User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:18.0) Gecko/20100101 Firefox/18.0 Build ID: 20130201065344 Steps to reproduce: Test page: http://www.snappymaria.com/misc/svg-id-test/ On this page, click the "Open as Blob..." button to see a test of SVG elements rendered inside of a Blob. The SVG references to its own "defs" element do not work inside of a Blob. Actual results: SVG references, which work on a normal HTML page, do not work inside of a Blob. Expected results: SVG references should work in Blobs.

Good news! This seems to have been fixed on trunk recently. I'm tracking down an exact fix range, but I suspect it was fixed by bug 1280584.
Yup, "mozregression --find-fix" confirms that this was fixed by bug 1280584. (And indeed, that bug seems to be about basically the same issue, except with about-URIs instead of blob-URIs. And it doesn't look like the fix there was specific to the "about:" protocol -- it was general rewriting of some URI stuff across URI implementations.) --> Duping to that bug.

Along with testing Nightly, I verified locally that this is fixed in the latest DevEdition build (version 50.0a2 (2016-08-10)), BTW. (As you'd expect, since bug 1280584 landed in the version-50 timeframe.)
Depends on: 1447262
This has regressed -- the regression is tracked in bug 1447262. Also worth noting, for the record: if you happen to have uBlock Origin installed, you'll need to disable it in order for the testcase here ( http://www.snappymaria.com/misc/svg-id-test/ ) to function. When you click "Open as Blob...", uBlock origin blocks the new tab as a popup, via a filter labeled "|blob:$popup" in EasyList.
