Electrolysis and privileged content: JS Modules, XPCOM Services, XBL etc.

[Fruitbalad]

Hello,

Reading the Electrolysis wikipage, this newsgroup seems to be the
appropriate place for questions about Electrolysis ...

I developed a firefox extension that adds filebrowser capabilities to
firefox. browser-tabs are used to display the fileviews (chrome-
url's), which are privileged code. the code is currently heavily
relying on js modules

Now that every tab is going to have it's one process due to the
electrolysis-project (someday), I wonder what happens with JS Modules
and XPCOM-Services. Are those still shared across the whole
application in some way or will every process have its own instance?
Same goes for XBL-bindings - will those also be compiled per process?

Will cross-process-communication only be happening via message-
passing?

Thanks.

Then those should be loaded in in-process tabs, I would think.

That's not the plan. The plan is to have a pool of processes used for
tabs showing web pages (so multiple tabs can all be in the same process,
in fact). In-tab browser UI (e.g. about:addons) would continue to be in
the browser process.

The latter, but that's not really relevant to your use case.

Yes.

From an API standpoint, I believe the answer is yes (though under the
hood there may be shared memory or whatnot involved). But don't quote
me on this. ;)
