Glasp for Firefox

The humble act of highlighting is older than fire. Medieval monks scribbled in margins; Talmudic scholars layered commentary upon commentary across centuries. But Glasp does something stranger—it quantum-entangles your reading with the reading of strangers. When you drag your cursor across a passage, you're not just marking text; you're casting an observation that collapses the wavefunction of information into a new, shared state. The page is no longer a static artifact; it becomes a living superposition of every mind that has ever touched it. Think about the observer effect in quantum mechanics. A particle exists in a haze of possibilities until measured. A text exists the same way—a blur of potential meanings until someone highlights it. Glasp is the measurement apparatus for the mind. Every highlight is an act of creation, carving a path through the informational wilderness that others can follow. It's like leaving glow-in-the-dark footprints through a cave, except the cave is the accumulated knowledge of our species, and the footprints are beams of attention. And then there's the social dimension, which is where things get properly weird. In the many-worlds interpretation, every observation spawns a branching universe. Glasp creates a similar branching: each annotation is a fork in the road of understanding. When you see what strangers have highlighted, you're peering into their cognitive universe—seeing the cosmos through their eyes. It's a form of telepathy, really. You're not sharing facts; you're sharing *what
