This bug is for tracking leaks and quasi-leaks reported against Firefox 6 (at any stage in the nightly/aurora/beta/release cycle). Bug 640452 was originally used for this purpose, but it has been decommissioned and this bug has been created as part of a new collection of per-version leak tracking bugs. Leaks reported against earlier versions that have been confirmed to still be present in this version can also be tracked here. Leak reports against this version that lack sufficiently specific information may be marked as duplicates of this tracking bug.
This tracking bug has reached the end of its useful life. All the still open blocking bugs have had their whiteboards marked with "MemShrink", and so will be tracked that way by the MemShrink project.
