By the end of 2017, we will transition to <a class=\"external text\" href=\"https:\/\/wiki.mozilla.org\/WebExtensions\" target=\"_blank\" rel=\"nofollow\">WebExtensions<\/a> as the standard for creating add-ons. Over the same period of time, existing methods for add-on development such as XUL\/XPCOM will be deprecated. <a class=\"external text\" href=\"https:\/\/developer.mozilla.org\/Add-ons\/Working_with_multiprocess_Firefox\" target=\"_blank\" rel=\"nofollow\">Multi-process Firefox<\/a> (aka Electrolysis, or e10s) is also rolling out, which means some developers will have to update their add-on more than once. All this on the heels of <a href=\"https:\/\/blog.mozilla.org\/addons\/?s=signing\" target=\"_blank\">add-on signing<\/a>.<\/p>\n<p>In the past few weeks, we&#8217;ve been gathering all the information and resources we could to help developers navigate the upcoming changes.

A few notable pieces of information you&#8217;ll find:<\/p>\n<ul>\n<li>A <a href=\"https:\/\/compatibility-lookup.services.mozilla.com\/\" target=\"_blank\">lookup tool<\/a> you can use to see if your add-on will be impacted, and if so what the recommended migration path is.<\/li>\n<li>A <a href=\"https:\/\/docs.google.com\/a\/mozilla.com\/forms\/d\/1PtRXcs9UHVMjge77b2QHpvUE4Xpz7erbTAOTYdt5q5k\/viewform\" target=\"_blank\">survey<\/a> you can use to tell us which WebExtension APIs you need, so we can better prioritize them.<\/li>\n<li>A <a href=\"https:\/\/wiki.mozilla.org\/Add-ons\/developer\/communication#Timeline_of_Changes\" target=\"_blank\">timeline<\/a> of changes that includes dates to the best of our knowledge. This is a working doc and will be updated as we learn of new information.<\/li>\n<li>A <a href=\"https:\/\/wiki.mozilla.org\/Add-ons\/developer\/communication#Add-on_Developer_Communication_Calendar\" target=\"_blank\">calendar<\/a> you can add to see upcoming meetings, blog posts, and office hours. We will also be adding release milestones to the calendar in the coming weeks.<\/li>\n<\/ul>\n<p>Blog posts and other documentation related to the transition are added <a href=\"https:\/\/wiki.mozilla.org\/Add-ons\/developer\/communication#Blog_Posts_and_Other_Resources\" target=\"_blank\">here<\/a> as they&#8217;re created. We have more content queued up, and as you can see we could use even more. If you&#8217;re interested in writing about your experience creating a WebExtension add-on, or becoming e10s compatible, or anything else that others might find relevant, please <a href=\"https:\/\/docs.google.com\/spreadsheets\/d\/156xsgIMH7Lv0-zXowMvrSO9bIRTCaCOwakFrPlkR4Js\/edit#gid=0\" target=\"_blank\">sign up here<\/a>.<\/p>\n<p>We&#8217;ll keep releasing information on the <a href=\"https:\/\/wiki.mozilla.org\/Add-ons\/developer\/communication\" target=\"_blank\">wiki<\/a> as they become available.
