Currently I'm looking at about:memory like this:

I don't think the sha1 are very useful unless I can link them to origins in about:memory.

It would nice to know which domain the blobs are coming from.

The leak itself might be bug 1272078

Comment 2

[Eric Rahm [:erahm]]

kanru, are you still seeing this after bug 1272078 landed?

Looks like the leak is gone. I can't find any memory-file-data in about:memory anymore.

It can be a side effect of the IPCBlob refactoring.
