Status: RESOLVED FIXED

(Core :: DOM: Core & HTML, defect)

AFAICT it always returns true, but nobody actually calls either the XPIDL or webidl implementations anywhere, so we're just shipping dead stuff. I found exactly 1 add-on "using" this read-only prop:

https://addons.mozilla.org/en-US/firefox/addon/browse-images/ - but afaict that function gets called in exactly 1 circumstance, namely if the image width and height are both exactly 24 pixels. That seems like buggy code - I don't think that justifies keeping our dead bits around.

Edgar, this seems in your wheelhouse :)

Hi Olli, I am willing to take this bug to remove ImageDocument.imageResizingEnabled, but it might cause add-on compatibility problems, although there seems only one add-on using this prop. How do we usually deal with this situation?

[Olli Pettay [:smaug][[e-mail]]]

jorge could answer to that.

Is the addon which is using this updated recently? Is it compatible with current FF release?

[Olli Pettay [:smaug][[e-mail]]]

I think you could also just contact the addon author and ask whether it is ok to remove the property.

[Jorge Villalobos [:jorgev] (he/him)]

It's a very old add-on, probably abandoned. I'll include this in the compat communication, but the impact is minimal, so please go ahead with it.
