Attached file Test extension (obsolete) —
Steps to reproduce:

* Go to about:debugging and load the attached extension as a temporary extension.
* Go to about:addons, find "WebExtensions test" in the list and click its "Preferences" button.
* Press Ctrl/Cmd+Shift+J to open Browser Console, have a look at the messages.

Expected results:

Both "ping" and "pong" are listed in the Browser Console - the options page sent a message to the background page and received a response back. That's the behavior I see in Firefox 54 and Chrome 59.

Actual results:

Only "ping" is listed in the Browser Console, the response hasn't been received by the options page - tested with Firefox 56.0a1 nightly (2017-07-11) on Ubuntu. This affects both communication via plain messages and ports. I'm fairly certain that it used to work only a few days ago, so a pretty recent regression.

My bad, not sure what went wrong with my testing. This seems to affect port-based communication only, which is what I was doing initially. I replaced the test extension by one using ports to communicate and verified that the issue is reproducible with a clean profile on Firefox 56.0a1 nightly (2017-07-12) on Ubuntu.

Strange, extensions.webextensions.remote isn't the default on Linux and was indeed off for me. Which doesn't mean of course that it isn't a side-effect of one of those changes.

I was able to reproduce the initial issue on Firefox 56.0a1 (2017-07-09) under Windows 10 64-bit.
Verified as fixed on Firefox 56.0a1 (2017-08-01) and Firefox 57.0a1 (2017-08-02) under Windows 10 64-bit and Ubuntu 16.04 32-bit. Both "ping" and "pong" are listed in the Browser Console.
I forgot to retest this issue. In Firefox 57.0a1 (2017-08-02) on Ubuntu everything seems to be working as well, Easy Passwords 1.2.1 options are working - it has been released as a Web Extension in the meantime.
