Many memory bugs have been filed and fixed for Firefox, but add-ons are also a significant factor in how much memory is being used.<\/p>\n<p><strong>There is an ongoing effort to track and stomp <a href=\"https:\/\/bugzilla.mozilla.org\/show_bug.cgi?id=700547\">memory leaks in add-ons<\/a>.<\/strong> Here&#8217;s where you can help, either by testing the add-ons you created, or testing the add-ons you use. Please read the article on <a href=\"https:\/\/developer.mozilla.org\/en\/Zombie_Compartments\">Zombie Compartments<\/a>, particularly the add-ons section. It should give you some pointers on how to find leaks and how to avoid them. The short version is: <strong>don&#8217;t hold any references to DOM objects after the document is closed<\/strong>.<\/p>\n<p>The AMO review team is already aware of this, and we have added memory leaks to our testing policies. Add-on versions that leak generally won&#8217;t get full review.<\/p>\n<p>There are also great news from the MemShrink camp. With the resolution of <a href=\"https:\/\/bugzilla.mozilla.org\/show_bug.cgi?id=695480\">bug 695480<\/a>, whole classes of compartment leaks have been resolved on the Firefox side. This means that even if an add-on holds on to DOM references when it shouldn&#8217;t, they will be properly claimed. But this doesn&#8217;t mean that you shouldn&#8217;t test and fix your code! This fix will be introduced in Firefox 15, so it&#8217;s some away anyway.<\/p>\n<h3>Firefox 12 Compatibility<\/h3>\n<p>The <a href=\"http:\/\/blog.mozilla.org\/addons\/2012\/03\/15\/compatibility-for-firefox-12\/\">Firefox 12 compatibility blog post<\/a> is up. It also includes some major changes coming in Firefox 13, so make sure to give it a read. The Firefox 12 compatibility bump should happen very soon.<\/p>\n<p>The compatibility work for Firefox 13 is still pending. I promise to finish it soon!<\/p>\n","protected":false},"excerpt":{"rendered":"<p>I post these updates every 3 weeks to inform add-on developers about the status of the review queues, add-on compatibility, and other happenings in the add-ons world.
