Hi everyone,

I just wanted to make a quick announcement about preference changes for 
out-of-process tabs. Bug 960783, which landed recently, added a "New OOP 
Window" menu option to open a new window with out-of-process tabs. Right now 
this option is only enabled on Macs because it requires OMTC, but it will move 
to other platforms as they get OMTC. It's also restricted to nightly.

This change required some reinterpretation of the existing browser.tabs.remote 
preference. We use this pref in a fair number of places, so I want to make sure 
that everyone understands how it works now. This is the new setup:

If browser.tabs.remote = false, then remote (i.e., out of process) tabs are 
completely inaccessible. This is how we'll keep this feature disabled in 
non-nightly builds.

If browser.tabs.remote = true and browser.tabs.remote.autostart = false, then 
browser windows will normally be in-process. However, the user will see a new 
menu option, "New OOP Window" that will open a window with remote tabs. This 
configuration is now the default in nightly on Macs. For non-OMTC platforms, 
browser.tabs.remote=false will remain the default.

If browser.tabs.remote = true and browser.tabs.remote.autostart = true, then 
browser windows will normally have remote tabs. However, the user will see a 
new menu option, "New In-process Window" that will open a window with 
in-process tabs. This configuration is for people who want to test e10s more 
extensively.

We're hoping that exposing the "New OOP Window" menu item will make it easier 
for people to test electrolysis.

-Bill
