personalized browsing experience. Most add-ons are created with the best intent, providing users with useful and delightful features. However, add-ons can also be used to compromise personal data and security.</p> <p>When Mozilla becomes aware of add-ons that go against user expectations or otherwise risk user privacy and security, it takes steps to block them from running in Firefox. This may happen proactively, or in response to an abuse report. When an extension is blocked, it is disabled in Firefox and users are not able to override the block.</p> <p>The following describes Mozilla’s common practices for dealing with add-ons that appear to violate the <a href="/documentation/publish/add-on-policies/">Add-on Policies</a>. Authoritative information on the conditions for removing or revoking add-ons can be found in the <a href="/documentation/publish/firefox-add-on-distribution-agreement/">Firefox Add-on Distribution Agreement</a> and the <a href="/documentation/publish/add-on-policies/">Add-on Policies</a>.</p> </div> <div class="page-hero-cta"> </div> </div> </article> </div> </section>   <section id="security-over-choice" class="module"> <aside class="module-aside table-of-contents"><div class="table-of-contents-inner"> <h6>Contents</h6> <ol><li><a href="#security-over-choice">Security Over Choice</a></li><li><a href="#blocking-criteria">Blocking Criteria</a></li><li><a href="#developer-outreach">Developer Outreach</a></li><li><a href="#requesting-a-block">Requesting a Block</a></li><li><a href="#blocking-other-types-of-third-party-software">Blocking Other Types of Third Party Software</a></li> </ol> </div> </aside> <article class="module-content grid-x grid-padding-x"> <div class="cell small-12"> <h2>Security Over Choice</h2> <p>When deciding whether to block an add-on from running in Firefox, we ask whether the risk is so great that it outweighs the user’s choice to install the software, the utility it provides, as well as the developer’s freedom to distribute and control their software. If we encounter a situation where we cannot make a clear-cut decision, we will err on the side of security to protect the user.</p> </div> </article> </section>   <section id="blocking-criteria" class="module"> <article class="module-content grid-x grid-padding-x"> <div class="cell small-12"> <h2>Blocking Criteria</h2> <p>Blocking is reserved for add-ons with the following characteristics:</p> <ul> <li>They appear to intentionally violate policy</li> <li>They contain critical security vulnerabilities</li> <li>They compromise user privacy</li> <li>They severely circumvent user consent or control</li> </ul> <p>Add-ons that appear to be clones, repeats or close copies of already blocked add-ons will also be removed. If an issue is known to affect only a subset of versions, the block may be applied to the affected versions specifically. Add-ons that contain obfuscated or comparably unreadable code will also be blocked.</p> </div> </article> </section>   <section id="developer-outreach" class="module"> <article class="module-content grid-x grid-padding-x"> <div class="cell small-12"> <h2>Developer Outreach</h2> <p>When we decide to block an add-on, we may reach out to the developer if we believe the issue can be remedied. As the security of users may be at stake, we require developers to respond within three days. If no response is received within this timeframe, or the developer isn’t able to address the issue, we may proceed with the block.</p> <p>More commonly, we will not reach out to developers prior to blocking if it appears that the add-on is intentionally violating our policies, or the violation is sufficiently severe.</p> </div> </article> </section>   <section id="requesting-a-block" class="module"> <article class="module-content grid-x grid-padding-x"> <div class="cell small-12"> <h2>Requesting a Block</h2> <p>If you have encountered an add-on that you believe meets the criteria for being blocked, you may <a href="http://bugzilla.mozilla.org/form.blocklist">request a block</a>. Note that developers cannot request a block of their own add-ons.</p> <p>Mozilla only blocks add-ons based on the <a href="/documentation/publish/firefox-add-on-distribution-agreement/">Firefox distribution agreement</a> and <a href="/documentation/publish/add-on-policies/">add-on policies</a>. When requesting a block, please read these carefully as the policies do allow certain forms of monetization and data collection.