When I surf to https://plus.google.com/ i can no longer click on the red notification icon and see my notifications. If I disable https everywhere it works fine. I just found out that if I use the url https://plus.google.com/u/0/ then everything works ok with https everywhere. But it seems that google no longer redirects to that page automatically, so that might be why this issue surfaced a few weeks ago. Note: I use firefox 14 on Linux if that matters.
