Open Firefox Developer Edition. Set about:config flag 'xpinstall.signatures.required' to false. Click the 'Load Temporary Add-on' button on about:debugging. Select the manifest.json file you created earlier. Actual results: The file selection window disappeared. That's it. Nothing else happened. Expected results: An error or popup (or something in the console) saying that Firefox only supports manifest_version 2 at this time.

I see it in Fx47.0a2 (2016-03-20), but WFM in 48.0a1 (2016-04-09) on Win10, a warning say: There was an error during installation: Extension is invalid. Fixed in bug 1231128.

Hi cliabhach, welcome to Bugzilla! Thanks a lot for taking the time to log this bug. Your problem looks similar to bug 1231128, which was fixed recently, and adds an error message to about:debugging when 'Load Temporary Add-on' fails. The fix landed in Firefox Nightly last week, so it will be available in the next Firefox Developer Edition, which releases in about 3 weeks from now.
Wow, sorry, I completely missed that one. Figures that my first bug report is a duplicate....

Don't worry about it, it's better to file so the issue gets logged at least! :) It's easy to miss duplicate issues, and the team working on a component should be able to spot them quickly.