</p> </div> </article> </section>   <section id="blocking-other-types-of-third-party-software" class="module"> <article class="module-content grid-x grid-padding-x"> <div class="cell small-12"> <h2>Blocking Other Types of Third Party Software</h2> <p>In addition to add-ons, Mozilla may also block other types of software that pose a risk to the user.</p> <p>Mozilla may limit hardware acceleration features of graphics cards for certain graphics driver versions in accordance with the <a href="https://wiki.mozilla.org/Blocklisting/Graphics">graphics driver blocks</a> policy. This is done for stability reasons, to avoid driver crashes that would interrupt the user.</p> </div> </article> </section>  <section class="module meta-data"> <article class="module-content grid-x grid-padding-x"> <div class="cell small-12"><p><span class="meta-label contributors">Contributors:</span> <a href="https://github.com/caitmuenster/" title="View caitmuenster on Github">caitmuenster</a> <a href="https://github.com/kewisch/" title="View kewisch on Github">kewisch</a> </p><p><span class="meta-label date">Last update:</span> <a href="https://github.com/caitmuenster/" title="View caitmuenster on Github" itemprop="author" itemscope="" itemtype="http://schema.org/Person"><span class="p-author h-card" itemprop="name">caitmuenster</span></a> <time class="dt-published" datetime="2021-05-04T00:00:00+00:00" itemprop="datePublished">May 04, 2021 </time> </p></div> </article> </section> <section class="module up-next"> <article class="module-content grid-x grid-padding-x"> <div class="cell small-12"> <h6>Up Next</h6> </div> <a href="/documentation/publish/third-party-library-usage/" class="cell auto tile tile-block-link"> <div class="block-link"><p>Publish</p><h5>Third Party Library Usage</h5> </div> </a> <a href="/documentation/publish/what-does-review-rejection-mean-to-users/" class="cell auto tile tile-block-link"> <div class="block-link"><p>Publish</p><h5>What does review rejection mean to users?</h5> </div> </a> <a href="/documentation/publish/signing-and-distribution-overview/" class="cell auto tile tile-block-link"> <div class="block-link"><p>Publish</p><h5>Signing and distribution overview</h5> </div> </a> </article> </section> </main> <aside class="documentation-topics"> <div class="grid-container grid-x grid-padding-x"> <div class="cell small-12"> <h6>Documentation Topics</h6> <ul> <li><a href="/documentation/develop/">Develop</a></li> <li><a href="/documentation/publish/">Publish</a></li> <li><a href="/documentation/manage/">Manage</a></li> <li><a href="/documentation/enterprise/">Enterprise</a></li> <li><a href="/documentation/themes/">Themes</a></li> </ul> </div> </div> </aside> <aside class="panel social"> <div class="grid-container grid-x grid-padding-x"> <div class="cell small-12"> <h2>Connect With Us</h2> </div> <div class="cell small-12 large-3"> <h4>Twitter</h4> <p>For developers: <br><a href="https://twitter.com/mozamo" class="twitter">@mozamo</a></p> <p>For end users: <br><a href="https://twitter.com/rockyourfirefox" class="twitter">@rockyourfirefox</a></p> </div> <div class="cell small-12 large-4"> <h4>More</h4> <p><a href="https://wiki.mozilla.org/Matrix" class="irc">Matrix</a></p> <p><a href="https://discourse.mozilla.org/c/add-ons/" class="irc">Community forum</a></p> </div> <div class="cell small-12 large-5"> <h4>Extensions Developer Newsletter</h4> <p>Stay up-to-date on news and events for Firefox extension developers.</p> <div class="newsletter" id="newsletter_wrap">  <form id="newsletter_form" name="newsletter_form" action="https://www.mozilla.org/en-US/newsletter/" method="post" data-no-csrf=""> <input type="hidden" id="fmt" name="fmt" value="H"> <input type="hidden" id="newsletters" name="newsletters" value="about-addons"> <div id="newsletter-errors" class="newsletter-errors"></div> <div id="newsletter_email" class="form_group"> <label for="email" class="visually-hidden">Email Address</label> <input type="email" id="email" name="email" class="form_input" required="" placeholder="Email Address" size="30"> </div> <div id="newsletter_privacy" class="form_group form_group-agree"> <input type="checkbox" id="privacy" name="privacy" required=""> <label for="privacy">I’m okay with Mozilla handling my info as explained in this <a href="https://www.mozilla.org/privacy/websites/">Privacy Notice</a>.</label> </div> <div id="newsletter_submit"> <button type="submit" class="button btn btn-success">Sign up</button> </div> </form> <div id="newsletter-thanks" class="newsletter-thanks"> <h6>Thanks!
