I fail to see how a browser would limit the number of anything you would want to import into it. In theory, if the HTML of a given URL contained several million entries of any particular type (i.e., "Questions"), your browser would load them sequentially as needed. There IS NO LIMIT to the size of a page a browser can load. That's the beauty of the internet and the HTML language that supports it. If there are any limits they must be imposed by Canvas, and there should be an integer that expresses the answer to the OP's question. I have the same question, but for a completely different reason. I'm planning on dealing with item banks exceeding 2000 questions. Given that 2000 exceeds 100s and IS in the THOUSANDS range, your answer does not help me. Unless you can explain how the capacity of a browser may limit the number of questions stored in an item bank, presumably on an instructure server, you have not adequately answered the question. Since you are looking at this from the viewpoint of a reality that doesn't exist, could you please explain what you mean,if Firefox (Windows) is the browser? Using Firefox, I routinely access data sets that have millions of entries, does that mean I can access millions of items in a Canvas Item Bank, or is there a limit to the number of items that the Bank will hold (which is the OP's actual question, I believe)?
Thinking it over from my question point of view (which shouldn't be limited by the capacity of a browser because it really doesn't involve loading anything into the browser), what is the limit of the number of items that can be stored in a Canvas Item Bank? (again this should be an integer, or a maximum character limit, and whatever it is, it should be finite!)
