I think we need to clear this up a little before this can get written. Do we want to measure the number of tabs a tab is opened, or just count the number of tabs in all windows at the point of the ping?
Blocks: 944453
We're interested in how many tabs people have, and whether that changes with Australis (because, for instance, background tabs are less intrusive), so the count of number of tabs (perhaps per-window?) at the point of the ping will give us a reasonable answer, I believe.
So would collecting an array of tab counts (1 count per window) be sufficient?

Yes, that sounds good to me. Thanks!

Do we want to count hidden panorama groups that even the user might have forgotten about? Maybe we want visibleTabs here? Should we collect both?

Blake, do you have a position on that? I tend to agree with Gijs that visible tabs is what we want here.
Flags: needinfo?(bwinton)
Yeah, visible tabs sounds like what we're interested in. (having said that, hidden tabs _would_ be another interesting thing to measure. :)
Flags: needinfo?(bwinton)
Alright, this records counts for both visible and hidden tabs.

Removing Australis:P1 whiteboard tag because these already block an Australis:P1 bug, and being redundant isn't helpful.

At least on OS X, with bug 952180 landed, the tabs will always return 1 active tab, and no hidden tabs, making this measurement useless. So, do we: 1) Not care enough about this probe to change it? 2) Update the probe to count the tabs at some time between browser startup and before browser shutdown? If so, what is that time?

Why? If you use tab groups, there should be hidden tabs, too... I just ran this: let winEnumerator = Services.wm.getEnumerator("navigator:browser"); let visibleTabs = []; let hiddenTabs = []; while (winEnumerator.hasMoreElements()) { let someWin = winEnumerator.getNext(); if (someWin.gBrowser) { let visibleTabsNum = someWin.gBrowser.visibleTabs.length; visibleTabs.push(visibleTabsNum); hiddenTabs.push(someWin.gBrowser.tabs.length - visibleTabsNum); } } console.log(visibleTabs.join(','), hiddenTabs.join(',')) Which produces: "47" "6"

If you use tab groups, there should be hidden tabs, too... Because bug 952180 made it so that we looked for these tabs immediately after first paint, which was too soon - the session hadn't been restored yet. This guaranteed an active tab count of 1 and a hidden tab count of 0. Bug 956138 landed, however, which fixes this by making it so that we gather measurements after the sessionstore-windows-restored event fires.
So this is fixed, and I don't need to provide info? ;)

This is a straight-port from the non-Australis patch.
