At the Testing It Out (https://developer.mozilla.org/en-US/Add-ons/WebExtensions/Your_first_WebExtension#Testing_it_out) stage, I followed the instructions to: - open about:debugging - click on the Load Temporary Add-On button - select a file from the add-on's folder - click Open Actual results: Dialog for choosing files was dismissed but the add-on wasn't loaded at all, no visual feedback at all, the list of add-ons remained the same. Expected results: Add-on should have been added to the list, and loaded into the browser.

Hi Gem, thanks a lot for reporting this bug! Maybe there was an error when you tried to load your temporary add-on in Firefox, but about:debugging didn't show it. I see from your submission details that you're using Firefox 47. In Firefox 48, we fixed bug 1231128, which was preventing load-time errors from showing up. Could you please try reproducing the problem in a more recent version of Firefox, e.g. Nightly? Andrew, is it possible that Gem's error would be caught and displayed in about:debugging now that bug 1231128 is fixed? In that case maybe we could close it as a duplicate.
Yes, this sounds like exactly the scenario that bug 1231128 is meant to address. Agreed that it is probably a duplicate, please try on 48 or newer.
Just tested on Nightly and it seems to be fixed. Thanks for looking at it though. Closing.
