URL: https://www.outlook.com
Browser / Version: Firefox 42.0
Operating System: Windows 7
Problem type: Something else - I'll add details below

Steps to Reproduce
1) Navigate to: https://www.outlook.com & log into the email account.
2) There's a bunch of smooth animation when you click on different item on the email pages with Opera but none when you choose Firefox as the browser.
Even though there are a couple of animated elements the transitions are not smooth and often appear clunky.

Expected Behavior:
Equal browsing experience of Firefox just like Opera. Smooth Transitions and Animations.

Actual Behavior:
Clunky non smooth animations/transitions OR no animations on Firefox while everything is enabled on Opera.

@hallvors do you have an Outlook test account (or otherwise) to investigate?
@bull500 sorry for taking so long to get to this, is the perf just as bad in 46? And in Nightly?

@miketaylr
The animation thing still exists. I tried reaching out to Outlook team via their feedback and as usual falls on deaf ears.
I hope someone can contact outlook on this inconsistency.

Funny thing is i'm noticing sites which use transitions- they don't work good on Firefox

This is NatGeo site with a slide show i found for bug no. 1268237 - http://news.nationalgeographic.com/2016/04/160425-new-delhi-most-polluted-city-matthieu-paley/
Here as well the same problem; the the slide in/out transitions are much less consistent. Some slide and appear in and others just flash appear

Also attaching a video to show the Outlook problem.
I think there might be other animation things on that site, but i don't remember now sorry :(

Tested with Nightly49

I have an old Hotmail account which now loads an Outlook-branded UI. I assume I'll be able to test this :)

[hallvors]

I confirm that the Outlook UI feels sluggish in Firefox now. It looks fine (they're emulating Google's "Paper" style it seems) but feels a little unresponsive. (Given that this is on a fast computer and an account with a minimal amount of E-mail and data I suppose it can get a lot worse).
I don't know yet if this needs optimising in Gecko or in Outlook - I assume the former though. Perhaps we should move it to Bugzilla. It also needs some profiling..

[miketaylr]

I know there's work going on right now to work on janky animations (I'll try to find the right bug).

@hallvors if you can do some more investigation or profiling, that would be good. Feel free to close here and link to a Bugizilla bug if you open one.

(also, thanks @bull500)

@miketaylr janky animations is one thing like the NatGeo example.
But it feels/seems like Outlook doesn't even provide the main ones to Firefox

[hallvors]

Re-testing this today, doesn't feel as janky as last time. I agree that they seem to use transitions less in Firefox - whether that's by accident because they use some webkit syntax (testing in release version without any webkit prefix hacks) or on purpose to avoid performance issues, I don't know. Also interesting that if I create a new message it's launched in a popup, not in an inline editor like in @bull500 's video.

[hallvors]

I found the setting for showing the editor inline. Profiling data in Nightly of creating and discarding a new E-mail is here: http://hallvord.com/temp/moz/profile-wc1751.json
It feels a little janky, but not too bad. I've tried to use it a bit more like regular usage and less "testing".

IMHO this is not outreach "material" right now. I'll instead report a bugzilla bug on doing more performance testing against Outlook.com.

This exists already: https://bugzilla.mozilla.org/show_bug.cgi?id=1275000 - good

Thanks for the bug listing @hallvors :smile:
