Bug 1428264 - Do not show chrome urls in storage inspector r=pbro On investigation it turns out that no storage types are supported for chrome:// urls. MozReview-Commit-ID: JZcQg5FvfvN

Bug 1447198 - Disable event emitter logging in DevTools. r=ochameau Disable event logging by default, particularly in workers, which can't read the pref normally used to control this. (The pref is already false by default, so this is only a behavior change in workers.) MozReview-Commit-ID: 8DGrpe0koSY

Bug 1446222 - Move DevTools worker startup to new dir. r=jdescottes Move and rename the server's worker debugger script that starts DevTools for a worker from `worker.js` to `startup/worker.js`. These code paths will likely change more as Site Isolation work continues, but for now, we have this light cleanup to gather startup-related paths together. MozReview-Commit-ID: EvzDSGnG1vU

Bug 1446222 - Move DevTools service worker control script to worker actor dir. r=jdescottes The `service-worker-child.js` process script is used by actors to control service workers as needed. This moves it to helper directory near the actors that make use of it. MozReview-Commit-ID: LIq1zcU6fBc

Bug 1446222 - Move DevTools content process startup to new dir. r=jdescottes Move and rename the server's process script (and accompanying JSM) that starts DevTools for an entire content process from `content-process-debugger-server.js` to `startup/content-process.js`. `connectToContent` also becomes the more specific `connectToContentProcess`. These code paths will likely change more as Site Isolation work continues, but for now, we have this light cleanup to gather startup-related paths together. MozReview-Commit-ID: 1evbZMB8T7r

Bug 1446222 - Move DevTools frame startup to new dir. r=jdescottes Move and rename the server's frame script that starts DevTools in remote frames from `child.js` to `startup/frame.js`. `connectToChild` also becomes the more generic `connectToFrame`. A few b2g-isms like "app" are also removed. These code paths will likely change more as Site Isolation work continues, but for now, we have this light cleanup to gather startup-related paths together. MozReview-Commit-ID: El8a0OE99gZ

Bug 1446222 - Move WebGL primitives to Canvas actor dir. r=jdescottes MozReview-Commit-ID: 8Zv7cJFFG88

Bug 1447345 - Change enterprise policy that sets homepage to set it as the default rather than the user value for the pref Additionally removes a stray debugging line that I accidentally checked into the tree previously. MozReview-Commit-ID: 7F2S8WBgKCj

Bug 1443443 - Extend PContent to retrieve Performance Counters in the parent process - r?baku Adds the IPDL layer to asynchronously retrieve in the parent process the performance counters. MozReview-Commit-ID: RbKstNx8pi

Bug 1444976 - Decide how many threads to use in the threadpool using the number of threads the machine can run. DO NOT LAND MozReview-Commit-ID: LlLCKjeJ6Ez

Bug 1444976 - Another type of logging to be converted later or maybe removed. MozReview-Commit-ID: LdKQZ4zagxV

Bug 1444976 - Trace some initial real-time media stuff. Tracing is very cheap, we should trace a bunch of stuff. MozReview-Commit-ID: IhOyyRPXfg9

Bug 1444976 - Use the AsyncLog to implement a tracing subsystem for real-time media. Use it like this: > MOZ_DISABLE_CONTENT_SANDBOX=1 MOZ_LOG=MSGTracing:5 MOZ_LOG_FILE=trace.log ./mach run After done, open `trace.log`, remove the junk that MOZ_LOG puts in front with something like `sed 's/.*MSGTracing //' trace.log.child-1`, and add a single `[` at the beginning of the file. Now open `chrome://tracing` and load the file. Lanes are threads, thread 0 is the audio callback thread, the other thread have normal numbers. Thread 1 shows the theoretical budget we have for a particular audio callback. MozReview-Commit-ID: 87woGiFT4ID

Bug 1444976 - Implement a lock-free asynchronous logging system to be used from real-time audio and video code. This outputs to MOZ_LOG and using an MPSC lock-free queue so we can log to a particular module from any thread. MozReview-Commit-ID: INtlki4PEJs

Bug 1444973 - Remove browser-test-overlay.xul. r?ahal On desktop use sub script loader during bootstrap instead of the overlay. On android use a component that listens for browser windows to be created and then use a sub script loader. MozReview-Commit-ID: Knj5OdVNEMA
