Remove noscript how to#

Providing a noscript-fallback for conditional functionality that is determined on the client might be a bit niche but shouldn’t be that uncommon either. Often we still want to provide a default variant (in a noscript-tag) for people without JS, or as graceful degradation in cases where JS has crashed. We use this mainly for A/B-testing for cases where we want to determine the bucket on the client and render a component only after that. So the question would be what your real goal is by ignoring that section of a page when a lot of the other components might be just as dangerous.I've been tracking this issue since #1252 and #6204 so I'll chime in with our current use-case and some thoughts (long post but some background is necessary I think). Like the `canvas´ element, Flash and cookies. Except with some really subjective rules.įurther more if you're concerned about tracking, rather than the information on whenever or not you have JavaScript enabled, there are a lot more technologies that could expose you. As you would not be able to discern the nature of that content without looking it, potentially loading additional resources, there doesn't seem to be a good way to identify 'bad' content here. On certain sites the noscript tag could contain valuable information for you. This would probably the most secure option but also the most complex.

Fork your favorite browser and modify it not to evaluate the noscript part.

The following question could be helpful with this: how to run greasemonkey script before the page content is displayed? Depending on when this script is loaded it might be too late and your browser might try to pre-cache it as well. Use something like a GreaseMonkey script or similar to modify the DOM and remove the noscript part.This won't protect you from tracking pixels that are delivered from the same domain you're visiting though. You could e.g use RequestPolicy and set the scope accordingly. You already seem to be aware of a tool-set that could do that. Block all Request from foreign domains.The solutions I can see in this matter (right now) are the following:

This is also nothing your browser does 'behind your back' and you're probably more concerned about the third party that delivered that graphic than your browser. A browser is unaware of the actual data that is being loaded from a URL just by looking at it and as such would not able to detect a one by one tracking pixel before actually loading it. The article you linked in one of your comments is, in my opinion, about a different topic than your question though.Īs far as the stated scenario in your question is concerned, it's the normal operation of a browser to request resources that are part of page. You're correct that certain browsers are doing more than some would like them to be. I'm not sure where your actual concern is with the information of whenever or not your browser has JavaScript enabled or not. Checking the extension's console, I see no 'Passing. The JavaScript is only getting called for the specific tracking URL. Likewise, a red failure line in the Network tab.Īlso, the URL pre-filtering is working well. The page's console log has an error message net::ERR_BLOCKED_BY_CLIENT for the image fetch. The extension worked fine on the page in question. Its only role is to highlight the extension's entry on the chrome://extensions page. Or delete it and let the browser supply a dummy one.

'description': 'Keeps the browser from fetching tracking URLs',Ĭonsole.log('Website Blocker is running!') See chrome.webRequest for a description of the Chrome browser's API for watching, modifying, or blocking requests in flight. I don't know of way to turn off evaluation of, but in the above example, you could write a short browser extension to cancel any request with a url containing the substring /tr?.
