1524600 - Errors in browser console when enabling CSS errors in the filter

Status: RESOLVED DUPLICATE of bug 1523020

(DevTools :: Console, defect)

Description

[:Gijs (he/him)]

STR:

1. clean profile on nightly/beta/release (I tested on mac, but I'd be surprised if it were machine dependent)
2. open browser console
3. click filter button
4. enable CSS errors

ER:
it works

AR:
errors:

Stylesheets without CSSOM changes reparsed to check for errors. Refresh the page to also see errors from stylesheets changed from CSSOM and from style attributes.

uncaught exception: Protocol error (unknownError): Argument 1 of InspectorUtils.getAllStyleSheets is not an object.

This has been happening since at least 65. :-(

Thanks for filing Gijs, I'm going to mark this one as dupe of Bug 1523020.
