Describe the bug
The project https://github.com/engageLively/galyleo-dashboard loads in Microsoft Edge and Google Chrome, but not in Firefox. The console error message is:

this.window.gBrowserInit is undefined [ext-browser.js:1148:9](chrome://browser/content/parent/ext-browser.js)
    get activeTab chrome://browser/content/parent/ext-browser.js:1148

It gets past the dependency status dialog before it fails, and it does pop up a box saying that we're using the latest version of lively
Firefox version 137.0.2

A quick google search leads me to believe this is a Firefox bug that has got something to do with ad blockers: https://bugzilla.mozilla.org/show_bug.cgi?id=1634240
None of the modules involved here appear to be related to lively.next.

For me, the workaround is pretty easy -- I just use Chrome or Edge. @merryman You can close or leave open, up to you...
