Prevent sluggish script performance using GreaseMonkey

When I go to a certain website, there is an external script that loads very slowly, causing the page to be almost unusable at times. While disabling the script helps a bit, it means losing out on some important functionality.

I'm wondering if there is a way to use greasemonkey to stop this script from running. I know NoScript is an option, but I want to see if I can make it work with a JS timeout instead.

I'm not entirely sure if Greasemonkey will be able to cancel the script, as it seems to only run scripts after the page has completely loaded. However, I thought I would ask just to be certain.

Answer №1

Could the script potentially be hosted on a separate domain that is not widely used by other resources?

In this case, one option to restrict access to the script is by modifying your computer's hosts file. You can find detailed instructions on how to do this at

Answer №2

It's quite likely not possible. Since Greasemonkey executes last, it's not feasible to remove the tag before it triggers, and I'm fairly certain that Javascript cannot interrupt an HTTP request.

However, have you attempted simply deleting the script tag before it fully loads? This might work in certain browsers, as Greasemonkey scripts typically run on DOMReady rather than onload.
