I don't think we should spend time on making that work. The "open new e10s window" is just a nice feature to kick off doogfooding better but if you really want your tabs restored as "remote" you should probably just be running in e10s mode.

I agree. This is the behavior we expect.

Thanks for the report though! They're always appreciated :-).

FWIW I like running in mix mode and this annoys me when doing manual testing. My workflow looks like this:
- Close browser with e10s with my test case
- Edit, recompile, run
- Non e10s tab running my test case is restored
- Sometimes accidentally test with my test case while I forget it's no longer running remote.
- Close my testcase running without e10s
- Open e10s window manually (no shortcut key)
- Go to test case

If you're testing a lot with e10s, I would recommend doing it in a profile where browser.tabs.remote.autostart is set. That way, all your tabs will be restored as remote. It's also more convenient not to have to ask for an e10s window in the first place.

Thanks for the tip, I'll try that. But I still feel like this would promote nightly users testing e10s more.
