I have been reporting this issue over the span of numerous builds, current running v4 126.96.36.199 | The scope of this issue I would have to agree is way beyond cosmetic. There have been some through this very long thread that have stated they never see this issue, there have been others that stated same, regardless of build in the v4 family, regardless of OS in the Win family are continuing to see this. I am an IT Pro, so I know it's an annoyance popup when I see it. I would have to agree for an at-home, business or corporate user, it is difficult to differentiate between a genuine popup flag and an annoyance. Hoping this bug is not carried over to the v5 family as I am very much looking forward to the final release. The bug has been cited on the Beta, the preceeding link would be one that I have found since I have not been following the Beta releases threads.
