Tutorials/Howtos • Cloudflare Turnstile: ηMatrix/uBlock guide for proper function

ηMatrix (aka eMatrix): Make sure you are using the latest version: https://addons.palemoon.org/addon/ematrix/

Its default settings will break Cloudflare's verification process.

1. Go to the extension's "My rules" section.
2. Temporary rules / Press "Edit".
3. Go to end of the existing rules, add a new line and paste the two lines below. Don't overwrite or alter any existing rules. Make sure they are entered as two, separate lines.

CODE:

* challenges.cloudflare.com frame allow* challenges.cloudflare.com script allow

1. Press the "Save" button, then "Commit". If done correctly, they should now also appear on the left "Permanent rules" section. That's it.

====================================

uBlock Origin "Legacy": Make sure you are using the latest version. UCyborg's fork is currently the recommended one: https://github.com/UCyborg/uBlock-for-f ... y/releases

If using JustOff's older fork, it's best to fully uninstall it first. Backup your uBO settings, if you want to restore them later. If you are not sure what you are doing, start clean with UCyborg's new fork.

uBO's default settings will not break Cloudflare's verification process. Breakage is uncommon with uBO and will only occur:

1. With hard-core filterlists that may block Cloudflare entirely. If such lists are active, they need to be disabled or removed.
2. With certain advanced settings e.g. enabling the so-called "medium mode" and of course the "hard mode". These are not some special modes you can enable with one click on uBO's UI. They are a combination of non-default settings, to be enabled as described in the linked articles.

If not using such advanced modes, you don't need to do anything on uBO.

If for whatever reason you are using an advanced blocking mode, you need to allow 3rd-party frames and 3rd-party scripts on every website that implents the Cloudflare check. uBO is less flexible and granular for this job than eMatrix. It is recommended to use the latter for this purpose. If you insist on using uBO for this kind of blockage, then:

1. Visit the website that performs the CF check.

2. Make sure to "green" the two indicated boxes below. The ones in the right column, as indicated. The left ones should already be red, if using medium/hard blocking mode: (they are not red in the screenshot below)

3. Repeat steps 1+2 on each website.

On my example, I applied this on the Pale Moon forum (which doesn't use CF - it's just an example). If done correctly, these rules should appear on uBO's "My rules" section:

CODE:

forum.palemoon.org * 3p-frame allowforum.palemoon.org * 3p-script allow

Of course, the website you added will be there instead of "forum.palemoon.org".
