I hate click-through trackers. This extension will circumvent click-through trackers on Twitter and maybe Facebook.
I didn't test the Facebook script very robustly because I don't use Facebook. I didn't test the extension at all on Chrome because I don't use Chrome.
Links on Twitter's web interface point to a shortened t.co URL, but their original
URLs are still in the DOM in the link's
In the current Twitter web UI, it is also in the
This lets us replace the link's
href attribute on click, before the browser navigates.
Unfortunately, when a URL has a Twitter Card representation, there is no destination URL in the DOM at all, so we can't circumvent t.co here.
On the mobile site, the page loads asynchronously in a React application, so the
event listeners are set on
document.body rather than the feed column (which
doesn't exist a page load).
Facebook links to external pages all point to the page
with the desintation URL urlencoded in a query param. On
mouseover, the link's
href attribute is replaced with the final URL, and the l.facebook.com/l.php
URL is placed in the
data-lynx-uri attribute. Hovering over the link will
display the tracker URL in the status bar the first time, but afterwards it will
appear to link directly to the destination URL. On click, the
href is swapped
out again for the one stored in
We can attach a listener to
mousedown which outright deletes the attributes
holding the tracker URL, and additionally we can remove any
from the final URL.
N.B. I don't use Facebook enough to care about how well this works.
