Created attachment 801084 [details] [diff] [review] bug913756 v0 In the release version of FF we recognize an "after-viewport-change" message but fail in _updateCacheForSelection() processing due to: 1) The assumption that there's a valid selection still and we just need to update the handle position 2) selection.getRangeAt(0) == null, something the code doesn't expect. The routine logs an |Exception... "Index or size is negative or greater than the allowed amount"| message, fails, and the handles are left hanging with SelectionHandler in status TYPE_SELECTION. This situation also occurs in Nightly, but due to our recent improvements in this area involving the addition of the notifySelectionChanged() routine, we recognize and attempt to address the loss of the selection, but need one tweak to the shutdown code _clearSelection() to correctly solve the rangeCount == 0 problem.

Comment on attachment 801084 [details] [diff] [review] bug913756 v0 Review of attachment 801084 [details] [diff] [review]: ----------------------------------------------------------------- Nice catch. Just to double check, the improvements that exposed this issue are just on Nightly, not Aurora, right?

Recent improvements came through bug 864589 bug 903316 bug 907271 bug 908861 ... (I think that's all the relevant pre-reqs here though we recently also pushed bug 903871 and 906499). Yes, all of these changes are in nightly, and no, none seem to be in my (now) current aurora repo.
