By the way, thank you for your colorful simile--it really spurred me to fix this issue this morning, and I've definitely learned to take cross-browser compatibility more seriously. Cheers.

Lamentable. Must be some missing cross-browser CSS.. I'll look into it tomorrow! In the meanwhile try it in Chrome if you have a chance :)

The particular generation algorithm that you see is called "Randomized Prim's algorithm" on Wikipedia. It starts at a random cell in a grid, marks it as discovered, and adds all of that cell's adjacent walls to a queue. It then selects a random wall from the queue and, if the cell on the other side of the wall has not yet been discovered, opens up that wall. It adds all of the adjacent cell's walls to the queue, marks the adjacent cell as discovered, and selects the next random wall in the queue until all the cells have been discovered. It's kind of a modified BFS. This algorithm guarantees that all cells are connected.

That's right, it does a breadth-first-search from the end-point immediately upon clicking the end-point; it then traces the path from the start-point, following the parent-pointers set during the BFS, painting the DOM in the process.
