Ah, well that's probably what's going on then. Every program (or in this case page) you open uses memory, and since you don't have that add-on, you're probably running out, so it's slowing things to a crawl.
I compare this sort of thing to a kitchen. The chef is the processor (or more than one cook in the instance of a multi-core processor), your counter space is memory, and your hard drive is the panty. The cook can only "work" on as many things as there is counter-space. Run out of counter-space? No problem, move stuff to the pantry temporarily. But that back and forth is wasted time, and it slows the works down.
I'm still going to try again later with an alternate browser. Probably Microsoft IE, to avoid downloading Chrome just yet.
...In the meantime, considering your analogy example, do you you think it would be fruitful to install more "counter space"?
Possibly. It certainly wouldn't hurt, and RAM for something like that wouldn't be terribly expensive. However, as much as I like IE (and I do appreciate it), these days it doesn't run as fast as.. well, pretty much anything else.
