====Android and Desktop====* Deprecated - its recommended to use Firefox 31 or higher instead (see below)* . If testing on these versions is necessary, an [https://addons.mozilla.org/en-US/android/addon/mkt-app-reviewer-certs/ add-on] can be installed to add reviewer certificates.

No add-on needed. You just need to set the preference ''dom.mozApps.use_reviewer_certs'' to ''true''. TODO: For Desktop, you also include domneed to edit another pref to add the url for Marketplace-dev.mozApps.signed_apps_installable_from

# In the URL field, type ''<code>about:config'' </code> and hit enter.

# In the Name field, type ''<code>dom.mozApps.use_reviewer_certs''</code>. NOTE: this name is case sensitive, so make sure to type it exactly as shown. The lower case ''dom'' is often (mis-)corrected to ''Dom.''

# In the URL field, type ''<code>about:config'' </code> and hit enter.

# In the Name prompt, type ''<code>dom.mozApps.use_reviewer_certs''</code>. NOTE: this name is case sensitive, so make sure to type it exactly as shown.# For the next prompt chose ''true'' as the boolean valueand click OK.# Search for <code>dom.mozApps.signed_apps_installable_from</code> and double click the line.# Change the text to <code>https://marketplace.firefox.com,https://marketplace-dev.allizom.org</code>. Make sure there's no space after the comma separating the two urls.# Once you press Okay OK the preference is created updated and you're done!
