I use uMatrix v1.0.0 (
uMatrix.firefox.xpi) on Firefox ESR v52.1.2 and have configured uMatrix to disable all scripts by default. But somehow, inline scripts are still executed on
http://rule34hentai.net/ site. Below are the first few lines of my uMatrix Rules (minus host specific rules).
matrix-off: about-scheme true
matrix-off: addons.about-scheme false
matrix-off: chrome-extension-scheme true
* * * block
* * css allow
* * image allow
* 1st-party cookie allow
* 1st-party doc allow
The result on that site is that after about 5 seconds, it replaces the page with a message saying that an adblocker is detected. It’s not a browser redirect through HTML META Refresh element since there’s no such HTML element within the HTML source code and the URL stays the same.
This problem doesn’t occur for WebExtension version of uMatrix. I’ve tested it on Firefox v54 and Chromium v43.
