Today I did some grocery shopping on maxi.ca. The site is slow. Probably very badly optimized. That goes for all browsers. But on Chrome, it's a passable experience. I can type in the search field at a normal speed. I can generally scroll without too many issues. But on Firefox, it is excruciating. When I type in the search field, it takes a few seconds for each letter to show up. When I scroll, there's often a significant delay. When I add a product to my cart, the button takes a good full second to react. And it gets worse as you keep using the site. At some point 10-15 minutes in, it's no longer usable. You need to refresh the page or even kill Firefox to restore things to the horrible but usable initial experience. I don't know what's going on. Are they coding things horribly but Chrome has some kind of cheaty optimization to compensate for horrible JavaScript? I don't know but this is starting to erode my loyalty to Firefox, built on the fear of a web engine monopoly and moral principles.
