I hired an electrician to rewire an outlet under my sink so that the switch above the sink can control only one of the two plugs. When he was done, I used the outlet tester and found that he hadn’t properly connected the ground wire. I wasn’t planning on connecting an appliance that needed grounding, but I think every outlet in the house should be grounded anyways as a matter of course. Got him to fix it before he left. That $9 I spent 7 years ago paid off as far as I’m concerned.
I’ve been having the same problem even on my home IP. It only happens when I’m using Firefox though. If I use Chrome, and oddly enough change my IP by routing through my rented VPS and pass a few captchas then Google will eventually start to trust Firefox from my home IP. It’s bizarre and Google is really starting to piss me off because I’m wasting so much time on this shit.
