All extensions or a special one ?
This bug report looks invalid (extension which is using unfrozen interfaces is used)

Comment 2

[Richard Aspden]

Several attempted from u.m.o - doesn't seem to be specific to one extension.
This is on a clean profile too.

Comment 3

[Matthias Versen [:Matti]]

could be bug 282858

Comment 4

[Richard Aspden]

Could be related, although they were throwing JS errors, and this was a physical
dialogue box before getting the main browser window.

Comment 5

[Richard Aspden]

Another thing to note: it only happens the first time it's reloaded with the
extension install, which seems to suggest there's something wrong in the install
mechanism itself. That does point to a possible follow-up issue to bug 282858.

Which extensions, in particular, are involved? This sounds like a typical error
where extensions built against an older version of XPCOM are used with the newer
xpcom_core and NS_Alloc functions.

Looks like you're right. Newer builds of extensions don't seem to have the
issue. Sorry, should have spotted that.
