Affected: 32.0a1 Nightly as of today 31.0a2 Aurora as of today STR: - Have enough entries in the history for the newtab-page to be filled up in case of a tile being removed; ad-tiles in current Nightly will be enough. - Make the window smaller than defined by browser.newtabpage.rows/.columns (my current configuration is showing 2 rows and 3 columns with the default values of 3/3) - Pin and unpin a tab; do it a couple of times if necessary. AR: Unpinning causes the whole grid to bounce a bit to the left and back to the right ER: No bouncing.

Sorry, fixed the typo.

Dupe of bug 1007993?

[Tracking Requested - why for this release]: Need to know if this should be fixed for 33.1 or not? There only a few days left for code changes to land and be tested.

Ed, do you think this is going to be fixed for 33.1?

I believe clarkbw meant to remove this from blocking the anniversary and move to followup work.
