Here's the profile that hallvors originally gathered: https://cleopatra.io/#report=ec6ca9e148231495653c86f20d1a1cb4f7037822&selection=0,1,29,3,93,94,95,96,97,98,99

Hey hallvors, is it possible to get another profile but using the Gecko Profiler add-on instead of the DevTools profiler?

A lot of the DevTools instrumentation is showing up in the profile and is adding a bit of noise. I imagine that's often filtered out when profiling an individual page, but when viewing it in Cleopatra, it distracts.

One thing I _have_ noticed looking at this profile is that there are some sync IPC messages being sent from content to the parent to query the dimensions of the screen that it's on. These sync messages, if they occur during an animation, would certainly cause a stutter (I'm seeing an instance of 172ms of waiting for that sync IPC message to complete, for example).

Making those screen dimension IPC queries non-synchronous is being tracked in bug 1194751.
Profile #1: this is just re-loading the main UI (this doesn't really feel slow though)

Profile #2: creating a new E-mail, discarding it again (this feels a little laggy):

Profile #3 - I've forgotten:

Profile #4 - click "trash", select all (10) visible items with the checkbox in the header, click "Move" and select inbox:

Using the Outlook.com UI with my (lightly used) old Hotmail account does not feel that slow to me. In the webcompat issue it was mentioned that the site may be disabling certain transitions and animations to speed itself up in Firefox.

Note: This test and results is for Office 365's Outlook and not Exchange Outlook Web App (OWA) which most problems are reported against. We should either change the title of the bug to remove the 'Exchange' piece or we should open something new for testing against Exchange versions of OWA. 

The challenge with the latter is the setup of different Exchange setups and versions.
