WebRTC sharing indicator displays an XML parsing error
Surely your lovely Firefox browser started throwing an annoying yellow window like this one
XML Parsing Error: no root element found
Location: chrome://browser/content/webrtcLegacyIndicator.xhtml
Line Number: 1, Column 1:
^
This is a very ooold Firefox bug that returns from the bottom of the sea from time to time. Som people reports that the error is does not appear when privacy.webrtc.legacyGlobalIndicator is set to false in about:config
Others report that going to about:support, click the “Clear startup cache…” button on the top right, and then restart Firefox solved the issues for them
In case you want to help to fix it would be helpful if you could go to about:telemetry, search for ysod and share what you’re seeing there (screenshot, or copy-paste the table data, if it’s not empty) and drop a note into the bug
