Hi, We are now (finally) getting ready to turn on history swipe animations (bug 860493). There have been two major changes since sending out the email below earlier in the year: 1. We will only store snapshots for the 5 most recent pages, instead of 20. 2. Bug 817700 has landed, which gives us async <canvas>.toBlob(). Since this is used every time a snapshot of the page is taken, this greatly helps in terms of performance.
I'm expecting to turn on history swipe animations either today or tomorrow by landing the patch in bug 860493 on inbound. This will also enable the page bounce behavior on OSX (bug 673875). If you have any questions, concerns or feedback, please let me know.
