Open Link in New Tab - FF57 - Refresh loop

So I did, kind of tracked it down - Geek Stuf

Ever since 57 was auto updated on all of me dev boxed that I use for dev purposes I have came across some irritation in logging the user requests. I first made this in the logs a day after initial release of FF57. All requests originated from my IP address, so I thought it was something that caused the abnormality of me having several tabs open. But the things got a bit out of hand.

Over 600 on day 1 from my IP, over 2000 on a day 2. Same session for the same URI. I kind of dismissed it, was busy at a time.

Yesterday had some time to write a few lines of code and it seems that Opening a link in a new tab that I do not automatically switch to - that tab generates a new request in that Tab over and over until manually switching to that Tab. It is also accompanied by ever annoying blue dot/slide indicator on the Tab.

This afternoon I had 6 users/visitors with the same prognoses from 5 different parts of the world. Each over 500 requests, about a second pause between requests. Seems like people just select "Open in a new Tab" and leave it running...

I checked out some other sites, everything seems to be OK, but I can actually reproduce it live.

I have currently have 3 AddOns on FF57: uBlock Origin, NoScript and WebDeveloper toolbar, that is it.

So I am wondering if there is an extra RESPONSE header that my site is sending along with FF having an issue with it.

I have looked at REQUEST Headers and all look the same as before FF57 was deployed on my systems.

Again, this only happens on one site, but from different unrelated users.

Anybody else seen this yet?

P.S. for me the downside of these are IIS logs are bugged down and internal tracking script produces too much DATA.

Could it be a privacy setting in the browser that needs attention?

Privacy: Custom Settings: Except Third Party cookies = never. But again, the site has no Third party scripts/css/images on it,at all. All resources are local.

I tried opening a new tab in Chrome, MS Edge and everything is peachy in those browsers.

I also tried it in FF57 with all Extensions Disabled. The same effect, page reloads in a background tab over and over.

I tried it on Win7, WinServer2008 and windows 10 ---- reloads like "krazey" on all 3, about a second in-between.

Tried it on FF57 for Android on a tablet and on default browser on Blackberry --- everything is OK, no redirects. Tried it on FF50/Developer edition that runs on WindowsXP - no problems.

Again, these are NOT REDIRECTS of any sorts, I checked the raw logs, just endless Reloads on the page itself when the page is open in a New Tab and the Tab is not switched to - in a background.

I could see the headers that are sent by FF New Tab, nothing is out of the ordinary, even compared them to the old headers that FF use to send(I keep log of those).
