Is there any way to simulate a extension env on web?
If your problem is happening in an extension, then filing a bug
and attaching a testcase add-on is your best bet.
If I had to guess based on what you've told us so far, I'd say
your problem has something to do with X-ray security
wrappers[1]. In general, properties that you add to X-ray
wrappers aren't visible to code running in other globals. I.e.,
if you're accessing a web page from an SDK content script, your
view of the DOM nodes are different from the view the web page
sees. This also has implications for properties that you add to
prototypes.
I don't know of any changes that would have significantly
changed the behavior in 45 vs previous versions, though, so a
testcase would be useful.
