The CSSWG resolved to remove "box-sizing: padding-box",  so we're removing support for it as well, as discussed in bug 1166728.

Filing this bug to track evangelism for fixing up addons code that uses "box-sizing:padding-box.

(Authors should instead use "content-box" or "border-box", depending on whether or not they want sizes to include border/padding. They have to include both border+padding, or neither. In most cases, "border-box" is probably appropriate, since content-box is the default.)

bz posted this addons MXR search query to help with discovering addons that need fixing:
https://mxr.mozilla.org/addons/search?string=box-sizing%3A+padding-box&find=&findi=&filter=^[^\0]*%24&hitlimit=&tree=addons
Summary: Remove "box-sizing: padding-box" from addons → Reach out to add-on authors to get them to remove now-invalid CSS "box-sizing: padding-box"

Using the addon-compat keyword in the original bug and setting the right milestone when it lands is sufficient. We do outreach for every release and don't track it through Bugzilla.

Thanks for the heads-up!
