reproduced using keyboard shortcuts (at all steps except the error console step)

this problem sometimes occurs when the preferences window is not opened (step 6 is skipped), but always occurs when step 6 is done.


if preferences window is not opened, the error shown is:

Leaked outer window 16c14840 at address 16c14840.
Leaked inner window 1e96b6f0 (outer 54d900) at address 1e96b6f0.
 ... with URI "about:blank".
Leaked outer window 54d900 at address 54d900.
Leaked inner window 1dcd1a0 (outer 16c14840) at address 1dcd1a0.
 ... with URI "chrome://browser/content/hiddenWindow.xul".

Summary:
Leaked 4 out of 15 DOM Windows
Leaked 0 out of 52 documents
Leaked 0 out of 7 docshells

I'm not seeing this. What extensions are installed?

fresh profile. the keyboard shortcuts situation apparently is erratic; sometimes it works properly (no leakage) other times it still leaks.

Mouse-clicking definitely still leaks.

shifting back to error console reveals:

"Error: [Exception... "'Component does not have requested interface' when calling method: [nsIInterfaceRequestor::getInterface]"  nsresult: "0x80004002 (NS_NOINTERFACE)"  location: "<unknown>"  data: no]"

after pressing the organise bookmarks option at step 4. Might this be related?

(can't seem to reproduce the leaking anymore)
