== In-Page Pop-up Detection ==
This is an experiment to try to train an in-page pop-up detector using [https://mozilla.github.io/fathom/intro.html Fathom].

=== Dataset Curation ===
The first step for this project is curating a dataset of these in-page pop-ups.  In order to do so we're crowd-sourcing an effort through the community to collect the addresses of a large number of pages that show such pop-ups using a [https://docs.google.com/forms/d/e/1FAIpQLSejaT2ia5S4akVM_Zv9OMaAE3n5-S6PmKJG7CuqfwDT5B90sw/viewform Google Form], a [https://mzl.la/2FBbGD8 Firefox Extension] and a [https://chrome.google.com/webstore/detail/in-page-pop-up-reporter/dkpphegmeomaffjanagefmejpeebfcmh Chrome Extension].
