Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I'm on 13.04, stock firefox.

Mouse freezes, ctrl+alt+terminal does not work.

It locks for about 5-10 seconds at a time, while loading a seemingly innocuous webpage.

It gets back to normal after the lockout.

I use ghostery and adblock.
