Hey, i see this error when clicking the adoon, on any website:

"Cannot operate on this page (Script '' result is non-structured-clonable data)"

Any idea?

useless, just login for to share my bad experience with this addon :(

Could not get cookie-editing working, did not import cookies from my site. Ended up editing directly in firefox's storage-pane

It does not allow to import cookie in text format as in Chrome.

This extension is useless as long as there is no delete all cookies for current domain.
