Browser Block 

You have an open browser and plenty of time to browse whatever your heart desires, but there is nothing you can think of that you want to search.

I had a caramel macchiato at my side and the world at my fingertips, but nothing came. I realized that browser block had set in as I stared at my blank display.

browser's block 

Browser's Block is a temporary inability to begin a new keyword search on one of the popular web engines (Google, Yahoo, etc.) due to a sudden "blanking out" while staring at the screen. It's cause is unknown. AKA, "Google Block" or "Surfer's Block"

It's 2:12 AM, you are awake and seated at your computer. You want to look up something or learn something new, but your mind is so overwhelmed by the infinite keyword search possibilities that you are forced into a temporary paralysis called Browser's Block.
