384336 - Firefox window should start up maximized on first run on small screens

Status: VERIFIED FIXED

(Firefox :: General, defect)

Description

[Martijn Wargers (dead)]

Most of my programs I only use maximized. Firefox is no exception, I think it should start up maximized on first start or on a new profile.
It saves me from having to do that myself.

Comment 1

[Simon Bünzli]

Platform standard for Windows seems to be to start non-maximized - I've in fact never seen a program which would per default claim all screen space for itself.

Besides, with increasing screen resolutions, people are less likely to run any app maximized - since that usually just leads to more blank/unused space.

I'd rather vote for Firefox starting up in the platform's default size and position for new windows (Windows gives you those when you don't specify initial dimensions / location).

Comment 2

[Martijn Wargers (dead)]

I have a 1440*900 monitor here, but I still have most programs maximized.
Not sure how you found out that the platform standard for Windows is starting non-maximized.
What is the default size and position in windows? Where can I find that out?

Comment 3

> how you found out that the platform standard for Windows

Simply by trying out clean installations of a whole lot of different programs. None of them started maximized. So we wouldn't want to surprise new users by suddenly "hiding their desktop".

> What is the default size and position in windows?

As I said: those depend - among others - on the current screen dimensions. Windows will itself place your window correctly if you pass it the CW_USEDEFAULT flag for window size and position when creating the window (cf. http://msdn2.microsoft.com/en-us/library/ms632679.aspx ).

Comment 4

[Simon Bünzli]

Seems that I haven't tested well enough... correcting myself: Opera 9, Acrobat Reader (5 probably later versions as well), and most Microsoft Office 2003 applications default to opening maximized at my screen resolution (1024 x 768).

Comment 5

[Martijn Wargers (dead)]

Thanks for testing!
I also did some testing now.
Adobe Reader 8.1 doesn't start up maximised.
Open Office 2.2 doesn't start up maximised.
I was testing with a 1280*1024 resolution.

Comment 6

[Chris More [:cmore]]

Ok, after 8 years, I totally got this bug. We need to just make this happen asap as we have data that shows screen resolution is negatively impacting conversion rates of the Firefox Accounts sign up flow on /firstrun/. Firefox Accounts is relatively new to /firstrun/ so there wasn't much of an issue before, but now that accounts is central to the cross-device platform, there is now emphasis on this bug.

Why the asap nature? Because users who sign up for Firefox sync (even on a single device), are being retained much longer than people who don't. Also, this is a fairly simple patch and we just should do it. If it is low risk, we should also consider uplifting to take advantage of the better UX on /firstrun/ with a larger screen without other distractions.

The last time the default size on an new profile was touched was in bug 719318.

The logic is:

// Very small: maximize the window

Logic: <= 600px width

Percentage: near 0% of /firstrun/ users

// Portrait  : use about full width and 3/4 height, to view entire pages

Logic: width < height

Percentage: < 0.01%

// Widescreen: use about half width, to suggest side-by-side page view

Logic: >= 2048px width

Percentage: < 0.6% of /firstrun/ users

// Otherwise : use 3/4 height and width

Logic: catch-all else

Percentage: 99%

---- 

Given the information above, let's focus on improving the UX for 99% of our new users.

Code is here: http://mxr.mozilla.org/mozilla-central/source/browser/base/content/browser.js#1027

I am going to suggest we take out the * .75 for the else condition:

1052           defaultWidth = screen.availWidth;
1053           defaultHeight = screen.availHeight;

This will keep the /firstrun/ page maximized for 99% of users and keeps the edge cases in place for super wide screen, super small, and portrait screens to handle <=1% of users.

Comment 7

[Chris More [:cmore]]

dolske/mattN: This is a bug that we decided together in the onboarding summit that we should just do. I also just talked about with Matt and I realized this is a really old bug (request) and that we finally have evidence that the smaller screen is negatively impacting the UX on /firstrun/. Looks to be a simple patch.

Can one of you help?

Comment 8

[Justin Dolske [:Dolske]]

The code is easy to change, and there's nothing sacred about the current logic (in fact I would say the opposite ;), but I don't think it's quite as trivial as just using the max available width/height.

If we want to fill the screen, the window should probably just be placed in maximized mode. We'll still need to figure out an appropriate size for when it's returned to normal mode, and (modern) OS X is special in that it really only has full-screen and normal modes... A screen-filling window seems awkward there. 

