I fixed an issue where add-on was waiting until the page finished loading before removing recommended posts. This should prevent any images from recommended posts from ever loading, which improves loading times and reduces bandwidth used. This should fix the problem where some users did not see the add-on having any effect.

I have also removed two seemingly unused class matches. (".logo_anchor_rainbow" and ".logo_dot")
Finally, the add-on should now remove sponsored posts as well.
