User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:21.0) Gecko/20130113 Firefox/21.0 Build ID: 20130113031019 Steps to reproduce: 1. Create fresh profile 2. Make a Yahoo mail account. Make sure Inbox has some mails. 3. Come to this page. 3. Ctrl+click on mail.yahoo.com 5. try to scroll in the tab while yahoo is loading in the background tab. Actual results: Janks. CPU usage is 100%. Yahoo has always been quite sucky. But AFAIK, this particular bug is a recent regression. Probably less than 1 month old. ******************** http://people.mozilla.com/~bgirard/cleopatra/#report=74100f6a61e10ffdeb9b4288457d5269c363cd2f Expected results: Smooth loading.
Is this still bad when you set firefox cache size to 0( via advanced/network settings)?
It janks lesser, but still noticable.
FWIW, the SPS profiler doesnt record the profile for more than 3-4 seconds on yahoo mail. Even if the profiler runs for ~12-13 seconds, the profile shows a time of only ~3.4 seconds. Is this a bug ?
This has worsened in the past few days. Its so bad now that i cringe when i see a new mail notification, and have to open ymail. And i use a SSD.
Confirmed the Jank against Mozilla/5.0 (Windows NT 6.1; WOW64; rv:22.0) Gecko/20130320 Firefox/22.0 ID:20130320031103 CSet: 8156df33b757, no 100% CPU Usage on my End though. fresh SPS: http://people.mozilla.com/~bgirard/cleopatra/#report=09cc1e866f7de4f7459e917ea5dcaf974518933c
