I can open two separate toolboxes for two addons, so I am not able to reproduce the original problem.
But, I am seeing an issue with concurrent stepping

STR:

  1. Clone this addon: https://github.com/firefox-devtools/har-export-trigger Clone it twice on your machine and change the ID in the manifest.json file, so you have two different addons
  2. Use about:debugging#/runtime/this-firefox to load both of them as separate addons
  3. Click the Inspect button for both these addons to open two separate toolboxes (I am moving them into two separate browser windows, so it's easier to follow what's happening)
  4. Select Debugger panel and create BP in devtools.js file in onMessage function - again for both of them
  5. Load this page: http://janodvarko.cz/test/harexporttrigger/ open content DevTools Toolbox on it and click on getHar button (at the bottom of the page)
  6. Both breakpoints created in step #4 should hit
  7. I can step in the first addon toolbox just fine (try just once, so the execution is still stopped), but stepping over in the second toolbox doesn't work properly. After first step over, the execution/debug line disappears. But the debugger is still in paused mode

Note that after resuming both and clicking on getHar buttton again the breakpoint in the first addon toolbox doesn't hit at all.

If I resume the first toolbox the stepping works fine in the second toolbox.

Could this be related to run-to-completion?

Honza, I tried this out, but I couldn't find the devtools.js source file in the debugger. Is there something I'm missing?

The devtools.js file comes from the extension, see the attached screenshot.

I can still reproduce the problem on my machine.

(Lovely. I can bugzilla.)

In any case, we have something interesting to look into here.

Sorry, there was a problem with the detection of inactive users. I'm reverting the change.
