What level do you have the security slider set to in Tor Browser?
Does this problem occur every time XMLHttpRequest?
Can you provide a test case or point us to a web page where we can see this problem occur?

That's the sort of message NoScript produces when it blocks XHR based on its policy (whitelist and/or forbidXHR).

This is very likely not a bug.

Usually see that something is writing in Browser Console, but there are so many messages that it's hard to monitor them while surfing.
XHR EXC was seen rarely.
Most common messages are:

TelemetryStopwatch: key "PLACES_AUTOCOMPLETE_URLINLINE_DOMAIN_QUERY_TIME_MS" was already initialized TelemetryStopwatch.jsm:52:0

[Exception... "Component returned failure code: 0x80004002 (NS_NOINTERFACE) [nsIWebProgress.DOMWindow]" nsresult: "0x80004002 (NS_NOINTERFACE)" location: "JS frame :: chrome://browser/content/browser.js :: TabsProgressListener.onStateChange :: line 15052" data: no]

After the latest update:
