Some tabs opened with middle click are immediately closed when ublock is running.

I notice this issue primarily when middle clicking articles in my RSS feed. I have confirmed that disabling ublock stops this from occurring, but this is obviously not an optimal solution.

I have whitelisted my rss reader URL and this does work around the issue. Not sure if I'd call that a solution though.
