For many users with add-ons installed this will significantly reduce Firefox\u2019s memory consumption, without requiring upgrades to those add-ons.<\/p><\/blockquote>\n<p>As Joe Biden might say, this is a <em>big effing deal<\/em>, and I am really looking forward to Firefox 15 being released in 6 short weeks! Although Nicholas&#8217; post is long it is a great read if you are at all interested in these changes, and even if you aren&#8217;t it is worth skipping to the bottom where he shares some anecdotal feedback from users.<\/p>\n<p>Another similar improvement coming down the pipe ( as early as Firefox 17! ) is the new &#8216;nukeSandbox&#8217; technique implemented by the SDK &#038; Platform teams to ensure that JavaScript sandboxes created by add-ons are cleaned up correctly &#8211; this work was tracked in bugs <a target=\"_blank\" href=\"https:\/\/bugzilla.mozilla.org\/show_bug.cgi?id=769273\">769273<\/a> ( &#8220;CCW &#8220;Nuke&#8221; feature for sandboxes&#8221; ) and <a target=\"_blank\" href=\"https:\/\/bugzilla.mozilla.org\/show_bug.cgi?id=\">775067<\/a> ( &#8220;Start using Cu.nukeSandbox&#8221; ). <\/p>\n<p>While we do not expect the same dramatic level of improvement in memory usage as will be introduced by the changes in Firefox 15, when dealing with add-ons and memory leaks, even incremental improvements can yield real benefits for Firefox users. This particularly affects SDK-based add-ons as we make heavy use of sandboxes to enforce our security model.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Memshrink lead Nicholas Nethercote posted another excellent update yesterday on memshrink progress in general and in particular on how Firefox 15 ( coming soon to the beta channel! ) is &hellip; <a class=\"go\" href=\"https:\/\/blog.mozilla.org\/addons\/2012\/07\/19\/more-memshrink-news-or-how-awesome-is-firefox-15\/\">Read more<\/a><\/p>\n","protected":false},"author":316,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[7117,44,588,742],"tags":[121],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v22.5 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>More memshrink news, or how awesome is Firefox 15?
