Status: RESOLVED DUPLICATE of bug 1006102

(WebExtensions :: Developer Tools, defect)

Description

[Dave Vandyke]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:70.0) Gecko/20100101 Firefox/70.0

Steps to reproduce:

1. Install the LastPass and Adblock Plus Add-ons.
2. Browse to about:debugging#/runtime/this-firefox
3. Click the "Inspect" button next to Adblock Plus.
4. Switch to the console pane of the toolbox window which opens.
5. Type "lp" into the output filter.

Actual results:

A bunch of exceptions and warning relating to LastPass are listed:

Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user's experience. For more help http://xhr.spec.whatwg.org/ lpfulllib.js:1:35359

Expected results:

No exceptions/warnings relating to LastPass should be listed, since it's the background console for Adblock Plus.
