I can confirm the Problem with Global Menu Bar Integration for Ubuntu 12.04, Firefox 20. -- 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/1132234 Title: Firefox unresponsive for a few seconds if using the globalmenu extension Status in “firefox” package in Ubuntu: Confirmed Bug description: I'm using firefox with the globalmenu extension. After selecting the firefox window, the first attempt to interact with the program (i.e. open or close tab, select a tab, scroll down the webpage etc.) makes the program unresponsive and the CPU runs at 100% for a few seconds. Afterwards, the required action is performed and the program works fine until the focus is moved to another window and back to the firefox window, then the problem appears again. I've noticed that disabling the globalmenu extension solves the problem. I'm on Ubuntu 12.10 with unity 6.12.0 firefox 19.0 firefox-globalmenu 19.0 (in the firefox add-ons page is described as Global Menu Bar Integration 3.7.1) also affects firefox 20 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1132234/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
