Would someone on x86_64 mind installing this addon? There is a catch though - it will only work in the current Firefox beta (from https://launchpad.net/~mozillateam/+archive/firefox-next).
This contains a bunch of changes which might slightly improve the speed of building menus (buried amongst the refactoring in http://bazaar.launchpad.net/~extension-hackers/globalmenu- extension/trunk/revision/301?remember=291&compare_revid=291). However, I don't expect those to make all that much difference here and without being able to recreate the problem, I'm not even sure where the performance issues are. With this version of the addon installed, could you also please try running Firefox with GLOBAL_MENU_NO_ICONS=1 in the environment and see if that makes a difference? ** Attachment added: "globalmenu-extension x86_64 2.5pre r301" https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/964584/+attachment/2940059/+files/globalmenu.xpi ** Changed in: firefox (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/964584 Title: Firefox hangs temporarily everytimes it receives the focus Status in “firefox” package in Ubuntu: Incomplete Bug description: In 12.04 beta, with unity, every times firefox gets the focus, it blocks for a couple of seconds (~10 second on my laptop) while loading all the processors fully.
