For me this makes HUD unusable in Firefox 13.0 (and 12.0 before that). I do have 748 bookmarks in 133 folders.
Intel® Core™2 Duo CPU T6400 @ 2.00GHz × 2 RAM: 3 GB I was testing it by typing "new tab" in HUD (yes I know it's quicker with Ctrl+t). The new tab took about 7 sec to show up and become responsive the first time round. With each repetition, the waiting time got longer. After a about 20-30 trials, the waiting time got to about 30-50 seconds (inconsistent) before Firefox became responsive again (it fades out after about 10 sec and comes back some time later). I restarted Firefox and the hud-service and tried again, with the same results. Using HUD to choose Firefox->Preferences also causes the browser to fade out and about 15-40 sec later the Preferences dialogue shows up and becomes responsive immediately or after about a 5-10 sec gap. Using menus or keyboard shortcuts to produce a New Tab or get to Preferences produces immediate results even after a long session of HUD testing. After the test: hud-service: Memory = 381.3 MiB, Virtual Memory = 424.2 MiB -- 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/1005174 Title: HUD Service high CPU usage with Firefox Status in The Application Menu: Confirmed Status in Unity: Confirmed Status in “firefox” package in Ubuntu: Invalid Status in “indicator-appmenu” package in Ubuntu: Confirmed Bug description: When using HUD to access Firefox menus, it will use a high amount of CPU (around 70%), even after Firefox is closed. It looks like its trying to index Firefox menus (speacially the bookmarks menu, that has a lot of entries). Steps to reproduce: - You need a Firefox install with hundreds of bookmarks. - Start Firefox - Start the Hud and try to search a item that it's on your bookmarks menu. - See the high CPU usage of unity-pane-service and hud-service.
