Curious About A Popup

I am not posting this in the support forum because every thing is fine and my system scans clean.
I just wondered if anyone else has had this happen. Last week I was using Firefox and I had recently installed
ZenMate. I was trying to login to Pinterest and got a popup that blocked me from logging in and it said:

Pintress Logo Robot
Uh oh! We've found a bot
It looks like there's a bot running on your network. Send us a message with your IP address and we'll help you get going again.
Your IP is:XXXXXXXXX

Notice the misspelling of Pinterest.
Of course I did not do that. The IP address they showed was not mine either. I closed Firefox and logged into Pinterest using IE. No popup, so I closed IE and reopened Firefox and logged in to Pinterest and no popup this time and has not happened again.
Just curious about this. Any ideas?

 

I guess I am the only one that has got a popup saying I have a bot. Anyone?

 

I would not worry about it.
Keep an eye on your internet usage.

 

Thanks David I wondered if ZenMate was the reason since it was the first time I had seen anything like it.
