My testing is not scientific, but see here: http://www.ghacks.net/2013/07/12/firefox-starting-slow-try-disabling-hardware-acceleration/ Possibly related to: https://bugzilla.mozilla.org/show_bug.cgi?id=721892
It's a pretty bad advice to disable HWA, because it used largely in content rendering and compositing, so it will degrade the perfs during browsing, which is the main part of the user experience. Are you able to reproduce this issue with Firefox 22 and old versions? (use a clean profile https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles)
It is actually not a big issue for me - I would never disable HWA. I was just highlighting it in case it pointed to a real bug. Some more unscientific testing with a clean profile and yes, it's slower. Happy for the bug to be closed if you don't think it's an issue.
Can anyone reproduce with more "scientific" testing?
Closing this as it doesn't impact noticeably.
