"Requests to the server have been blocked by an extension" blocking download button on some deviantART pages

[qwerty12]

With Chromium 35.0.1916.153 (274914) and µBlock 0.2.1.2, going to http://satya164.deviantart.com/art/Conky-Google-Now-366545753, for example, will show the "Requests have been blocked" message as in the screenshot and cover the download box. This does not happen on all deviantART pages though (http://zagortenay333.deviantart.com/art/Conky-Harmattan-426662366 seems to be OK) and sometimes I won't even see the "Requests have been blocked" message - instead, I simply won't be able to click on the download button save for a tiny, tiny area around the top-left edge of the button. Using the Developer tools to delete <div class="dp-ad-chrome atf-right-300x250 dp-ad-visible" style="top: 13px; left: 1035px;"> lets me workaround it.

Apologies if this is already covered by another bug. Thanks.

This could be related to #53, behavior is the same.

Meanwhile, I used the element picker to create a cosmetic filter:

deviantart.com##.dp-ad-chrome.atf-right-300x250.dp-ad-visible

Seems to work. You may try this until I figure a real fix for the bug.

[gorhill]

Actually, this one works better, you should not even see the placeholder at all:

deviantart.com##.dp-ad-chrome.atf-right-300x250

Awesome. Thank you very much.

Fixed in 0.2.3.2.
