This is an archived snapshot of W3C's public bugzilla bug tracker, decommissioned in April 2019. Please see the home page for more details.
Specification: http://www.whatwg.org/specs/web-apps/current-work/multipage/common-dom-interfaces.html Multipage: http://www.whatwg.org/C#htmlallcollection-0 Complete: http://www.whatwg.org/c#htmlallcollection-0 Referrer: http://www.whatwg.org/specs/web-apps/current-work/multipage/ Comment: Remove support for document.all.tags Posted from: 87.64.214.136 by ms2ger@gmail.com User agent: Mozilla/5.0 (X11; Linux x86_64; rv:23.0) Gecko/20130421 Firefox/23.0
Gecko hasn't has working support for it since Firefox 3.
Is anyone else planning on dropping it?
Tab, do I recall correctly that you were looking at this in Blink?
I haven't yet done so, but I can add a use tracker when I get back to my desk next week.

From blink-dev's "Intent to Deprecate and Remove: document.all." thread: We also have trackers for DocumentAllLegacyCall (0.00%) (using HTMLAllCollection as a function) and DocumentAllTags (0.00%). So can we nix both of those? ;) I believe Firefox right now supports the legacycaller but but not .tags.
From the Chromium bug cited in comment 5: We got 0.001% for our DocumentAllTags UseCounter. Conclusion: Safe to remove.
That's fantastic. Removed!
Checked in as WHATWG revision r8469. Check-in comment: Remove some parts of document.all that data shows have virtually no usage. http://html5.org/tools/web-apps-tracker?from=8468&to=8469
More from blink-dev: FWIW, this number is wrong. Looking at Chrome's latest stable release on Windows, DocumentAllLegacyCall is used on 0.03% of sites. We've still been figuring out what the lower bound is on features we can safely remove, so this is a useful data point that 0.03% is likely too high.
Reopening to track likely reversion of at least the legacycaller stuff. :-(
Checked in as WHATWG revision r8502. Check-in comment: Restore document.all() legacycaller, for compat http://html5.org/tools/web-apps-tracker?from=8501&to=8502
