In the process of fixing bug 1241298, I noticed that the memory panel does not work with addon debugging. The panel is blank and the tool never loads. Can't figure out how to get at a console for chrome code in the addon debugger process, so I couldn't find out if there was any obvious error messages either. In the meantime, we should disable the memory panel for addon debugging.

It looks working for purely-WebExtensions, change https://hg.mozilla.org/mozilla-central/rev/b9d5aa8be125#l1.13 to isWebExtension()?

Is there a way to write a sanity test? If you want to submit a patch, Greg Tatum would be a great reviewer! I'm not actively working on the devtools anymore, personally.

Anyone can find someone to deal this issue? I guess the panel will works for WebExtensions.

Sorry, I'll probably only fix regressions on the memory panel for right now as I'm focused on profiler work.
