Steps to reproduce:
I create web extensions with background script
and load it as a temporary extension into clean profile via the debug extensions page. I do see
foo in the console, however alert is not shown (based on https://bugzilla.mozilla.org/show_bug.cgi?id=1203394 I've believed the
test string would show up).
But what is worse, the extensions seems to be now stuck. When I modify the background script to
reload, still only the
foo is visible, so the extension is not reloaded. And when I try to turn off firefox (via exit in the menu), windows closes and developer console stays open. After I close that as well, I still see firefox as running in task manager and need to ctrl+c it from terminal to actually terminate.
Extension (and firefox) is kinda stuck after alert() in background script.
