"You know darn well what I mean!" Edward huffed.
"Have it your way," Alberta added, "if that's how you feel."
lol, it's almost as if that's the entire point
Jack said, "I hate Firefox; Chrome is better."
Comma after "said". Terminating period before double quotes. Semicolon after "Firefox".
So potentially a very innocent statement could have a completely different meaning depending on where you put the commas.
British English.
Mark said, "Why has my horse worn a huge grin for the last two days?". Uncle Jack averted his eyes.....
