Why LiveJournal? Why?

So, there's this thing that happens when I'm commenting from my PC. I'll get about 3 or 4 words out, then WAM!, suddenly, even though I haven't clicked a thing, or so far as I know hit any key combinations, LiveJournal posts my comment. All 3 or 4 words in my unfinished sentence.

Now, I'm a pretty good typist. Not perfect, but learned how to touch type back when that was a pretty standard high school class. Also, I type faster than many people, but I'm still in a pretty normal range, somewhere between 40-60 wpm, I would guess, with pretty high accuracy. So, it doesn't seem like I'm doing anything that should cause strange behaviors in my browser (Firefox) or in LiveJournal.

I will note that this doesn't happen when I'm using my phone, either. But, of course, that's a completely different interface. Not only that, but my speed is pretty slow when I'm using a touch screen keyboard.

So, if you've noticed these strange, truncated messages from me, that's why. My apologies for any confusion this may have caused you.