I'd actually be very curious about what window size (and mode) users settle on after they've actively been using the browser for a while. I don't see anything in Telemetry to use, but since it's basically information exposed to web content this could be something we gather from a common page (whatsnew / download page)... Is there a sweet spot (in percentage of width/height) that users prefer, or correlation between small screens and maximizing? My browser happens to be 87% of the screen width and 97% of the (available) height, but I've no idea if that's normalish.

That said, feels like the most obvious win here would would be to at least just increase the percentage of the most-constrained dimension (height, on landscape displays). And in general I think we should err on the side of being bigger -- the user is probably going to tweak the window size anyway, so let's at least make sure it doesn't feel cramped and hide content on the very first page we load.


Aside: if firstrun conversion is important, the current page should be made responsive. It's currently a large, static page. So even if we maximize the window, it's still going to scroll on some displays. Anything under full-height on my 15" MBP is too small for that page. There's a huge amount of empty space at the top, which makes this all the more egregious. Changing the initial browser window size is really solving the wrong problem (and something we can only do because we're the browser vendor!). But this is all a bit moot, because I would still agree that the initial window isn't well-sized.


I was also going to mention revisiting the Linux sizing hack, but that has since been limited to GTK2. Probably worth double-checking that we're _actually_ getting the right values for GTK3 (which is now the default, and so this can just be removed).

1058 #if MOZ_WIDGET_GTK == 2
1059         // On X, we're not currently able to account for the size of the window
1060         // border.  Use 28px as a guess (titlebar + bottom window border)
1061         defaultHeight -= 28;
1062 #endif


Dao, can you take this as part of the Windows QX work? And Philipp may have further thoughts.

[(Currently slow to respond) Philipp Sackl [:phlsa] (Firefox UX) please use needinfo]

Sounds good!
80% of window width or height seem to be a good choice.

Good insights, Justin!

(In reply to Philipp Sackl [:phlsa] (Firefox UX) please use needinfo from comment #9)
> Sounds good!
> 80% of window width or height seem to be a good choice.

So, we are going to change it from 75% of the width/height to 80% width/height? Not sure if 5% change is even worth doing this bug.

What about if we just set it on Windows to maximize mode and keep it 75% width/height if they unmaximize it? Does that work? That way we don't have to really mess with any percentages and just set it to maximize on Windows and leave everyone else alone.

We are going to work on making the /firstrun/ page be responsive down to smaller resolutions. The original design created wanted the content to be side-by-side, but I am pushing for a slimmer responsive page. Actually, I am pitching it today.

Thoughts?

Comment 11

[Verdi [:verdi] Best to slack me]

How about something like this:
 ≤ 1280px width --> 100% width
 > 1280px width --> 1280px width
 ≤ 1040px available height (window height- taskbar or window height - dock+menu bar) --> 100% height
 > 1040px available height --> 1040px height

If it's Windows and the rule would result in 100% height & width then use maximized mode instead. We shouldn't use maximized on Mac since it's now full screen which seems to be a whole other thing.

The result is something like this - https://www.dropbox.com/s/1lmy52cxcsa0qeq/screen-sizes.png?dl=0

FYI this isn't really true, the green button now does fullscreen but the "zoom" option, the OS X equivalent of maximize, is still in the "Window" menu of most applications, including Firefox.

Comment 13

[Dão Gottwald [:dao]]

Attachment: WIP patch

This implements comment 11, mostly. I used 90% of the width / height since unmaximized windows that take up all the width or height seem potentially harmful (unless the user explicitly made it so). I think it's more user-friendly to leave some space around the window so it can be moved around, the user can glance at what's behind the window, etc.. As per comment 12, I haven't implemented any exception for OS X.

This patch causes a failure in test_set_window_size.py's test_that_we_can_get_and_set_window_size: "UnsupportedOperationException: Invalid requested size, cannot maximize"
I don't understand this yet, it doesn't seem to make sense at first glance.

90% is awkward on something like a 1024px wide screen, leading to sideways scrolling on many websites. Here's another idea that avoids maximized windows altogether, leaving a small 10px buffer around the Firefox window:

 ≤ 1280px width --> 100% width - 20px
 > 1280px width --> 1280px width - 20px
 Available height (window height- taskbar or window height - dock+menu bar) --> 100% height - 20px

Place the window 10px down from the top and 10px in from the left.

