Facebook popup has taken over my NY Times website
In my Facebook page if I start to fill in a comment but then click to go somewhere else before I post my comment, I get a popup saying
"This page is asking you to confirm that you want to leave - data you have entered may not be saved."
I suppose everyone gets the same.
Now it is popping up in my NY Times pages. Whenever I click a link to go to another page, or click to Go Back, I get that popup. It has nothing to do with anything I have entered anywhere, it just comes at me every time I go anywhere in the whole NY Times website. Big Bummer!!!
I'm a software engineer and I know at least some about how things work, but this one I have no idea about. Does anyone here know where in Firefox this could be coming from? I havent found it in any other website [so far], and it doesnt happen in IE.
I suspect that whatever Facebook has for calling that popup, something of it is getting stored in Firefox but pointing to nytimes.com by mistake.

You can set this pref to true on the about:config page to disable this notification.
- dom.disable_beforeunload = true
You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.
This warning messages comes up on various sites, for example Reddit, if you start typing a comment and decide not to continue and try to close the tab. It is a standard event sites can hook into, not specific to Facebook. (beforeunload on MDN)
What's hard to understand is why a script in the New York Times page thinks you have entered data into a form field if you haven't done that. Hmm. Could an extension be involved??
"My Antispyware" may be going a bit overboard (or are they ?) :
