Can I get a regression-range hg link?

Crashes show up discontinuously in nightlies. In addition, it is a residual crash signature that exists also in 3.6.

The only comment says: "Hi, I do not know why but the wolf time I open FF I get just up the Mozilla crash reporter / Do not install the browser before I extracted my bookmarks. What can I do?"

Its ranking as a top crasher is above 300.

The signature for ScanPluginsDirectory changed, but this crash still occurs with lowish volume

Resolving old bugs which are likely not relevant any more, since NPAPI plugins are deprecated.
