Description

As you can see in the first screenshot, the page as the browser is pseudo-blocked, and it only happens when it makes the cloudflare check against bots.

At the time that the check is passed to disable ublock in tresdaos.com you can navigate normally through the page (ublock enabled inside does not give problems), until at the time it decides to make another check and we return with the problem.

Although in the screenshot you can see extensions, I have also found that with ublock as the only enabled extension the problem is reproduced.

In an effort to see what could be the cause, I have disabled filter lists and I have identified 3 lists that seem to induce the problem:

• Ublock filters - Ads

• AdGuard - Ads

• My filters (I have used several filters within the Ublock filters - Ads list).

And I have come to see which filters that I apply in my list generate the problem:

• ##+js(noeval-if, /chp_?ad/)

• ##+js(no-fetch-if, googlesyndication)

• ##+js(noeval-if, /fairAdblock|chp_adblock|adsbygoogle.js/)

Disabling those filters plus the lists loads the page but you can see in the second screenshot the result, a warning pops up (I have applied filters to remove parts of the page).

Other extensions used

I have tried with the extensions I use (which are not few), as well as with Ublock only.
