===Mr Robot promotional web extension===
In December 2017 Mozilla, in collaboration with the Mr Robot team, created and included by default a web extension in [https://wiki.rossmanngroup.com/wiki/Firefox Firefox] called Looking Glass.<ref name=":1">Mozilla addressing the Looking glass incident

[https://blog.mozilla.org/en/products/firefox/retrospective-looking-glass/ ss/]</ref> While the extension was disabled by default, many users were confused and worried to discover a unknown extension installed in their browser with a cryptic description "MY REALITY IS JUST DIFFERENT THAN YOURS".<ref>Firefox's users worried about the looking glass extension  https://www.reddit.com/r/firefox/comments/7jh9rv/what_is_looking_glass/</ref> This description was later expanded to include references to Mozilla's collaboration.<ref>Locking glass extension description changed https://github.com/mozilla/addon-wr/commit/21ff53d2d5baab591d29b4ea5847d74cb6901b2c</ref>

When activated, the extension executes code on all websites visited by the user, searching for all words matching a list. Every match is then wrapped in HTML span tags,<ref>looking glass extension injecting HTML https://github.com/mozilla/addon-wr/blob/da464ac8f1c3b089405ca96fc68b999d2b624ef4/addon/webextension/content-script.js#L27</ref> and tooltips are injected to be displayed when the user hovers over these matches. CSS code is injected to make the words appear upside down and the tooltips work.<ref>Looking glass extension injecting CSS https://github.com/mozilla/addon-wr/blob/da464ac8f1c3b089405ca96fc68b999d2b624ef4/addon/webextension/background.js#L78</ref> Also three specific websites did have their headers changed to have a value "x-1057"  injected.

While the extension could in rare occasion break some website with the HTML and CSS injection, it did not do anything malicious or dangerous. The extension was not collecting any personal information at all, but Mozilla admitted it had made a mistake in its response addressing the issue.<ref name=":1" />

<blockquote>'''A SHIELD study must be designed to answer a specific question.'''

We evaluated Looking Glass based on whether or not it upheld user privacy. Since it did not collect any data, we felt that it was safe. In retrospect, not capturing data was a strong indicator that this was not a good SHIELD study candidate, so we’re making sure we’re going to specifically evaluate future studies based on this criteria to ensure that we don’t repeat our mistake.</blockquote>
