An old and unmaintained add-on, "BlockSite", has been taken over by
a new developer.  The new developer has installed tracking software
to "phone home" and report the user's browsing.

  Reported as a bug, per add-on guidelines.

Ref: https://bugzilla.mozilla.org/show_bug.cgi?id=903799

  This got past AMO partly because the release notes for a new version
did not emphasize the new tracking feature.

The new developer, "wips.com", is in the user tracking business.

Their pitch says:

"Wips.com is the Web Information Company. We measure Internet activity
in order to understand trends, help people discover new content, and
help people make better online decisions. Millions of people download
Wips.com software ("Wips.com Extensions, extensions and add-ons" or
"Extension service") to help measure the web."

"When you use the Extension Service, we collect information about the
websites you visit, the searches you perform using search engines and
when you use the "search" function of the Extension Service, the ways in
which you use various Extension Service features (including whether the
Extension Service is still installed on your computer), and the pages
you view."

The Mozilla add-on page for BlockSite
("https://addons.mozilla.org/en-US/firefox/addon/blocksite/";) doesn't
even have a privacy policy.

There are other "wips.com" add-ons that now need to be checked.  Worse,
they offer development tools for building add-ons which build in their
"tracking" features.   So there may be Mozilla add-ons with their
tracking code that aren't labelled as being from "wips.com".
Once the tracking code has been identified, all add-ons need to
be checked for it.
