Title: firefox hangs up compete laptop for no apparent reason Status in “firefox” package in Ubuntu: New Bug description: At various occasions the firefox browser just hangs and not even the mouse pointer responds. Sometimes after some time there is a message about an irresponsive script. Mostly after waiting a lot of minutes and closing firefox it works again. I do not have this problem on other machines or other os'es. Don't seem to have the problem in Chromium either. Seems like a firefox bug to me ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: firefox 28.0+build2-0ubuntu1 ProcVersionSignature: Ubuntu 3.13.0-19.39-generic 3.13.6 Uname: Linux 3.13.0-19-generic x86_64 NonfreeKernelModules: wl AddonCompatCheckDisabled: False ApportVersion: 2.13.3-0ubuntu1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: ubuntu 1932 F.... pulseaudio BuildID: 20140317144912 Channel: Unavailable CurrentDesktop: Unity Date: Mon Mar 24 18:35:37 2014 Extensions: extensions.sqlite corrupt or missing ForcedLayersAccel: False IfupdownConfig: # interfaces(5) file used by ifup(8) and ifdown(8) auto lo iface lo inet loopback IncompatibleExtensions: Unavailable (corrupt or non-existant compatibility.ini or extensions.sqlite) InstallationDate: Installed on 2014-03-04 (20 days ago) InstallationMedia: Ubuntu 14.04 LTS "Trusty Tahr" - Alpha amd64 (20140303) IpRoute: default via 192.168.1.1 dev wlan0 proto static 192.168.1.0/24 dev wlan0 proto kernel scope link src 192.168.1.108 metric 9 Locales: extensions.sqlite corrupt or missing PrefSources: prefs.js Profiles: Profile0 (Default) - LastVersion=28.0/20140317144912 RelatedPackageVersions: rhythmbox-mozilla 3.0.1-1ubuntu16 totem-mozilla 3.10.1-1ubuntu3 RunningIncompatibleAddons: False SourcePackage: firefox Themes: extensions.sqlite corrupt or missing UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 12/26/2013 dmi.bios.vendor: LENOVO dmi.bios.version: 92CN26WW(V1.06) dmi.board.asset.tag: NO Asset Tag dmi.board.name: AIUU1 dmi.board.vendor: LENOVO dmi.board.version: 31900042STD dmi.chassis.asset.tag: NO Asset Tag dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Lenovo Yoga 2 11 dmi.modalias: dmi:bvnLENOVO:bvr92CN26WW(V1.06):bd12/26/2013:svnLENOVO:pn20332:pvrLenovoYoga211:rvnLENOVO:rnAIUU1:rvr31900042STD:cvnLENOVO:ct10:cvrLenovoYoga211: dmi.product.name: 20332 dmi.product.version: Lenovo Yoga 2 11 dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1296860/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