The result looks like this https://www.dropbox.com/s/fzz44ulunm23m44/screen-sizes2.jpg?dl=0

No, we'd maximize the window on a 1024px wide screen. The 90% is what you'd get when explicitly unmaximizing it.

David, any idea what could be going on here? With my patch, the window's size is 1616*1176 when the test starts. I have no idea how that could be a problem.

Comment 18

[Dão Gottwald [:dao]]

The test tries to resize the window to 1500*1060, which should work just fine...

Comment 19

[David Burns :automatedtester]

We ask Gecko what size the screen is that we can maximise and then if the values passed in are bigger than that we throw this error.

Right, but the size the test wants to use, 1500*1060, is based on subtracting 100 from screen.availWidth and screen.availHeight. So how can this fail the driver.js check that also uses screen.availWidth and screen.availHeight?

I don't know what to say, perhaps windows is lying to Gecko or there is some kinda of race condition?

Per our conversation yesterday, can we do this to avoid an awkwardly sized window on a 1024x768 screen?

If the screen is ≤ 1024 x 768 make the unmaximized size:
 * Width: 100% width - 30px
 * Height: Available height (window height- taskbar or window height - dock+menu bar) - 30px
 * Place the window 15px down from the top and 15px in from the left.

Hi Dão, I don't work on marionette anymore (I'm on a different team now) so I'm pretty rusty at this... I had a quick look at your patch and the test but I don't see anything obvious though, sorry. Good luck!

*Sigh* ... anybody else feeling responsible for this test? jgriffin, bug 1207899's reviewer maybe? I'm fairly confident that my patch is fine, and the earlier reported intermittent failure suggests that there's indeed a flaw in the test, maybe a race condition. I'm afraid this will burn a lot of my time if I dig deeper, so if nobody else cares I think I'll just disable the test and move on. :/

I did that in this patch, but I think it looks cramped and overall worse than using 90% of the width and height. I'll attach screenshots.

This is green on Windows. I suspect what the test couldn't handle with the older patch was that the window was maximized when the test started. This means the test will still have issues when running on a system with a screen size small enough that we'd maximize the window by default.

Here are the same window settings with the pages open on first run along with the bookmarks toolbar and data choices toolbar displayed. https://www.dropbox.com/s/7ldw4la16mo3a2f/comparisons.jpg?dl=0

I think, if we can do the larger window, it's better on this size screen.

I'm not sure we want to center vertically since we lose the benefits of Fitts' law on non-OS X (IIRC it default to the top before) and on OS X I personally like all large windows against the titlebar (Not sure what other people prefer).

With this patch we're not maximizing on low resolutions which I thought was one of the main objectives of this bug.

Fitt's law to what end? For moving the window? The top edge would be reserved for resizing the window vertically, not for moving it. Plus:

Hmm, have I messed up the logic? This seemed to work as expected when I tested it. E.g. I had to unmaximize in order to take the two screenshots I attached.

The bookmarks toolbar isn't shown by default, so I'm not sure why you're including it here. Either way, I still think we should optimize the size for moving the window, interacting with other windows and the desktop, etc. when the user explicitly unmaximizes the window. Also, we should make those Mozilla-controlled pages more responsive.

Attachment: screenshot

Fresh Firefox windows look quite bad and awkward on 1280x800 and OS X 10.11.

It seems that this change was made for wrong and really unacceptable reasons "We need to just make this happen asap as we have data that shows screen resolution is negatively impacting conversion rates of the Firefox Accounts sign up flow on /firstrun/", "the green button now does fullscreen but the "zoom" option, the OS X equivalent of maximize, is still in the "Window" menu of most applications, including Firefox."

I don't know if default window size should be changed, on what platforms Firefox should start maximized but this change should be reverted because optimal window size wasn't even properly considered. (and bloated Mozilla pages should be fixed on their side)

You were most likely hitting bug 1240085 where the screen calculations were wrong for HiDPI. Try again on today's Nightly. If the problem persists, please file a new bug blocking this one and include the output of window.screen.availWidth and window.screen.availHeight from a Fx console.

Name 	        Firefox
Version 	46.0b2
Build ID 	20160314144540

OS              Windows 7 SP1 x86_64

Actual Results: 
As expected

Expected Results: 
Firefox is able to start maximized on first run.
If I am restarting with restore down, it starts with same window size.

In short, On first run, maximize while on restart, window size before restart.
