I'm getting unwanted pop-ups from a specific page. I have Pop-ups blocked, but it doesn't seem to affect this page

Description of the issue:

When I try to download content from opensubtitles.org it always opens a new window with a link to their extension. I would like to prevent that.

Steps to Reproduce (add as many as necessary):

On this specific subtitle page, for example, if you click “download” (not “download beta”).

Actual Result (gifs and screenshots are welcome!):

Expected result:

Ideally, a blocked pop-up window?

Reproduces how often:

Every time I try to download subtitles.

Operating System and Brave Version(See the About Brave page in the main menu):

macOS Mojave 10.14.3

Brave Version 0.65.118 Chromium: 75.0.3770.80 (Official Build) (64-bit)
