I was trying to up-vote an answer, but every time I've pressed the arrow, an orange notification box appeared saying:
I've kept trying for like 5 times, then out of the blue, I'm logged out!
A couple of seconds later I'm logged in! Tried again, and voila! the up-vote goes through.
So, I'm wondering:
What happened here?
What does this message means?
I was logged out earlier, but my browser wasn't aware of it and this box did in fact appeared with a reason, perhaps because I couldn't vote?
This happened using Firefox 13.0.1 under Ubuntu 12.04.
